Description
[0001] This application claims the benefit of Provisional Application Nos. 60/187,481 filed on 7 Mar., 2000 and 60/198,915 filed on 20 Apr. 2000.
FIELD OF INVENTION
[0002] This invention relates to intelligent project planning and execution and to optimized project planning procedures.
BACKGROUND OF THE INVENTION
[0003] Project planning is a discipline focused on determining, structuring, and scheduling the minimum work necessary to produce the outcomes defined for the scope of the project in the least amount of time under known constraints (e.g., resource availability, regulatory requirements, etc.).
[0004] Planning complex projects often requires the synthesis, scheduling, and coordination of the activities of many individuals having expertise in distinct disciplines or professions.
[0005] In most cases, each discipline or profession will have developed, and formally documented, a body of knowledge that is considered to express its best practices. Generally, each body of knowledge will describe proven and optimal approaches used to achieve specific outcomes associated with the discipline or profession (e.g., the extraction of a wisdom tooth by a dental surgeon, or the design of a user interface for a computer software application by a software engineer).
[0006] The approaches described are typically represented in the body of knowledge as a series of interdependent activities.
[0007] Combining the activities from more than one body of knowledge into a coherent and optimal whole, as represented by a project work breakdown structure (WBS) and work flow, to satisfy the set of outcomes anticipated by the scope of the project can be daunting, given that the project planner must rationalize, synthesize, and set dependencies between hundreds or thousands of discrete activities from the bodies of knowledge involved, without having the benefit of expertise in all of the disciplines or professions.
SUMMARY OF THE INVENTION
[0008] The invention comprises a method, process and system for synthesizing an optimized process flow, an activity abstraction hierarchy and an instruction set that represents the minimal work to produce at least one outcome. An embodiment of this invention utilizes a single set of non-redundant activities and activity dependencies, which has already been derived from an organization's current processes and procedures, to produce an optimized work flow with respect to the desired outcomes for a project. To accomplish this, the conditional execution requirements of each activity required to produce a specified outcome are recursively examined to identify the set of activities which must be completed to arrive at the outcome. Starting with the last of these activities, a determination is made as to whether the activity is already present in the subject project work plan. If the activity is not present, but should be, it is inserted into its correct position in the project's work breakdown structure and is linked into the work flow for each predecessor and successor activity already present in the project's work breakdown structure. Working upstream along the process chain from that identified last activity, the process of activity insertion/positioning and work flow linking continues until all activities in the process chain of the outcome have been considered for insertion. Higher level summary activities are also introduced into the project's work breakdown structure as the lowest-level activities are inserted by referencing a designated work breakdown structure template.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0031] The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is merely made for the purpose of describing the general principles of the invention. The scope of the invention should be determined with reference to the claims.
[0032] This mode may be characterized as a rule-based approximation, synthesis, and reduction approach. The planner may start synthesis and reduction with either an empty plan or with a plan that approximates the anticipated final work breakdown structure and work flow required for the scope of the project being planned. The approximation can be chosen from a set of known and useful “stock” plans. A “stock” plan is a previously constructed work breakdown structure (WBS) and work flow (with component activities linked to appropriate instructional content), which have proven useful on past projects. Each stock plan describes the work necessary to achieve one or more outcome. In the synthesis and reduction approach one develops a custom work flow by synthesizing the work flows necessary to achieve desired outcomes not present in the plan and by de-synthesizing, or reducing, the plan's work flows by removing activities that are solely required for outcomes which are currently present in the plan, but which are not wanted.
[0033] A process and system is disclosed to assist work planners by assembling a work breakdown structure (WBS) and work flow for a project based on the explicit selection or deselection of outcome(s) by a work planner from a defined set of possible outcomes. The process and system ensure that the resulting project WBS and work flow is composed of the minimum set of activities required to produce the set of outcomes desired for the project.
[0034] The process and system further ensure that the project's activities are organized into an activity hierarchy defined by a WBS template designated by the work planner, and that each of the project's activities is linked into an appropriate work flow, supported by appropriate instructional content.
[0035] In cases where the projects undertaken require different sets of outcomes, and where the work needed for one outcome may satisfy some or all of the work needed for another outcome, the determination of a rigorously optimized WBS and work flow to produce a desired set of outcomes (where hundreds or thousands of work steps are involved)is not typically feasible.
[0036] The present embodiment leverages the manufacturing and information technology principles of interchangeable/reusable components by recognizing that a single, non-redundant set of activities and activity dependencies can be derived from multiple formally documented bodies of knowledge and that this set of activities and activity dependencies can be used to assemble optimized project work breakdown structures (WBSs) and work flows based on the work planner's selection and/or de-selection of outcomes to be achieved by the project being planned.
[0037] In this context, an “optimized” WBS and work flow for a project means a WBS and work flow that is composed of the minimum set of activities necessary to produce the set of outcomes desired by the project.
[0038] The outcome-driven work flow synthesis process provides a system and method for the work planner or other user to implement the following:
- [0039] 1) View the available WBS templates;
[0040] 2) View outcomes within and outside of the scope of each WBS template;
[0041] 3) Choose and transmit a “controlling” WBS template selection;
[0042] 4) Choose and transmit one or more selected outcome for synthesis;
[0043] 5) View the resulting WBS and work flow; and
[0044] 6) Link each activity in the activity hierarchy represented by a project's WBS with the appropriate instructional content.
[0045] The outcome-driven work flow reduction process provides a system and method for the work planner or other user to do the following:
- [0046] 1) View the outcomes currently resulting from an existing project's WBS and work flow;
- [0047] 2) Choose and transmit a selected outcome for removal from the WBS and work flow;
- [0048] 3) View the resulting project WBS and work flow.
[0049] Taken together, the outcome-driven synthesis and reduction processes provide work planners with the ability to construct and tailor work breakdown structures and work flows, supported by relevant activity descriptions (i.e., instructional content), by simply considering and selecting the outcomes that the project is intended to achieve.
[0050] The following terminology is grouped together here as a lexicon for use in describing embodiments of the invention.
[0051] Activity—a specific unit of work
[0052] Elementary Activity—the smallest unit of work that produces a meaningful result for the project.
[0053] Elementary Activity Dependency—An association between two elementary activities such that an execution of the first results in a state, or set of conditions, required by the second. The state resulting from the execution of an elementary activity is called a post-condition. The state required by a dependent elementary activity is called a “pre-condition”.
[0054] Instructional Content Page—a document (e.g., an HTML document)used to describe the purpose or intent of, and approach to, the conduct of an activity. Each instructional content page may contain formatted text, graphics, and hyperlinks to related instructional content
[0055] Non-Elementary Activity —a named grouping of lower-level activities (non-elementary or elementary) that serves as an abstraction of its subordinate activities.
[0056] Object Class—a type of person, place, thing, concept, event, association, or condition for which information (in the form of attribute values and relationships) may be saved and upon which operations (actions)may be performed.
[0057] Outcome—a defined result of a process (e.g., a manufactured part or final product, an architectural drawing, a conceptual model, a decision made, a judgement rendered, a presentation delivered, a state of being achieved).
[0058] Project—an organized undertaking to produce or accomplish one or more desired outcome from a set of possible outcomes.
[0059] Project Activity—represents the use of an elementary activity or non-elementary activity by a project.
[0060] Project Activity Dependency—represents the use of an elementary activity dependency in the workflow for a project.
[0061] Project Planning—a discipline focused on determining, structuring, and scheduling the minimum work necessary to produce the outcome(s) defined for the scope of the project in the least amount of time under known constraints (e.g., resource availability, regulatory requirements).
[0062] WBS Activity—defines the use and positioning (i.e., vertical positioning and indention level) of an activity in a WBS template.
[0063] WBS Template—a named hierarchical structure used as a pattern for organizing project activities into a work breakdown structure (WBS).
[0064] Work Breakdown Structure (WBS)— a hierarchy of project activities used to view and manage the work of a project at different levels of abstraction.
[0065] Work Flow—a network of interdependent elementary activities that terminates in the elementary activity associated with the production of an outcome.
[0066] This workflow development process is designed for use on large-scale projects, including analysis of business strategies, such as where to go with new product development, or reorganization of a large-scale enterprise (e.g. large corporation). Therefore, the results of the workflow development process must be without error and must be capable of handling inputs from disparate sources, e.g., in a corporation, from a research and development unit or division, a manufacturing unit or division, a human resources unit or units, an upper management oversight unit and a reorganization plan (simultaneously with a reorganization of the corporation for carrying out the major project). The workflow development must be done in a manner such that the risk to the enterprise utilizing the work flow development process must be minimized, as well as to the risk to a consulting company providing guidance with its work flow development process. For example, a work plan development process, if it were applied to the development of the B-2 Bomber, would have entailed the reorganization of a corporation to have a whole new large division, staffing such a division, having ongoing research and development input, designing the aircraft with thousands and thousands of specifications and requirements, a manufacturing unit, again with thousands of documented procedures, test units with thousands of tests and test documentation, acceptance tests procedures and manuals for the Air Force. These are extremely complex processes and the costs may be 100's of billions of dollars.
[0067] However, it would be desirable to have a system which, in addition to the rule based structure, has an additional element or aspect which allows the work breakdown structure of the flow of the work, in the execution of the project, to be optimized. Now, there are potentially a number of different ways of optimizing the work breakdown structure, that is, the flowcharts detailing how the work needs to be done. In this embodiment, one may start with a previously developed project plan that is considered to be similar to the plan required for the anticipated project. However, the planner may find that desired outcomes are not included in the “stock” plan, and so adds them. That is, one selects one or more outcomes for synthesis. Consequently, the work flow for the selected outcome is synthesized into the current work plan. Similarly, irrelevant outcomes may be present, so the planner subtracts them. Many interdependent elementary activities may be involved in achieving the various outcomes. Adding or removing an outcome requires the readjustment of the project's work flow and work breakdown structure. One may also start with an empty plan, i.e., a plan with no outcomes, and add outcomes to that empty plan.
[0068] FIG. 1 shows a computer-based system where RAM 12 and ROM 14 are shown. Other components of a computer-based system are shown including a central processing unit (CPU) 16, a video display unit 18, a communications port 20, an intermediate server 22, a remote web server 24 and a local web server 26. The data storage repository 28 includes Activities 30, Objects 32, Outcomes 34, Projects 36, Instructional Contents 38 and Work Breakdown Structure (WBS) Templates 40.
[0069] FIG. 2 shows the Entity Relationship Diagram (ERD) for the Exemplary Planning System Data Repository. Terms having all letters capitalized (e.g., ELEMENTARY ACTIVITY 58) refer to FIG. 2 . Definition of terms are listed in the lexicon, above.
[0070] The OBJECTS subject area 42 contains OBJECT CLASS 44, which is the subject of one or more OBJECT EFFECT 48 in the ACTIVITIES subject area 46. Each OBJECT EFFECT 48 always results from one ELEMENTARY ACTIVITY 58. Each ELEMENTARY ACTIVITY 58 always is a component of one NON-ELEMENTARY ACTIVITY 56 and may be identified as successor or predecessor on one or more ELEMENTARY ACTIVITY DEPENDENCY 50. In the OUTCOMES subject area 60, each OUTCOME 62 is produced by an ELEMENTARY ACTIVITY 58. In the PROJECT WBS/WORK FLOWS subject area 64, the PROJECT 70 is composed of one or more PROJECT ACTIVITY 68, which may be identified as a predecessor or successor on one or more PROJECT ACTIVITY DEPENDENCY 66. Each PROJECT ACTIVITY 68 may correspond to an ACTIVITY 52 which comprises ELEMENTARY ACTIVITY 58 and NON-ELEMENTARY ACTIVITY 56. The INSTRUCTIONAL CONTENT subject area 72 contains CONTENT PAGE 74 which may be referenced by one or more WBS ACTIVITY 80 which is in the WBS TEMPLATES subject area 76. Each WBS ACTIVITY 80 always references one ACTIVITY 52 and may override one or more ELEMENTARY ACTIVITY DEPENDENCY 50. Each WBS TEMPLATE 78 may provide a controlling WBS for one or more PROJECTS 70.
Outcome-Driven Work Flow Synthesis Process
[0071] This process is initiated when the work planner at step 96 (FIG. 3 a) confirms one or more OUTCOMES 62 to be produced/achieved by his or her PROJECT 70. This process will introduce all needed ACTIVITYs 58, 56 into the PROJECT 70, as PROJECT ACTIVITYs 68, to form an appropriate WBS and workflow. Each PROJECT ACTIVITY 68 will also be linked to the INSTRUCTIONAL CONTENT PAGE 74 that is appropriate for the controlling WBS TEMPLATE 78 selected by the Work Planner. The choice of the WBS TEMPLATE 78 sets the context for the PROJECT 70.
[0072] For each OUTCOME 62 selected by the Work Planner from the set of possible OUTCOMES 60, perform the following procedures:
[0073] Procedure 1: From the Planning Data Repository, at step 98 (FIG. 3 a) the ELEMENTARY ACTIVITY 58 is selected that produces the OUTCOME 62 (selected in step 96) the Work Planner wishes to add to his or her PROJECT 70.
[0074] The selected ELEMENTARY ACTIVITY 58 will be the last point, or node, in the work flow that results in the OUTCOME 62. The last node 94 in a work flow is commonly referred to as the “terminal”, or “most-downstream” node. As an example,
-
- [0075] where denotes ELEMENTARY ACTIVITY; and
of the five ELEMENTARY ACTIVITIES shown, the one furthest downstream, i.e., in the direction indicated by the downstream arrow, is the terminal node 94.
- [0075] where denotes ELEMENTARY ACTIVITY; and
[0076]
[0077] Procedure 2: At step 100 (FIG. 3 a) determine whether the ELEMENTARY ACTIVITY 58 selected in step 98 has already been included in the PROJECT 70 as a PROJECT ACTIVITY 68. If it has been included, then at step 150 select the next desired OUTCOME 62. If it is found, return to step 98. If it is not found, end the process, at step 152. If it has not already been included, insert an entry into the Node Processing Table 114 at step 102 representing the ELEMENTARY ACTIVITY 58, as illustrated in the sample table below, and then continue.
[0078]
| Grouping | Processed | |||
|---|---|---|---|---|
| Entry Seq. # | Node ID | Indicator | Indicator | Removal Indicator |
| 1 | 12387 | N | N | N |
[0079] The columns in the Node Processing Table (NPT) 114 (FIGS. 3 a, 3b) are defined as follows: “Entry Seq #” records the insertion order, or sequence, of entries (i.e., rows) in the Node Processing Table. “Node ID” records the unique identifier for an ELEMENTARY ACTIVITY 58 that participates as a node in the OUTCOME's 62 workflow. “Grouping Indicator” indicates whether the ELEMENTARY ACTIVITY 58 is classified as a “grouping” activity. A grouping activity is one that collects, or groups, other OUTCOMEs 62. Grouping activities are treated in a specialized way in the Outcome-Driven Work Flow Synthesis Process. “Processed Indicator” indicates whether all processing related to the node has been completed. This column is set to “N” when entries are inserted into the table, and is changed to “Y” when all processing related to the node has been completed. The column “Removal Indicator” is not used for Outcome-Driven Work Flow Synthesis. Instead, this column is used in the Outcome-Driven Work Flow Reduction process. The default value for this column is “N”.
[0080] Procedure 3:. At step 104 the first entry in the Node Processing Table 114 is selected. As discussed above, this entry will identify the most downstream node 94.
[0081] Procedure 4: Perform the following procedures 4.1 through 4.4 (FIG. 3 b) until all nodes have been processed:
[0082] Procedure 4.1: At step 106 (FIG. 3 b) a PROJECT ACTIVITY 68 record is inserted, corresponding to the ELEMENTARY ACTIVITY 58 referenced by the current node being processed, into the PROJECT 70 by performing the Activity Insertion, Positioning, and Content Linking process (described below).
[0083] Procedure 4.2: If the ELEMENTARY ACTIVITY 58 referenced by the current node being processed at step 108 (FIG. 3 b) is not classified as a “grouping” ELEMENTARY ACTIVITY 58 (i.e., the Grouping Indicator in the Node Processing Table=“N”), then at step 110 (FIG. 3 b) select its relevant upstream nodes. At step 112 (FIG. 3 b) insert an entry into the Node Processing Table for each relevant upstream node that is not already determined to be in the Node Processing Table 114 at step 154. For purposes of this step a “relevant upstream node” is defined as an ELEMENTARY ACTIVITY 58 that is identified as a predecessor of the ELEMENTARY ACTIVITY 58 referenced by the current node by an instance of ELEMENTARY ACTIVITY DEPENDENCY 50 where the following criteria are satisfied:
-
- [0084] (1) If the ELEMENTARY ACTIVITY 58 corresponding to the most downstream node is within the scope of the controlling WBS (i.e., it is referenced by a WBS ACTIVITY 80 that is a component of the controlling WBS TEMPLATE 78) then the candidate predecessor must also be referenced by a WBS ACTIVITY 80 that is a component of the controlling WBS TEMPLATE 78.
[0085] This criterion ensures that PROJECT ACTIVITYs 68 included in a PROJECT 70 are limited to those that correspond to an ELEMENTARY ACTIVITY 58 that is explicitly included in the controlling WBS TEMPLATE 78 (i.e., is within the scope boundary established by the controlling WBS TEMPLATE 78).
-
- [0086] (2) The ELEMENTARY ACTIVITY DEPENDENCY 50 identifying the candidate predecessor must not be overridden by a WBS ACTIVITY 80 for the controlling WBS TEMPLATE 78 associated with the current node, if one exists; and
- [0087] (3) A PROJECT ACTIVITY 68 corresponding to the candidate predecessor must not already exist for the PROJECT 70.
[0088] Procedure 4.3: At step 116 (FIG. 3 b) set the Processed Indicator for the current node to “Y” in the Node Processing Table. This also pertains to grouping ELEMENTARY ACTIVITIES from step 108.
[0089] Procedure 4.4: At 118 select the next unprocessed node in the Node Processing Table (i.e., lowest entry sequence number where the Processed Indicator =“N”)-this is referred to as the “current node” in the subsequent steps. If an unprocessed node is found, repeat the processing starting back at step 106. If no unprocessed node is found, then select the next desired outcome (step 150, FIG. 3 a) and continue according to step 150. Eventually all nodes and all outcomes will be processed and the processing will end.
Activity Insertion, Positioning, and Content Linking
[0090] When inserting a PROJECT ACTIVITY 68 into the PROJECT 70 that is within the scope of the controlling WBS TEMPLATE 78, check if a PROJECT ACTIVITY 68 corresponding to its parent WBS ACTIVITY 80 (as defined by the controlling WBS TEMPLATE 78) is already included in the PROJECT 70. If so, position the PROJECT ACTIVITY 68 being inserted one level below its parent in its correct position relative to any of its siblings which are already included in the PROJECT 70. If the parent is not currently included in the PROJECT 70, determine all missing higher-level NON-ELEMENTARY ACTIVITYs 56 based on the PROJECT's 70 controlling WBS TEMPLATE 78. All missing higher-level NON-ELEMENTARY ACTIVITYs 56 must be included in the PROJECT 70 by inserting corresponding PROJECT ACTIVITY's 68 into the PROJECT 70, in their correct relative positions to their siblings. Once all the missing ancestry (i.e., higher-level activities) has been included in the PROJECT 70, insert the PROJECT ACTIVITY 68 that corresponds to the ELEMENTARY ACTIVITY 58 one level below its parent in its correct relative position to any of its siblings which are already included in the PROJECT 70. Link each PROJECT ACTIVITY 68 inserted into the PROJECT 70 to the CONTENT PAGE 74 referenced by the WBS ACTIVITY 80 in the PROJECT's 70 controlling WBS TEMPLATE 78 that references the ACTIVITY 52 corresponding to the inserted PROJECT ACTIVITY 68.
[0091] When inserting a PROJECT ACTIVITY 68 into the PROJECT 70 that is not within the scope of the controlling WBS TEMPLATE 78, check if a PROJECT ACTIVITY 68 corresponding to its parent NON-ELEMENTARY ACTIVITY 56 is already included in the PROJECT 70. If so, position the PROJECT ACTIVITY 68 being inserted one level below the PROJECT ACTIVITY 68 corresponding to its parent NON-ELEMENTARY ACTIVITY 56, as the last PROJECT ACTIVITY 68 in that parent (positioning relative to siblings will not be known).
[0092] If not, insert both the PROJECT ACTIVITY 68 corresponding to the ELEMENTARY ACTIVITY 58 and a PROJECT ACTIVITY 68 corresponding to its NON-ELEMENTARY ACTIVITY 56 parent to the end of the PROJECT's 70 WBS 78 under a top-level PROJECT ACTIVITY 68 named “Activities to be Manually Positioned”.
[0093] Create a PROJECT ACTIVITY DEPENDENCY 66 to document each dependency between a PROJECT ACTIVITY 68 inserted into the PROJECT 70 and any of its predecessor and successor PROJECT ACTIVITYs 68 that have already been included in the PROJECT 70, based on any ELEMENTARY ACTIVITY DEPENDENCYs 50 related to the ELEMENTARY ACTIVITY 58 that corresponds to the PROJECT ACTIVITY 68. However, do not create a PROJECT ACTIVITY DEPENDENCY 66 to document a dependency in any case where the ELEMENTARY ACTIVITY DEPENDENCY 50 for the pairing has been overridden by a WBS ACTIVITY 80 that is a component of the PROJECT s 70 controlling WBS TEMPLATE 78.
Outcome-Driven Work Flow Reduction Process
[0094] This process is initiated when the work planner chooses to remove an OUTCOME 62 that is currently planned for his or her PROJECT 70. Once initiated, this process will remove any PROJECT ACTIVITYs 68 in the subject OUTCOME's 62 work flow that does not participate in any This process is initiated when the work planner chooses to remove an OUTCOME other planned OUTCOME's 62 work flow currently in the PROJECT 70.
[0095] Procedure 1. From the Planning Data Repository 28, at step 160 (FIG. 4 a) select the PROJECT ACTIVITY 68 corresponding to the ELEMENTARY ACTIVITY 58 that produces the OUTCOME 62 the work planner wishes to remove from the PROJECT 70.
[0096] The selected PROJECT ACTIVITY 68 will be the last point, or node, in the work flow that results in the OUTCOME 62 to be removed. As above, the last node 94 in a work flow is commonly referred to as the “terminal”, or “most-downstream” node.
[0097] Procedure 2. At step 162 insert an entry into the Node Processing Table 114 (FIG. 4 a) representing the PROJECT ACTIVITY 68, as illustrated in the sample table below, and then continue with step 164.
[0098]
| Grouping | Processed | |||
|---|---|---|---|---|
| Entry Seq. # | Node ID | Indicator | Indicator | Removal Indicator |
| 1 | 12387 | N | N | N |
[0099] The columns in the Node Processing Table (NPT) 114 (FIGS. 3 a, 3b, 4a, 4b, 4c) have already been defined, above.
[0100] Procedure 3. At step 164 (FIG. 4 a) select the first entry in the Node Processing Table 114. As discussed above, this entry will identify the most downstream node 94 (above).
[0101] Procedure 4. Perform procedures 4.1 through 4.4 (FIGS. 4 b, 4c) until all nodes have been processed.
[0102] Procedure 4.1: Set the removal Indicator in the Node Processing Table for the current node to “Y” in step 190 if one of the following is true:
-
- [0103] (1) The ELEMENTARY ACTIVITY 58, corresponding to the PROJECT ACTIVITY 68, at step 166, identified by the current node, produces an OUTCOME 62, at step 166, which was identified at step 192, as being selected for removal; or
- [0104] (2) The ELEMENTARY ACTIVITY 58 corresponding to the PROJECT ACTIVITY 68 identified by the current node, does not produce an OUTCOME 62 and the PROJECT ACTIVITY 58 does not have any immediate successor PROJECT ACTIVITY's 68 in the PROJECT 70 that have not been marked for removal in the Node Processing Table 114, as determined at step 194. This test insures that a PROJECT ACTIVITY 68 that is part of the work flow of another OUTCOME 62 currently included in the PROJECT 70 does not get removed, as determined at step 194. If all the successors have not been marked for removal in the Node Processing Table 114, the procedure continues to step 170 (
FIG. 4 c).
[0105] Procedure 4.2: If the ELEMENTARY ACTIVITY 58 identified by the current node being processed at step 170 (FIG. 4 c) is not classified as a “grouping” activity and it has been marked at step 172 (FIG. 4 c) for removal,. At step 174 (FIG. 4 c) select all of its predecessors according to the PROJECT ACTIVITY DEPENDENCYs 66 and at step 176 (FIG. 4 b) insert an entry into the Node Processing Table 114 for each selected predecessor that is determined, at step 178, to not already have an entry in the Node Processing Table 114
[0106] Procedure 4.3: At step 180 (FIG. 4 c) set the Processed Indicator for the current node to “Y” in the Node Processing Table 114.
[0107] Procedure 4.4: At step 182 select the next unprocessed node in the Node Processing Table (i.e., the lowest entry sequence number where the Processed Indicator“N”). This is now the current node. If an unprocessed node is found at step 184, then return to step 166 (FIG. 4 c) and continue from that step 166.
[0108] Procedure 5: At step 186 remove each PROJECT ACTIVITY 68 corresponding to an ELEMENTARY ACTIVITY 58 that is designated for removal in the Node Processing Table from the PROJECT 70 according to the Activity Removal process. As this removal process proceeds, when removing a PROJECT ACTIVITY 68 from a PROJECT 70, check if it is the last PROJECT ACTIVITY 68 for its parent in the PROJECT's 70 WBS. If so, remove the PROJECT ACTIVITY 68 and its parent from the PROJECT 70. When removing the parent, check if it was the last child for its parent in the PROJECTs 70 WBS. If so, remove it and its parent. Continue this child/parent removal process until a parent PROJECT ACTIVITY 68 that has other children is found or the last ancestor of the current PROJECT ACTIVITY 68 has been removed from the PROJECT 70. The processing ends at step 188.
EXAMPLE 1
Outcome-Driven Work Flow Synthesis Process
[0109] For this example, the user has selected one outcome, outcome “O3”, for synthesis and has selected the exemplary WBS controlling template shown in FIG. 5 a as the controlling WBS for the project. The procedures identified below correspond to the numbered procedures in the description of the Outcome-Driven Work Flow Synthesis Process, above.
[0110] Procedure 1: Elementary activity EA B1.3 produces the outcome that the user wants to add to the project (i.e., outcome O3), so elementary activity EA B1.3 is selected from the Planning System Data Repository. See FIG. 5 a.
[0111] Procedure 2: Since a project activity corresponding to elementary activity EA B I0.3 has not already been included in the project, an entry is inserted into the Node Processing Table:

EXAMPLE 2 of the Outcome-Driven Work Flow Synthesis Process
[0188] In this example, after having selected outcome O3 and seeing the results in the Project WBS/Work Flow from EXAMPLE 1, above, the user decides to add Outcome O4. This illustrates how to synthesize an additional outcome into an existing Project WBS/Work Flow. It also shows the special processing associated with an Elementary Activity classified as a “grouping” activity. The notation follows that of EXAMPLE 1, above. FIG. 6 a provides an exemplary Project WBS and work scope of the controlling WBS used for this example.
Procedure 1
[0189] Elementary activity EA C 1.3 produces the outcome that the user (work planner) wants to add to the project (i.e., Outcome O4), so it is selected from the Planning System Data Repository 28 (FIG. 1 ).
Procedure 2
[0190] Since a project activity corresponding to elementary activity EA C 1.3 has not already been included in the project, an entry is inserted into the Node Processing Table as follows:

EXAMPLE 3
Outcome-Driven Work Flow Reduction Process
Procedure 1
[0233] Project activity EA A2.5 produces the outcome that the user (work planner) wishes to remove from the project (i.e., O2), so it is selected from the Planning System Data Repository.
Procedure 2
[0234] An entry is inserted into the Node Processing Table as follows:
[0235] Sample Node Processing Table-114
[0236]
| Grouping | Processed | Removal | ||
|---|---|---|---|---|
| Entry Seq. # | Node ID | Indicator | Indicator | Indicator |
| 1 | EA A2.5 | N | N | N |
Procedure 3
[0237] The first entry is selected in the Node Processing Table (shaded).

| Grouping | Processed | Removal | ||
|---|---|---|---|---|
| Entry Seq. # | Node ID | Indicator | Indicator | Indicator |
| 1 | EA A2.5 | N | N | Y |
[0243] Project activity EA A2.5 was identified as the activity that produces selected outcome O2. At the conclusion of the first execution of procedure 4.1 the state of the Node Processing Table is as shown.
[0244] Procedure 4.1 set the Removal Indicator for the current node to “Y” because the project activity identified by the current node produces the outcome selected for removal.
Following First Execution of Procedure 4.2:
[0245] Sample Node Processing Table-114
[0246]
| Grouping | Processed | Removal | ||
|---|---|---|---|---|

| 2 | EA A2.4 | N | N | N |
[0253] Procedure 4.4 selected the next unprocessed node in the Node Processing Table (selected node is indicated as the shaded row in the Node Processing Table). This action caused the node EA A2.4 to become the “current” node.
Following Second Execution of Procedure 4.1:
[0254] Sample Node Processing Table-114
[0255]
| Grouping | Processed | Removal | ||
|---|---|---|---|---|
| Entry Seq. # | Node ID | Indicator | Indicator | Indicator |
| 1 | EA A2.5 | N | Y | Y |
| 2 | EA A2.4 | N | N | Y |
[0256] Procedure 4.1 set the Removal Indicator for the current node to “Y” because the project activity identified by the current node does not produce an outcome and does not have any immediate successors in the Project WBS/Work Flow that have not been marked for removal in the Node Processing Table (EA A2.5 is its only successor and EA A2.5 has been marked for removal in the Node Processing Table).
Following Second Execution of Procedure 4.2:
[0257] Sample Node Processing Table-114
[0258]
| Grouping | Processed | Removal | ||
