The final elaboration phase deliverable is a plan (including cost and schedule estimates) for the construction phase. At this point the plan should be accurate and credible since it should be based on the elaboration phase experience and since significant risk factors should have been addressed during the elaboration phase.
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development.It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
[3] [19] Crowder's system, which he called "intrinsic programming", was better known as "branching programming" on account of its multiple-choice alternatives. Much better known was the other style of programmed learning, as proposed by the behaviourist B.F. Skinner. Skinner made some very effective criticisms of traditional teaching methods. [23]
The waterfall model is a breakdown of developmental activities into linear sequential phases, meaning that each phase is passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. [1] This approach is typical for certain areas of engineering design.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.

Construction phase – focuses on program and application development task similar to the SDLC. In RAD, however, users continue to participate and can still suggest changes or improvements as actual screens or reports are developed. Its tasks are programming and application development, coding, unit-integration and system testing.
