GpiI-2C Identifying software project stages, tasks and deliverables Aim Breakdown the estimated effort into tasks. To do that, we shall identify: project deliverables, project stages and project tasks. GpiI-2C Identifying software project stages, tasks and deliverables

GpiI-2C Identifying software project stages, tasks and deliverables Breakdown Methods: By Processes Different conceptual stages What?, How?, Development, Test ... by Products We identify different products that will make up the required system. Example: Sales, Stock Control, ... GpiI-2C Identifying software project stages, tasks and deliverables

It will be focused to an only product. Reasons: Project Size - failure risk. Coordination costs. Incremental development. It is logic that the “strategic direction” is the one in charge to identify the needed products for the enterprise. GpiI-2C Identifying software project stages, tasks and deliverables

Work Breakdown Structure (WBS) method of representing, in hierarchical manner the components of a process or product. GpiI-2C Identifying software project stages, tasks and deliverables

Graphic representation of WBS. GpiI-2C Identifying software project stages, tasks and deliverables

List representation of WBS. 0. Accounting project. 1. Specify needs 1.1. Study present system. 1.2. Add New characteristics. 2. Analyze Accounting. 2.1. Study Processes. 2.2. Study Data 3. System Design. 3.1. Data Base Design. 3.2. Programs Design. 4. Coding 4.1. Scheme development. 4.2. Programs code. 5. Test. 5.1. Unit test. 5.2. System test.

GpiI-2C Identifying software project stages, tasks and deliverables WBS Numbers help to locate tasks in the WBS. Nodes are read as: “is contained in” Developing a WBS. Identify the top of the WBS. Partition each component into 72 The lowest level are the task in a project GpiI-2C Identifying software project stages, tasks and deliverables

Software project Deliverables. Concept: "Products interchanged among clients and developers during the software project development". Relatives: To the object. To the project management. GpiI-2C Identifying software project stages, tasks and deliverables

It has to be defined a minimum set of deliverables. They provide: the component set that will make the product once the development ended. The means to measure the progress and quality of the product development. The needed materials for the following stage. Usually the enterprises have their own deliverables check list. GpiI-2C Identifying software project stages, tasks and deliverables

Breakdown in stages of a system development. Since time ago, many enterprises classify the kind of tasks achieved in a project and analyze the effort dedicated to each of them. We will see same examples provided by Martyn A. Ould, and one an other from HP. GpiI-2C Identifying software project stages, tasks and deliverables

Breakdown the software project into tasks. By deliverables (More than a week?) Two horizon levels. Immediately Half term GpiI-2C Identifying software project stages, tasks and deliverables

Equipment focusing to identify tasks by activities. Implying to developers. Use their knowledge and experience. The worker perception. Submission to the goals Responsibility GpiI-2C Identifying software project stages, tasks and deliverables

Usual ways to identify tasks to a deliverable. To document, to find out or research, To Organize, to write documents, To check, to verify, to review To Revise, to update documents, To deliver, to finalize Other ways: Breakdown provided by employed technician GpiI-2C Identifying software project stages, tasks and deliverables

Usual tasks in a software project. Same enterprises have their own check list with a tasks list, were you can find the more important tasks to be considered. GpiI-2C Identifying software project stages, tasks and deliverables

Some ideas on the software project breakdown. Make the tasks in order to be done by one or two persons in one or to weeks. Try to have independent tasks, don´t cut natural process. Worry about people communications. Reuse code, but it cost time to. GpiI-2C Identifying software project stages, tasks and deliverables
