         Software Project Management Plan (SPMP)
Software Project Planning is a Key Practice Area for SEI Level 2.
Goals include:
1.Software estimates are documented for use in planning and tracking the
software project.
2.Software project activities and commitments are planned and documented.
3.Affected groups and individuals agree to their commitments related to the
software project.

PMP is also an important part of the Project Mgmt Body of Knowledge (PMBoK).

SPMP Describes:
1) What you are going to do
2) How to do it
3) When to do it
4) Who will do it
5) How much will it cost. (not always performed)

SPMP is a statement of understanding with development organization and team
members.
 Project manager writes the SPMP with team member input.
 SPMP may change as estimates are revised or requirements changes are
  necessary.
 When the SPMP changes, new agreement must be achieved and version
  control shall be used.

The project plan defines the work and how it will be done. It:
 Describes the milestones, their dates and deliverables.
 Provides a definition of each major task, an estimate of the time and
   resources required, and a framework for management review and control.
 Describes the responsibilities of the members of the project
 Describes the process and procedures to be used by the project
 Describes the software and hardware requirements to accomplish the project
 Defines the risks and assumptions of the project and how problem escalation
   should occur
 Defines the project tracking and communications techniques that should
   occur within the project, to upper management, to the customer
 For higher SEI levels: Defines the quality goals, quality expectations, and
   metrics to be collected.
 Is a powerful learning vehicle: a benchmark to compare with actual
   performance.

Executive Summary of Project.
 Project Overview: At a high level, what will the new software accomplish for
   the company?

   software packages are required and when are they required?
 Training Plan: What training is required for software developers/mgmt?
 Quality Plan: For SEI Level 4 and above: What quality goals does the project
   want to achieve? How many defects are we expecting to find? How do we
   expect to achieve quality?
 Reviews: Which software work products do we plan to review, and will they
   be group or one-person reviews?
 Risk Management Plan: List the expected risks and their probabilities,
   impacts, risk exposure, and a mitigation plan.

Project Tracking
 Measurement Plan: What units will we use to measure project size, effort,
   defects, elapsed time?
 Task Tracking: How will the project be tracked? How often will tracking
   methods (such as meetings) take place?
 Issues Tracking: How will customer, business manager issues be tracked
   and how often?

Lab: What is important for you to include in your SPMP? Who will do most of
the work? Start reaching agreement on important parts of SPMP.

                                        Risk
Risk: “A risk is something which may occur in the course of a project, and which, under
the worst outcome, would affect it negatively and significantly.”
-Eric Braude, Software Engineering

Risks can be categorized as:
Project risks: Impact the project schedule or resources
    E.g. H/W not delivered in time may delay project
Product risks: Affect the quality or performance of the developed software
    E.g. Poor training on new tool.
Business risk: Affects the business organization
    E.g. Obsolescence when product delivered.

What kinds of risks are the following?
   Programmer quits
   Requirements change
   Specification delays: Details not available
   CASE tool not performing as expected
   Basic technology is changed: OS upgrade

Stages of Risk Management include:
    Qualitative Risk identification: Identify from checklists, meeting reviews,
      brainstorming
    Quantitative Risk analysis: Assess likelihood and consequences of risks
    Risk planning: Address how the risk can be avoided or mitigated
    Risk monitoring: Periodically review status of risk

Qualitative Risk identification:
One method:
    Each team member spends 10 minutes considering his/hers greatest fears
       for the project (may review SPMP)
    The member then prepares a risk analysis for each risk and sends them to
       team leader.
    Team leader prioritizes and integrates the results producing a single risk
       analysis table.
    The group reviews the table for 10 minutes, to discover additional risks.
    The group finalizes the risk table for 10 minutes.
    Responsible engineers do risk retirement work outside the meeting
    Team members review risk at weekly meetings for 10 minutes.
Risks may be related to technology, people, the organization, tools, requirements
or estimation.
Risk may affect product performance, project cost/schedule, software
quality/support.

Quantitative Risk Analysis:
Assign numerical rating via estimation:
 Likelihood: The probability the risk will occur: not likely (0-30%), likely (30-
   70%), very likely (70-100%).
 Impact: The effects of the risk: rate 1 (low) to 10 (high) or: catastrophic (10),
   serious (7), tolerable (4), or insignificant (1)
 Priority: Once the Likelihood & Impact are known, the priority of risks can be
   determined. Priority = Likelihood x Impact
 Risks can be color coded according to Priority (red>7, yellow > 4, green<4)

Risk Planning:
 Avoidance Strategies: Take action to reduce probability of problem occurring
 Minimization Strategies: Take action to eliminate or reduce or mitigate
   negative effects for problem, if it occurs
 Transfer Strategies: Transfer risk to third party (e.g., insurance)
 Contingency Plan: Prepare a strategy to cope with problem, if it occurs.

Shall Risk Plan be implemented? Compare:
 $ to retire risk Vs.
 Expected Value (Cost(Risk) * Probability(Risk) )
Implement risk plan for top risks, when risk expected value > risk cost.

Decision Tree:

Risk Monitoring:
 Periodically assess the current status of risks: have the probabilities of risk
   increased or changed? Update or act on risk plan.
 Allocate responsibility for risk retirement activities.

Opportunities: Risks that offer potential $ benefits can also be ranked/acted
upon.
 High risk/high priority: Act on first
 Low risk/low priority: May ignore.
