The growth of technology and increasing use of the computers and internet has lead
to the development of many small and large software development companies. There are so many companies available in almost all the cities of India that provide their customers with a wide variety of automated systems.
As per the customer requirement and specification about the need of the new system, the organization shall develop the required system accordingly.
There is a fixed methodology that defines the way the new system has to be designed. There are different types of models that have been defined. These models represent the flow that has to be followed during the development phase. The different types of development methodologies are Waterfall Model, Incremental Model, Prototyping Model and Spiral Model. Each method has its own pros and cons. The organization shall select the model based on the processes and practices.
The period of time for the development is also another factor on which the selection of the process model to be used. Another important factor that is has to be considered is the way the processes are followed. It is based on this processes that the company possesses its reputation. These are called as the Process Improvement models. The different models available in this category are Capability Maturity Model - CMM, ISO 900 and ISO.IEC 15504. Each one of them has its own features and methodologies. CMM is one of the leading and most reputed standards that a company owns. There are 5 levels present in it and level 5 is the highest level that a company can have. Each level has its own set of processes that have to be followed. Based the processed followed,SEI shall issue the appropriate level certificate to the company.
The development process includes the following steps:
Requirement Gathering and Analysis
Planning
Designing
Implementation
Testing
Documentation
Deployment and maintenance
There are a variety of purposes for which the development is done. They are mainly to meet specific needs of a specific business, to meet a perceived need of some set of potential users, or for personal use. The main purpose of the requirement is none other than the automation of manual and paper based system.
There is always a need for better quality control of the product and in order to maintain that quality, set of procedures have to be strictly followed. A systematic approach has to be followed and this is called as software engineering that aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development companies.
