QUESTIONS WITH SOLUTIONS GRADED A+
⩥ commitment vs accrual vs actual. Answer: -commitment: placement
of an order for work, money removed from budget to represent order
-accrual: work done for which payment is due but not yet made
-actuals: monies already paid
⩥ why does the PM need to be aware of commitments and accruals.

⩥ what is contingency (risk budget vs mgt reserve). Answer: the cost
associated with risk mitigation
-risk budget: allowance for known risk (controlled by PM)
-mgt reserve: allowance for unknown risks (sponsor)
⩥ Differentiate between cost planning for iterative life cycles vs linear
life cycles. Answer: -Linear: scope and quality fixed. Fixed (equipment)
and recurring costs. Funds usually released at decision gates when costs
,are understood and revised forecasts for upcoming phases are available.
Costs approved in line with the business case
-Iterative: cost and time are fixed. Costs are fixed costs and non-
recurring costs (associated with each unit of work). Funding released
more frequently, more interaction with the sponsor
⩥ Explain the role of contingency planning in projects. Answer: Enables
having funds to deal with any residual risk (can include risk budget and
mgt reserve).
⩥ what is the purpose of a cost commitment profile. Answer: -compares
cumulative cost with cumulative revenue
-used to ensure sufficient funds to cover shortfall or may run risk of

planned costs (what I planned to spend: time/money), actual costs (what
I actually paid). Earned Value is what I achieved
⩥ How is Earned Value (EV) calculated?. Answer: %completed *
activity budget (for cost, time)
