TAILIEUCHUNG - Applied Software Project Management - LESSON 3: ESTIMATION

The project manager must set expectations about the time required to complete the software among the stakeholders, the team, and the organization’s management. If those expectations are not realistic from the beginning of the project, the stakeholders will not trust the team or the project manager. | LESSON 3: ESTIMATION Applied Software Project Management 5/13/2020 10:42:33 PM REVIEW stakeholder Project manager team of software engineers Business analysts or requirements analysts Designers and architects Programmers Testers 5/13/2020 10:42:33 PM Vision and Scope Document Problem Statement Project background Stakeholders Users Risks Assumptions Vision of the Solution Vision statement List of features Scope of phased release (optional) Features that will not be developed 5/13/2020 10:42:33 PM WHAT IS ESTIMATION? The project manager must set expectations about the time required to complete the software among the stakeholders, the team, and the organization’s management. If those expectations are not realistic from the beginning of the project, the stakeholders will not trust the team or the project manager. 5/13/2020 10:42:33 PM ELEMENTS OF A SOUND ESTIMATE To generate a sound estimate, a project manager must have: A work breakdown structure (WBS), or a list of tasks which, if completed, will produce the final product An effort estimate for each task A list of assumptions which were necessary for making the estimate Consensus among the project team that the estimate is accurate 5/13/2020 10:42:33 PM 5/13/2020 10:42:33 PM WORK BREAKDOWN STRUCTURE Define project scope by listing all of major sub-projects or deliverables on a project The decomposition of a WBS Represent unique work Clearly defined duration or a total effort Discrete enough Responsibility can be assigned to a person or group 5/13/2020 10:42:33 PM WBS WBS family tree diagram Tracking cost 8/80 rule No work package should be fewer than 8 labor hours or more than 80 labor hours 5/13/2020 10:42:33 PM ASSUMPTIONS MAKE ESTIMATES MORE ACCURATE Team members make assumptions about the work to be done in order to deal with incomplete information Any time an estimate must be based on a decision that has not yet been made, team members can assume the answer for the .
