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.
James P. Lewis [7] suggests that project scope represents the area of the triangle, and can be chosen as a variable to achieve project success. He calls this relationship PCTS (Performance, Cost, Time, Scope), and suggests that a project can pick any three. The real value of the project triangle is to show the complexity that is present in any ...
The 100% rule states that the WBS includes 100% of the work defined by the project scope and captures all deliverables – internal, external, interim – in terms of the work to be completed, including project management. The 100% rule is one of the most important principles guiding the development, decomposition, and evaluation of the WBS.
The CPM method evaluates the sequence of activities, the work effort required, the inter-dependencies, and the resulting float time per line sequence to determine the required project duration. Thus, by definition, the critical path is the pathway of tasks on the network diagram that has no extra time available (or very little extra time)."
If requirements are not completely defined and described and if there is no effective change control in a project, scope or requirement creep may ensue. [ 4 ] [ 5 ] : 434 [ 3 ] : 13 Scope management is the process of defining, [ 3 ] : 481–483 and managing the scope of a project to ensure that it stays on track, within budget, and meets the ...
A scope statement should be written before the statement of work and it should capture, in very broad terms, the product of the project (e.g., "developing a software-based system to capture and track orders for software"). A scope statement should also include the list of users using the product, as well as the features in the resulting product.
A Sequence Flow is represented with a solid line and arrowhead, and shows in which order the activities are performed. The sequence flow may also have a symbol at its start, a small diamond indicates one of a number of conditional flows from an activity, while a diagonal slash indicates the default flow from a decision or activity with ...
In many industries, such as engineering and construction, the development and maintenance of the project schedule is the responsibility of a full-time scheduler or team of schedulers, depending on the size and the scope of the project. The techniques of scheduling are well developed [1] but inconsistently applied throughout industry.
