The PBS is identical in format to the work breakdown structure (WBS), but is a separate entity and is used at a different step in the planning process. The PBS precedes the WBS and focuses on cataloguing all the desired outputs (products) needed to achieve the goal of the project.
The WBS Dictionary describes each component of the WBS with milestones, deliverables, activities, scope, and sometimes dates, resources, costs, quality. According to the Project Management Institute , the WBS dictionary is defined as a "document that provides detailed deliverable, activity, and scheduling information about each component in the ...
Resources and cost are typically inserted into the activities in a WBS, and summed to create a budget both for summary levels (often called "work packages") and for the whole project or program. Similarly, a value breakdown structure will provide the expected value-added of each activity and/or component of the project (or projects within a ...
QA activities aim to validate the software against the predefined requirements, ensuring that it functions as intended. Deployment and implementation: Once the software passes the testing phase, it is ready for deployment and implementation. The development team assists the client in setting up the software environment, migrating data if ...
The project schedule is a calendar that links the tasks to be done with the resources that will do them. It is the core of the project plan used to show the organization how the work will be done, commit people to the project, determine resource needs, and used as a kind of checklist to make sure that every task necessary is performed.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Both human and physical resources, such as software and test instruments, are listed in the example above. The nomenclature is a numbered, hierarchical list of indented layers, each level adds an additional digit representing. For example, the numeric labels (1.1, 1.1.2) make each resource uniquely identifiable. [3]
In software development, effort estimation is the process of predicting the most realistic amount of effort (expressed in terms of person-hours or money) required to develop or maintain software based on incomplete, uncertain and noisy input.
