Estimating, Risk and Issue Management Flashcards
What are the four common approaches to estimating ?
Delphi
Analogous
Parametric
Analytical
Risk is an important part of estimating why?
We most allow for the uncertainties that may have an effect on our project
An estimate is ?
An educated guess
An estimate should have a ________ and the accuracy of estimates should ___________.
Range
Improve over time
As we understand more about the project and it’s requirements and discuss and engage with experts and do the work we would expect the range of inaccuracy to reduce this is called ?
Estimating funnel
Estimating funnel is a ______ of the increasing levels of estimating ________ that can be achieved through the phases of the lifecycle.
Representation
Accuracy
An estimate is a forecast of the ?
Probable time or cost of completing work
A subjective estimate
A vague and inaccurate estimate
Early stage of a project
Analogous estimate
Once more information and the requirements are known a comparison can be made between previous jobs and the current one
Parametric estimate
Once everything is finalised
The work and material for each work package from the WBS are measured
Analytical / bottom-up estimate
The cost of each work package up through the levels of the WBS to get a cost estimate for the whole project .
This provides a very accurate estimate
Optimistic estimates can lead to ?
Working late or missing deadlines
Estimates should be checked to determine whether they represent ?
Effort or duration
Effort represent the ?
Cost of the work
Duration represents ?
The time it will take to complete the work
For a network only duration is required for the network to determine the ?
Critical path
Risk management = a key activity for ?
The project management team
Risk management has four key steps ?
Identification of the risk
Analyse there probability and the impact
Response and decide if they need to mitigated if so how and implement that mitigation
Closure , where we close the risk
Risk are normally identified through ?
Brainstorming
Through a risk workshop or part of a planning workshop
Workshops have a facilitator or a agenda. The agenda consists of several risk areas such as :
Technical
Operational
Economic
Environmental
Social
Political
The risk must be expressed in terms of the :
Cause
The area of uncertainty
The effect
Once identified the risk must be analysed in terms of ?
Probability and impact
Probability describes ?
How likely the risk is to happen ; usually at some sort of percentage score
The impact describes
The impact on the project objectives of the risk occurs ; the assessment is made on the basis that we are not not taking any mitigating action.
