• Checkpoints of the Process
• (from Chapter 9 of Royce book)

2
Topics for Today

• Major Milestones
• Minor Milestones
• Periodic Status Assessments

3
Review - Seven Software Process Workflows

• Management
• Controlling the process.
• Environment
• Automating the process.
• Requirements
• Analysis and evolving requirements artifacts.
• Design
• Modeling and evolving the architectures and
  design artifacts.

• Implementation
• Programming and evolving the implementation and
  deployment artifacts.
• Assessment
• Assessing trends in process and product quality.
• Deployment
• Transitioning the end products to the use.

4
Review - Artifacts Associated with Workflows
5
Review - Iteration Workflow

• Design
• Evolving the architecture and baseline design,
  design and test models, updating design set
  artifacts.
• Implementation
• Developing and acquiring new components,
  integration and testing.
• Assessment
• Evaluating the results of the iteration
  compliance, quality, performance. Change
  decisions.
• Deployment
• Transitioning the release to users, IVV
  contractor, customer, regulators.

• Management element
• Planning for the release, use case selection,
  detail assignments.
• Environment
• Evolving the change order database for new
  baselines for product, test and environment
  components.
• Requirements
• Analyzing the requirements artifact set,
  elaborate use cases and evaluation criteria.

6
Review - Typical Build Sequence
7
Management Reviews

• Major milestones
• System-wide reviews at end of each of the four
  phases.
• Minor milestones
• Iteration-focused events to review iterations.
• Includes a release specification (release plan
  and evaluation criteria), and release description
  (results of the evaluation of the release.)
• Status assessments
• Periodic events to assess progress.

Checkpoints
9
Major Milestones Reviewers

• Customers
• Schedules, budgets, feasibility, risk assessment,
  requirements, progress, compatibility.
• Users
• Requirements, usage scenarios, growth, quality.
• Architects
• Requirements changes, tradeoffs, completeness,
  balance.

• Developers
• Requirements details, consistency, resolution of
  risks, environment.
• Maintainers
• Sufficiency of product and documentation
  artifacts, understandibility, interoperability,
  environment.
• Others
• Regulators, IVV contractor, subcontractors,
  associate contractors, sales, marketing.

10
Status Across Major Milestones
11
Life-Cycle Objectives Milestone

• Occurs at end of Inception Phase.
• Includes Plan, estimated cost and schedule,
  expected benefits, vision statement andcritical
  issues, operational concept.
• Contains draft architecture document.
• Contains a prototype architecture demonstration.
• Goal Authorization to proceed to Elaboration
  Phase.

12
Life-Cycle Architecture Milestone

• Goal
• Demonstrate an executable architecture.
• Authorization to Proceed with the construction
  phase.
• Includes
• Detailed plan for the construction phase,
  critical issues regarding requirements and the
  operational concept, baseline architecture,
  baseline vision, baseline software development
  plan, evaluation criteria for the initial
  operational capability milestone.

13
Readiness for Architecture Milestone

• Critical use cases defined and scenarios prepared
  for evaluating architecture
• Stable architecture baselined and demonstrated.

• Risk profile is well understood. Common
  understanding of outstanding risks, and
  mitigation plans fully elaborated.
• Development plans for remaining phases are
  defined.

14
Architecture Milestone Contents

• Presentation and Overview of the current state of
  the software project.
• A configuration-controlled set of all engineering
  data for the engineering artifacts.
• An executable demonstration of capability.

15
Architecture Milestone Artifacts
16
Architecture Milestone Agenda
17
Initial Operational Capability Milestone

• Goals
• Assess readiness to begin transition into
  customer and user sites.
• Authorize beginning of acceptance tests.
• Items for Milestone
• Installation instructions and issues, software
  version descriptions, user and operator manuals,
  support for user sites, test environment, and
  test software.

18
Product Release Milestone

• Goal
• Assess the completion of software and its
  transition.
• Milestone contents
• Results of acceptance testing, open issues,
  installation issues, support issues.

19
Minor Milestones

• Primarily, iteration readiness reviews and
  iteration assessment reviews.
• Early iteration focus
• Design and analysis, discovery, experimentations,
  risk assessment.
• Later iteration focus
• Completeness, consistency, usage, and change
  management.
• Other minor milestones.
• Test readiness reviews, test results, special
  issues.

20
Typical Minor Milestones
21
Periodic Status Assessments

• Assessments are crucial for focusing management
  attention on the health of the project.
• Generally status assessments are held each month
  or each quarter during the project.
• Preparations ideally should include no more than
  one days effort by the software project manager.
  (Use day-to-day material to prepare the
  presentation.)
• Assessments also can be used for
  project-to-project comparisons, and dissemination
  of best practices within the organization.

22
Status Assessment Reviews
23
Summary for Checkpoints of the Process

• Checkpoints provide for control of the
  development process.
• Major Milestones are the Objectives,
  Architecture, Initial Operational Capability, and
  the Product Release Milestones.
• Minor Milestones are for iteration readiness and
  iteration results reviews.
• Periodic Assessment Reviews are for focusing
  management attention on the health of the project.

24
