Software development process

It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.

The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application.

A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" is a particular instance as adopted by a specific organization.

[citation needed] For example, many specific software development processes fit the spiral life-cycle model.

The main idea of the software development life cycle has been "to pursue the development of information systems in a very deliberate, structured and methodical way, requiring each stage of the life cycle––from the inception of the idea to delivery of the final system––to be carried out rigidly and sequentially"[2] within the context of the framework being applied.

This stage typically involves engaging in thorough discussions and conducting interviews with stakeholders to identify the desired features, functionalities, and overall scope of the software.

The development team works closely with the client to analyze existing systems and workflows, determine technical feasibility, and define project milestones.

Regular communication between the development team and the client ensures transparency and enables quick feedback and adjustments.

The development team assists the client in setting up the software environment, migrating data if necessary, and configuring the system.

Agile processes fundamentally incorporate iteration and the continuous feedback that it provides to successively refine and deliver a software system.

The lack of extensive pre-planning generally allows software to be written much faster and makes it easier to change requirements.

These stages are repeated iteratively; further development results in "a combined business requirements and technical design statement to be used for constructing new systems".

It has been widely blamed for several large-scale government projects running over budget, over time and sometimes failing to deliver on requirements due to the big design up front approach.

It provided emphasis on a key area many felt had been neglected by other methodologies: deliberate iterative risk analysis, particularly suited to large-scale complex systems.

It is a set of principles and techniques that Basecamp developed internally to overcome the problem of projects dragging on with no clear end.

Rapid Application Development (RAD) Model
The activities of the software development process represented in the waterfall model . There are several other models to represent this process.
