Understand project life cycles Flashcards
What are 2 key attributes of a linear life cycle
- sequential series of phases
- each phase give partial capability until final stage
what type of environments are linear lifecycle suitable for
stable, low risk nvironments
what are the phases of a linear lifecycle
- concept - initial idea
- definition - detailed definition, plans
- deployment - implementation of plans to realise outputs, outcomes and benefits
- transition - handover, commissioning and acceptance of outputs
what are 4 key attributes of a linear lifecycle
- stable
- predictable
- structured
- transparent management
what are pros of a linear lifecycle
- works well for deployment of clearly defined outputs
- balances time, cost and risk to achieve right scope and quality
what are the cons of a linear lifecycle
- assumes clear knowledge upfront
- resistant to change and inflexible
- long sequence of phases
- phases can create silos
- problems may be blamed on previous phase
what are the main attributes of an iterative lifecycle
- solutions are developed iteratively and incrementally
- agile approach
- several iterations allowing deployment of initial capability
- successive deliveries of further value
- different steps performed in parallel
what are the 6 phases of an iterative lifecycle
- pre-project - high level vision
- feasibility & foundation - finer detail
- evolutionary - specification and design -assemble, review, deploy - iterations
- deployment - incremental or full operational use
- post-project - delivered benefits
what are the attributes of a hybrid lifecycle
- pragmatic mix of approaches
- fusing predictive and adaptive approaches
what is an example of a hybrid lifecycle
- agile method for early requirements gathering with max uncertainty
- followed incremental or sequential processes
why are projects done as phases in linear lifecycle
- improved planning - stages, work packages and activities
- identification of priorities - focus on important factors
- effective risk assessment - go/no go decisions
- estimating accuracy - clearer basis as granular
- performance management - stage review
- continual improvement - lessons learned
- improved control - review objective and tolerances
- effective stakeholder comms
what differentiates a project from an extended lifecycle
- project lifecycles are concerned with delivering their outputs only
- extended lifecycles include management f change and benefits realisation
what are the 2 additional activities in an extended lifecycle
- adoption - operations and sustainment of the new project
- benefits realisation
what are implications of extending the lifecycle
- supplemental activities included in planning
- incorporated into concept and definition phases
- income and operational costs
- capital expenditure considerations
