Study Notes
Tasks, Durations, and Dependencies
- Tasks have effort (person-days) and duration (days)
- Dependencies are represented with (M#) where M1-M8 are specific dependencies
- T1 has a duration of 10 days with 15 person-days required
- T2 has a duration of 15 days with 8 person-days required
- T3 depends on T1 and has a duration of 15 days with 20 person-days required
- T5 depends on T2 and T4 and has a duration of 10 days with 5 person-days required
- T6 depends on T1 and T2 and has a duration of 5 days with 10 person-days required
- T7 depends on T1 and has a duration of 20 days with 25 person-days required
- T8 depends on T4 and has a duration of 25 days with 75 person-days required
- T9 depends on T3 and T6 and has a duration of 15 days with 10 person-days required
- T10 depends on T7 and T8 and has a duration of 15 days with 20 person-days required
- T11 depends on T9 and has a duration of 10 days with 10 person-days required
- T12 depends on T10 and T11 and has a duration of 10 days with 20 person-days required
Activity Bar Chart
- The activity bar chart shows the start and finish times for each task
- Tasks T1 and T2 start immediately
- Tasks T3 and T7 depend on T1 starting at week 1
- Task T8 depends on T4 starting at week 3
- Tasks T5 and T6 have multiple dependencies
- The project finishes in week 11
Staff Allocation Chart
- Jane is assigned to tasks T1, T3, T9, T10, and T12
- Ali is assigned to tasks T1 and T8
- Geetha is assigned to tasks T2, T6, T7, and T3
- Maya is assigned to task T8
- Fred is assigned to tasks T4, T8, T11, and T12
- Mary is assigned task T 5
- Hong is assigned to tasks T7 and T6
Estimation Techniques
- Organizations need to make estimates for software effort and costs
- Experience-based techniques rely on the manager's expertise from previous projects
- Algorithmic cost modeling utilizes formulas to calculate project effort based on product attributes and process characteristics
Estimate Uncertainty
- Estimates can vary significantly throughout the project's life cycle
- There is typically high uncertainty in the feasibility and requirement phases
- The code and delivery phases have lower uncertainty
Risk Management
- Risk management is concerned with recognizing risks and planning to minimize their impact
- Software risk management is important because of inherent uncertainty in software development
- Risks can arise from loosely defined requirements, changing customer needs, difficulties in estimating resources and time, and differing skill levels
- Risks must be anticipated, their impact understood, and steps taken to avoid them
Risk Classification
- Risks are classified based on their type (technical, organizational, etc.) and what they affect
- Project risks affect the schedule or resources
- Product risks affect the quality or performance of the software
- Business risks affect the organization developing or procuring the software
Risk Examples
- Staff turnover is a risk affecting the project
- Management change is a risk affecting the project
- Hardware unavailability is a risk affecting the project
- Requirements change is a risk affecting the project and the product
Development Planning
- The project plan should be regularly adjusted as the project progresses
- The schedule, cost estimate, and identified risks must be revised regularly
- The process involves identifying constraints, risks, and milestones
The Project Planning Process
- The process includes identifying constraints and risks, defining the project schedule, defining milestones and deliverables, monitoring progress, and taking action to mitigate risk
Project Scheduling
- Project scheduling is about organizing the work into tasks and planning their execution
- Tasks are assigned effort and time estimates
- Resources required for each task are determined
Project Scheduling Activities
- Splitting the project into tasks and estimating time and resources
- Organizing tasks concurrently to optimize workforce utilization
- Minimizing task dependencies to prevent delays caused by waiting for other tasks to complete
- This process relies on the project manager's intuition and experience
