Study Notes
Classic Waterfall Process
- In traditional waterfall process, software is decomposed into functions, and requirements are allocated to these components.
- This decomposition is different from object-oriented design and existing components.
Adversarial Stakeholder Relationships
- Conventional process often leads to adversarial stakeholder relationships due to difficulties in requirements specification and exchange of information through paper documents.
- Typical sequence of events in contractual software efforts:
- Contractor prepares a draft document, delivers it to customer for approval.
- Customer provides comments, contractor incorporates them, and submits a final version for approval.
Conventional Software Management
- Conventional software management practices are sound in theory but tied to outdated technology and techniques.
- Conventional software economics provides a benchmark of performance for conventional software management principles.
Software Economics
- Three important analyses of software engineering industry:
- Software development is still highly unpredictable.
- Management discipline is a key discriminator in success or failure.
- Software scrap and rework indicate an immature process.
Challenges of Software Development
- Only about 10% of software projects are delivered successfully within initial budget and schedule estimates.
- The best thing about software is its flexibility, but it also makes it difficult to plan, monitor, and control software development.
Importance of Documentation
- Documentation is necessary for:
- Communicating with interfacing designers, managers, and customers.
- Supporting later modifications by separate test teams, maintenance teams, and operations personnel.
- Documenting the design, as it is the real monetary value.
Do It Twice
- Arrange to develop a second version of the software, before delivering the final version to the customer.
- This is a smaller-scale process, done in a relatively short time frame.
