Software Development Life Cycle (SDLC)

Outsourcing software development work is riding high these days. Many companies and individuals prefer to go for software development outsourcing instead of doing it in-house. Software development work isn’t an easy task as it involves a lot of planning, strategizing and testing. No software is perfect and in full functionality unless it overcomes all the tests. This is the reason why many companies going for software development outsourcing also keep a check on its testing services.

Any company supporting software development outsourcing usually follow a software development life cycle or popularly known as SDLC. The software development life cycle is a set framework preferably used for understanding and developing information systems and software successfully. Nowadays, businesses can easily acquire software in various ways that is from simply purchasing it off the shelf to designing a system tailored to the business’ needs.

This software development life cycle has got many versions and each version carries its own strengths and weaknesses and benefits and disadvantages. Software developer can easily understand how each of these methods affects risk. Many software developers also call Software Development Life Cycle as Classic Life Cycle Model or Linear Sequential Model or Waterfall Method. Each and every software developer has got its own name and definition.

All the software development life cycle includes following activities:

o System/Information Engineering and Modeling- Software are always comprised of a large system, and work usually begins by setting up the requirements for all system elements. Next step is to allocate some subset of these requirements to software.

o Software Requirements Analysis- This stage is also known as feasibility study. In this crucial phase, the development team mainly visits the customer and studies their system.

o Systems Analysis and Design- This is the third phase in which, the software’s overall structure and its nuances are defined. Being in terms of the client/server technology, it requires a number of tiers for the package architecture, the database design, and the data structure design.

o Code Generation- This code generation is performed in a detailed manner, and can be easily accomplished without much difficulty. Programming tools used to generate the code are Compilers, Interpreters and Debuggers.

o Testing- In this phase testing is performed to check the quality and its functionality. Various testing methodologies are available to unravel the bugs.

o Maintenance- Software surely goes into various changes once it is delivered to the customer/client.

Each and every activity has got its own importance and plays a vital role in any software development work. For more information on software development outsourcing, custom software development and Custom Software Development Company just click http://www.softage.ru

Advantages of Custom Software Development for Different Businesses

Every software company strives to maintain a close relationship with its customers by offering customized solutions to their various requirements. Hence, the role of custom software development has grown in prominence in recent times. During a period when business organizations are making all kinds of efforts to become the industry leaders, a stereotypical product with the same age-old functionalities may curtail their advancing chances.

For securing exclusivity in business goals, custom-made or user-friendly software is the most excellent choice at the moment. The major goal of custom software development is to generate an as precise end-product as demanded by the customer. A tailor-made product must be developed after understanding the requisites and preferences of the client.

Customized packages are devised by making use of the most recent technology. They are exclusively developed to satisfy the customer’s business needs. Any difficulty or disliking of the customer that grows out of the building process can be rectified during the formulation of the software with his/her permission and this is the most important advantage of such package development.

As soon as the system is built and delivered to the client, there may be no requirement to make changes to it since it is already developed to perfection. In case of a ready-made package, a business concern may need to carry out a stringent procedure of reconstituting their goals (usually called configuration) so as to comply with the application (which usually turns out to be very expensive since you are dependent on the product provider for development).

Businesses may need to get in touch with the manufacturer of the product for alterations in the presently existing system to match the necessities. This consumes plenty of precious time, energy and financial resources. The tailor-made product is built eyeing specific requirements of the end users and therefore, the complete custom application development costs need to be paid by one client which does not take place in case of the ready-made software.

After the development stage, custom-made system can be implemented right away because the customer hardly requires any modification in the delivered product. The time invested at the time of building custom system may be greater. However, this must not be an impediment in selecting a customized package for an organization’s particular function. However, the question arises why the software development life cycle goes up during the building phases.

This is because of the fact that the procurement of the ideal tailor-made product demands strict inspection to ensure proper comprehension, analysis and precise execution of thoughts into the final product. In addition, ready-made package may result in lower levels of expenses than custom software development; but, the high expenditure in the latter case takes place only due to profound research and mounting customer demands since the end product needs to be an output sought by the client.

A committed custom application development company always communicates with the client through teleconferencing, telephone, electronic mail or chat, regardless of being onshore or offshore. This is the most crucial activity since the requirements can be transmitted and understood regularly and no possibility for ambiguities is brought forth. Customized software demands frequent communication before as well as after the development stage.
