what are the four phases of PM
- starting the project

What is a system development life cycle?
a framework for describing teh phases of developing information systems using five product or development life cycles.
which two factors have an influence on the decision on which cycle to use?
the degree of change in requirement and the frequency of delivery of useful results
What are the five different SDLC
- predictive life cycle
- iterative life cycle
- incremental life cycle
- adaptive life cycle
- hybrid life cycle
explain predictive life cycle
the scope, schedule and cost are determined early and changes to teh scope are carefully managed.
explain iterative life cycle
the scope is determined early but time and cost estimates are modified as the understanding of the product increases. this approach works best when there is a high degree of change and a low frequency of delivery
explain incremental life cycle
Deliverables are produced through a series of iterations that add functionality within a set time frame. The deliverable is not complete until after the final iteration. This approach works best when there is a low degree of change and a high frequency of delivery.
explain adaptive life cycle
Stakeholders define and approve the detailed scope before the start of an iteration, producing a useable product at the end of each iteration. PMI also refers to adaptive life cycles as agile or change-driven. This approach works best when there is a high degree of change and a high frequency of delivery.
explain hybrid life cycle
A combination of approaches is used based on the nature of the work. For example, some deliverables might have a low degree of change and low frequency of delivery such as weekly progress reports, a high degree of change and a high frequency of delivery such as certain software features, and so on.
What are the steps of scrum?
- product owner creates prioritized backlog
- project team creates a sprint backlog by taking task on top of the list in the backlog
- teams have daily scrum meetings during 2 - 4 week per sprint
- sprint results in a useful product
- sprint review
- repeat process
What is Kanban?
kanban uses visual cues to guide workflow. kanban helps improve day-to-day workflow, while scrum provides the structure for improving the organization of projects.
