The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. [1] A critical path is determined by identifying the longest stretch of dependent activities and measuring the time [2] required to complete them from start to finish.
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)." [25]
One thrust of critique has come from the critical chain developers and followers (e.g. Eliyahu M. Goldratt and Lawrence P. Leach), [10] as opposed to critical path method adherents. The PMBOK Guide section on Project Time Management does indicate Critical Chain as an alternative method to Critical Path.

Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining of software applications.It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.
One component of software design is software requirements analysis (SRA). SRA is a part of the software development process that lists specifications used in software engineering. The output of the analysis is smaller problems to solve. In contrast, the design focuses on capabilities, and thus multiple designs for the same problem can exist.
