How do the Process Model, WBS, SPMP, Goal Statement,

1
Example

• How do the Process Model, WBS, SPMP, Goal
  Statement,
• etc. etc. etc.
• all fit together?

2
The Problem

• We manufacture widgets. Sometimes our stock of
  raw materials runs too low, and production must
  slow down / stop.
• Hence, we need software that will automatically
  forecast raw materials needs for purchasing based
  on analysis of various data sets (production
  equipment, sales orders, etc.)

3
Possible Solutions

• Plan A
• buy it off-the-shelf
• Plan B
• build it ourselves

4
Approach

• Build it a piece at a time
• start with easy decision
• feasibility of getting the needed data, determine
  algorithms, etc.
• second version will address overall look and feel
• third version will implement most important
  decision
• create something that concretely shows project's
  value
• repeat until done

5
Step One - getting organized

• create a goal statement
• identify the key players
• keepers of data
• champions of the project
• final decision makers
• etc

6
Step Two - Write the SOW

• Statement of Work Contents
• Goal
• Scope
• Deliverables
• Criteria for Success
• etc

7
Step Three - Process Model Selection

• Spiral Life Cycle
• Gather Requirements
• Design
• Code
• Test
• Repeat

8
Step Four - Plan Activities

• How do we decide what all we need to do?
• Based on Past WBSs
• Based on Brainstorming about Tasks
• Based on IEEE 1074

?
9
Step Four - Using 1074 to select activities

• 6. Plan Project Management
• 7. Analyze Risks
• 9. Manage the Project
• 10. Retain Records
• 11. Implement Problem Reporting
• 15. Identify Quality Improvement Needs
• 16. Identify ideas and needs
• 17. Formulate Potential Approaches

• 25. Define Interface Requirements
• 28. Define Database
• 29. Design Interfaces
• 30. Develop Algorithms
• 32. Create Test Data
• 33. Create Source Code
• 37. Perform Integration
• 50. Execute VV Tasks
• 54. Execute the Tests

10
Step Five - Build the Work Breakdown

• Major Activities in the WBS
• 1. Project Functions
• 2. Conduct Feasibility Study
• 3. Design Interface Architecture
• 4. Most Important Problem
• 5. Next Problem
• 6. Re-Evaluation of Project
• 7. Development Continuation
• 8. Deployment

11
Step Five - Build WBS

• 1. Project Functions
• 1.1 Retain Records (10)
• 1.2 Plan Configuration Management (55)
• 1.3 Perform Configuration Control (57)
• 1.4 Collect and Analyze Metric Data (51)
• 1.5 Produce Internal Documentation (61)

12
Step Five - Build WBS

• 2. Feasibility
• 2.1 Analysis
• 2.1.1 Identify Major Needs (16)
• 2.1.2 Formulate Potential Approaches(17)
• 2.1.3 Decide what is easiest to do.
• 2.2 Design
• 2.2.1 Design Database (28)
• 2.2.2 Design Interfaces (29)
• 2.2.3 Develop Algorithm (30)

• 2.3 Code
• 2.3.1 Create Test Data (32)
• 2.3.2 Create Source Code (33)
• 2.4 Test
• 2.4.1 Execute Tests (54)
• 2.4.2 Execute VV (50)
• 2.4.2.1 Is this Worthwhile?
• 2.4.2.2 Determine key problem for next phase
• 2.4.2.3 Decide if to go forward

• Step Six - Estimate Size and Duration
• Step Seven - Estimate Cost
• Step Eight - Use WBS and size estimates to create
  project plan
• Step Nine - Begin Activities 1 and 2
