Crucial Stages of Application Software Development

Any software is created by several methodologies and programming codes put together. Application software gives life to the machines. But while making use of electrical equipment, we never think much about its internal working process. The software available these days are of two major types.

1. System software: The system software has been designed in a way in which it offers a common interface between the person who is using it and the hardware of the system.

2. Application Software: The application software is programmed in such a way that it is capable enough to assist the person in multi tasking. It assists in bringing solution to different problems, helps to customize ‘n’ number of graphics, texts as well as numbers.

Various types of application software are available in the market including entertainment software, infrastructure software, content management software and many more. There are specifically defined stages for the development of application software. The process of it is mentioned below.

  • Defining the requirement: During this stage, the authorities of the company define the requirements of the client and plan out the design so that the product can be made accordingly. During this stage the budget and the deadlines of the project are also decided.
  • Designing: The designing part is the heart and soul of any software. This is because the smooth working of the software depends on the quality of the design. The software is usually created and developed by the software developers based on the plan which is accepted by the client as well as the organization. There are times when the company hired for the software development fails to integrate the features that have been asked for. In these cases they have to invest in debugging.
  • Testing the software: Testing is important to ensure that the system works smoothly and the programs developed are capable and efficient of working in any situation. During the testing process, the testers manipulate the programs to check if there are any loopholes.
  • Putting the software into practice: When the application software development is done and it is void of any flaws, it is put into practice by the client. Even during this stage, if there are any errors in the system, they can be checked and corrected.
  • Servicing: The firm providing application and software development should also be ready to provide regular servicing and maintenance to the clients whenever necessary. Customer support should also be provided by the hired firm so that the client queries and doubts can be cleared.

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.

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.

Software Development Explained

Most of us don’t even know what software development means. Let me explain. Basically it means that someone works to develop or create new software, usually to meet the needs of business owners, for the personal use of the user, or to supply the potential needs of a client.

Developing new software usually is perceived as ‘computer programming’ to most people. That is only part of the process. There is much research that has to be done in the development of new software programs. This often involves many modifications, engineering and re-engineering, and maintenance of the finished product before it is declared ready for use by the general public.

The software developer is usually someone who’s main concern is with the many facets of the process. Their involvement is often guided by lead programmers during the developing of the software programs. It often takes a long time and no small amount of luck to develop a program that is finally free of glitches typically found in new software programs.

Programmers are the people who typically write the source codes, and the developers are often involved in many other aspects of the process, including, but not limited to specifications, designs, implementations and maintenance to name a few. Certain employees may have a single responsibility in just one of these phases of development, yet in a smaller place of business, it might be that just one employee would take on all of the tasks involved.

Companies take different approaches to how they develop software. Often it is regimented and structured when it pertains to business software. Other companies develop the software one step at a time. However the approach, there are some of the same combinations of methodologies used in the development of new programming.

A methodology in software language means a framework is developed that will structure the development process of new informational systems. Many frameworks have been used over a period of years, and what might be right for one project may not necessarily work for another. This is why new frameworks are being developed and used more often.

The same strategies are employed in both large and small companies. All involved employees would meet to discuss requirements, and proposals and recommendations are usually made at this time. The design work is worked out and clarified. Anything that needs to be updated is done now, and the developers can begin the job or working on the system. Once all this is completed, the system is delivered. Security measures are tested, and any glitches or bugs are worked out to everyone’s satisfaction. The system is deemed complete and is now ready to be distributed and used.

So, there you have it. The capsulized version of how new software is developed, and a brief discussion on who does the work that brings new and exciting developments to the software field. Assuredly there is a lot more to it than what I have discussed, but I think I have included enough information to give one a general idea behind it all.
