Project Management System

A SDLC system refers to the phases or stages that comprise the system development. Just as humans and biological systems move from conception through to ceasation, with each stage characterized according to its successive stage, system, business processes and software can also be characterized this way. This term has been popularized by the software development industry but its use applies to all manner of activities and industries. The following article examines a SDLC system.

The initial stage of the SDLC system is the feasibility and research stage which focuses on intelligence gathering in an attempt to define the variables and factors that comprise the system or the desired solution. This can include identifying the customers needs and establishing deliverables. It can also include SDLC system analysis if it involves the examination of existing businesses or applications. If there are stakeholders involved, discussion takes place to put forth all the issues and considerations for discussion and investigation. This usually results in a scope or system definition that is used in each stage of the SDLC system.

The next stage of the SDLC system is referred to as SDLC system design. This is where the proposed solution is modeled or developed. It can include the examination on dependent variables such as existing hardware, software or infrastructure. No actual build or development takes places. The new system requirements are defined in light of any identified deficiencies in the existing system together with specific proposals for improvement.

The development stage of the SDLC system (SDLC system development) is where the actual commencement of work takes places. It is the transference of the scope and system design into reality. In construction based projects, this would be the actual development of the structure itself. For software based projects, this is where the developers begin the build phase of the software application.

The testing phase of the SDLC system is where quality control takes place. For software, this is bug testing, userbility testing and requirements analysis. For other industries, it can include stress testing or inspection to determine whether the initial solution meets the original system objectives. Feedback from this stage results in the iterative refinement of the system before the solution is released to the stakeholders.

In some projects there is a maintenance phase as part of the SDLC system. This is to keep the solution functioning in accordance with its intended use and to modify any variables for system improvement.

There are several different SDLC methodologies which are adopted by industry. These include the waterfall model, rapid application development, joint application development, the spiral model, build and fix, synchronize and stabilize and the fountain model. These models all apply to SLDC system processes which comprise a formalized way to manage the stages of the SDLC system. In reality, many organizations adopt a hybrid based model which is usually an adaptation of existing models tailored in accordance with organizational requirements and company culture.
