2 reasons for phases in linear lifecycle
- To support governance
(clear decision points, roles/responsibilities, processes, confidence at board level, go/no-go decision points ensure viable projects proceed, stops waste (money/resource), opportunities to revise budgets / timescales) - Makes them easier to manage
(Mini-projects, team know what to do at each stage, removes ambiguity, documents responsibilities, consistency across organisation, resource can be planned)
3 reasons a project may close early
- It becomes unviable
- Product failure due to technical reason
- Requirements significantly change
2 differences between lifecycle and extended lifecycle
- Project delivers the product / extended realises the benefits
- Roles and responsibilities involved
3 differences between linear and iterative lifecycle
- Number of passes through the lifecycle phases
- Level of uncertainty in output
- The length of time to realise benefits
4 ways knowledge / information management support decision making
- Support gate decisions
- Gather information from stakeholders and understand their changing needs
- Avoid mistakes / repetition through lessons learned.
- Take action in response to data.
