The Basic Methodology of Software Development Services

Software development is a technically complex process which goes through various stages during the whole development procedure. The concept is termed as software (S/W) development life cycle (SDLC) and involves various stages of (S/W) development. To successfully offer software development services, organizations should define a development methodology that suits the requirements of the project. Different projects may require different methodologies therefore software development service providers must evaluate the project requirements first and then formulate the strategy for the software development life cycle.

Most of the software development service providers have a pre-defined methodology that is implemented while developing a software. The process gets a little modified according to the project requirements but the essence of the project development procedure remains the same. The basic stages of software development are as mentioned below:

Requirements Specifications: The first and foremost step while developing software must be gathering the requirements of the project. The organizations must start with analyzing the feasibility and the requirements of the project. Some questions that must be clarified in this phase are:

What are client’s expectations of the project?

What would the user want in the software?

Is the project technically feasible or not?

The above questions, along with many more, must be answered and properly justified before software development service providers move any further.

Design: This stage involves development of an outlay for developing the project with all the little details included. The project requirements are evaluated and an implementation strategy for achieving these requirements in the form of a software is formulated. The designing phase is divided into two categories i.e. system design and component design. The system design is design of the software as a whole where questions like how the individual components will interact with each other are answered. The component design phase, as the name suggests, deals with the planning for each individual component.

Implementation: The components are actually created in the implementation phase. The design layout created in the previous phase is implemented and converted into a machine language that the computer can understand and respond to. Programming languages such as C, C++, C#, Asp.Net, PHP etc are used according to the project requirement to achieve the best possible results. The source code and database are created in the implementation phase. Accurate and effective designing of the software is essential for a successful implementation of the software.

Testing: The testing phase usually starts after the components are created but in some cases the software development service provider can start the testing along with the implementation phase. This methodology may require a little more effort and time but the end solution is void of any discrepancies or errors as they are detected and removed as soon as a component is developed.

Installation: The components of the software are combined together and the completed software is installed and executed on a computer system. If all the previous phases have been performed expertly then there will be no problem in the installation phase. A thorough testing is again recommended after installing the software to make sure that the end solution is working as desired.

Maintenance: It has been noticed that almost every software goes through changes and modification after it is completed. This may be due to some new requirements, overlooked features or the change in the business strategy. This requires constant evaluation and maintenance of the software.

Most of the software (S/W) development service providers follow the above described development methodology for creating softwares. It is the basic methodology of S/W development services. Once the software is completed and delivered successfully, the task of the service provider does not end. A professional S/W development company will offer maintenance services to insure a smooth and well functioning solution to their clients.

Dragging Software Development into the 21st Century

Companies spend billions of dollars every year on developing their own software applications or purchasing complex enterprise software applications. This includes not only the cost of software, but the hardware infrastructure required to support the software as well. Rather than spending this money on software development, a company should put it to better use to improve the core business of the company. That is, the company should be focusing on what it is that they are really in business for rather then being distracted by software development.

Current software development practices for enterprise applications often result in products that are too expensive to develop, acquire, implement, integrate and then maintain. The typical software development cycle starts with a base product that is developed and subsequently sold, if external, or delivered, if internal, to a client. If the base product is lacking in functionality, then additional modifications must be made to the base product, adding to the cost of development. Once modifications have been completed, the implementation and integration phase starts. This phase has high costs associated with it; usually surrounding customization in order to get the software to interface with existing legacy systems. Finally, annual maintenance and service fess are charged, which usually do not include future upgrades. Clients are frequently less than happy with the results. The software development entity is often unaware that the client is not happy until the next development cycle is well under way, at which point it is too late and too expensive to address the problems. This results in an endless cycle where the software developed for a client continuously lags behind the client’s actual needs. Financial and human resources, which could be used too much greater effect elsewhere, are absorbed into a cycle that could be avoided altogether.

One of the highest costs involved in software development is the cost of developers. Over the past few decades computers have automated most industries. Ironically, the one industry that has not benefited from automation is the software development industry. Writing software is still a manual process involving monotonous and repetitive tasks. Techniques, such as code reuse and code generation have been developed over the years to reduce the workload. However, developers are inherently resistant to change and to anything they perceive as being able to “replace” them. Either they do not trust someone else’s code, or they think they could write better code themselves. For whatever reason, developers wind up reinventing the wheel project after project and billing for that work. Since developers are reluctant to utilize tools and techniques in their own development, they become their own worst enemy. The computer is the greatest tool ever invented and developers, the ones that make this great tool work, are reluctant to take maximum advantage of it.

If there is an industry that should be automated it is the software industry. All business applications perform the same basic functions and they interact with a database the same way, doing inserts, updates, queries, deletes, etc. They interact with the user through a user interface allowing the user to input and retrieve data. The internal plumbing that ties everything together is the same. What makes an application unique is the business rules, logic, and workflows (how the user moves through the application). Ideally there would be a tool that would “create” these common features and help “manage” the unique parts.

A tool is needed that would allow a developer to focus on the “what” or the rules and workflows instead of the “how” or the plumbing. A tool is needed that would take care of the monotonous and repetitive tasks. These laborious tasks are precisely where a computer excels. This tool has been created and it is ready for those who can accept giving up total development control and let the computer do what it was invented to do: expedite commerce.

Introduction to Software Development

Software is a part of the computer system which allows or enables the hardware to operate. Computer software can be classifies as system and application software.

System software includes the operating system and other utilities which help in the smooth functioning of the computer and other applications in it.

Application software includes computer programs and related documentation that accomplish end-user data processing tasks. These are software developed for the end users for tasks like production control, payroll, inventory, word processing etc.

Software Development

It is a series of processes systematically undertaken to improve a business through the use of computerized information system. Software development has two major components, Systems Analysis and Design.

Analysis specifies ‘what’ the system should do, that is it sets the objective and Design stated ‘how’ to accomplish this objective. System Analysis is the process of studying the current system by a set of procedures which help to gather and interpret facts, identify the problems and use this gathered facts to improve the current system. The process of developing a new system with detailed concentration on the technical and other specifications that will make the new system operational is system design.

Software Development Life Cycle (SDLC)

It is a sequence of events carried out by analysts, designers and users to develop and implement an information system. The activities are carried out in different stages. The phases are Preliminary investigation (feasibility study), Determination of system requirements (analysis), Design of system, Development of software, System testing, System Implementation, System Maintenance. In reality these phases can overlap.
