Example from MIL-HDBK-881, which illustrates the first three levels of a typical aircraft system [1] A work-breakdown structure (WBS) [2] in project management and systems engineering is a breakdown of a project into smaller components. It is a key project management element that organizes the team's work into manageable sections.
The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method.
Budgeted cost of work scheduled – (BCWS) the approved budget that has been allocated to complete a scheduled task (or Work Breakdown Structure (WBS) component) during a specific time period. Constructability – is a project management technique to review the construction processes from start to finish during pre-construction phase. It will ...
A project network diagram is a graph that displays the order in which a project’s activities are to be completed. Derived from the work breakdown structure, the terminal elements of a project are organized sequentially based on the relationship among them. It is typically drawn from left to right to reflect project chronology.
The concept has similarities with the deliverable-oriented work breakdown structure (WBS) decomposition which is used in project management and systems engineering to break down a project into smaller components in a tree structure that represents how the work of the project will create the components of the final product. Resources and cost ...
The dependencies between the activities; Logical end points such as milestones or deliverable items; Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process ...
Project management: project planning, resource planning, project costing, work breakdown structure, billing, time and expense, performance units, activity management Customer relationship management (CRM): sales and marketing, commissions, service, customer contact, call center support – CRM systems are not always considered part of ERP ...
A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD): A regular version of sequence diagram describes how the system operates, and every object within a system is described specifically.
