Exam tips Flashcards
When can the project management plan be updated?
- once this plan is approved by sponsor, it cannot be changed.
Can be changed only if: - a change request is generated and approved by change control board.
- a change request has to go through the change control process (process name: perform integrated change control).
What if the project is terminated before completion?
- Proj.M should go to the closing process and formally close the project!!
- document what work was left to be done
- archive project records
- release people etc etc etc..
key is FORMALLY CLOSE PROJECT!!
What is a key input to the closing process?
- Accepted deliverables are a key input
What is important in process perform integrated change control?
- No change should be given to change control board without first assessing it.
- PM should find alternatives, assess the impact of each change before sending it for approval
Benchmarking
- comparison with other projects or industry standards
- one important tool used in process collect requirements
Gold Plating and Scope Creep
Gold plating - doing extra work not defined in the scope..
Suppose finishes the job earlier than expected, so you end up doing additional work which is not defined in scope. Extra work generally comes at the end of the project with
Scope creep - Unauthorized work getting added to scope
Stakeholders keep adding work without updating the scope statement. Pushes up budget, schedule, work, everything keeps growing.
Rolling Wave Planning
- tool for the process “Define Activities” (in Project Schedule Management)
- A form of progressive elaboration. Which means near term work packages can be defined in a much greater detail. Long term work packages cannot be defined in detail. Keep placeholders for long term work packages
- As project moves forward, placeholders will be removed, and work packages will be properly decomposed as more information is available
Lags and Leads
- tool for the process sequencing activities (in Project Schedule Management)
LEAD (overlap): amount of time a successor activity can be advanced with respect to a predecessor activity (Starting the paint work (successor activity) even after partially moving out the furniture (predecessor activity) ).
LAG (delay): Delay in the successor work package or activity (waiting for the paint to dry (predecessor activity) before putting furniture back in room (successor activity) ).
Analogous Estimating (top-down estimating)
- tool for the process estimate activity durations (in Project Schedule Management)
- relies on historical data - get info from previous project done in the past
- quick and cheap estimate but is not very accurate
Resource leveling vs resource smoothing
- tool for the process develop schedule (in Project Schedule Management)
RESOURCE LEVELING: start and finish dates are adjusted based on resource constraints with the goal of balancing the demand for resources. May affect the critical path.
- no one works overtime, resources will be properly allocated, but schedule WILL extend.
RESOURCE SMOOTHING: adjust the activity of a schedule model such that the requirement for resources on a project do not exceed certain predefined resource limits.
- build schedule with resource limitation in mind. NO change in critical path.
Schedule compression: Crashing vs Fast tracking
- tool for the process develop schedule (in Project Schedule Management)
CRASHING (adding resources to a project activity) –> Adds cost, may or may not add risk
FAST TRACKING (activities performed in parallel) –> Adds risk, may or may not add cost
Project Schedule vs Schedule Baseline
- outputs of process develop schedule (in Project Schedule Management)
SCHEDULE BASELINE is part of the project management plan(18 components, 4 baselines,14 plans). It’s not very detailed (only contains project start date, end date, etc.). To change this a change request is needed.
PROJECT SCHEDULE is not part of the project management plan. It’s very detailed with Project network diagrams, Bar charts and Milestone charts. It contains start and end dates for each activity etc. No change request needed to change project schedule!
Critical Path
- Biggest path, highest duration
- no slack, no float, total float!
Total Float/ Float/ Slack vs Free Float
Float/ Slack: time by which you can delay an activity without delaying the ENTIRE PROJECT
Free Float: time by which you can delay an activity without delaying the NEXT ACTIVITY
PERT (Beta), Standard Deviation, Triangular distribution
Pert/ Beta Distribution = (Optimistic + 4*Realistic + Pessimistic)/6
Triangular Distribution = (Optimistic + Realistic + Pessimistic)/3
Standard Deviation = (Optimistic + Pessimistic)/3
