Life cycle Flashcards
Features of Linear
Concept, Definition, Deployment, Transition
Benefits of iterative
- Flexible nature, accommodate vague scope. 2. Bc iterations, able to easily incorporate change to project scope. 3. Allows for development of multiple solutions. 4. Allows for early benefit realisation as can deploy products early. 5. Allows for stakeholder input to be incorporated into next iteration - meeting their requirements better.
Limitations of iterative
Don’t know how expensive, don’t know how long it will take More complex resource management.
Features of Iterative
Feasibility, foundation (project charter) Evolutionary Development
Benefits of linear
- Allows for maximum control and governance. 2. Strict deadlines. 3. Tight budget. 4. Easier resource management. 5. Easier process to follow - pass information along at end of each phase.
Limitations of limited
Less flexible - adding in change. Have to make decisions early. Takes longer to realise benefits.
Features of Hybrid
Adds iterations to linear lifecycle
Benefits of hybrid
Completely customisable. Increase efficiency effectiveness of project, more success, more benefits bc bespoke
Limitations of hybrid
Can be difficult to manage. If not managed correctly, can be ineffective.impact project success.
Extended lifecycle (differences from linear
Need to plan more scope (operating procedures). Benefit management more important, cost of termination taken into account. Cashflow returns from useable product will be included to offset cost of project and will have impact on justification for project
when to use each life cycle
Iterative - when scope is vague, when want lots of stakeholder input. Linear - when want lots of control, strict guidelines, strict budget, strict deadline
What can impact which life cycle we choice>
Organisational preferrence. Appetite for risk
