Software Development Life Cycle – Introduction Model Stages and Advantages

What is the Software Development Life Cycle (SDLC)?

SDLC or Software Development Life Cycle is essentially the process or phases of a model or methodology, which software engineers and developers follow in developing an application or software. In simpler words, it is a process consisting of a series of planned activities for planning, creating, testing, deploying and maintenance of software.

SDLC is often referred as software development process, as it consists of all tasks, which needs to be followed while developing an application or software. SDLC is followed within IT development companies to develop, alter, replace or enhance the performance of the software. ISO/IEC 12207 is an international standard for SDLC, which ensures high quality of the newly developed software. It also helps IT development companies in improving the overall quality of their software development services.

What are the major SDLC Models, followed in the IT Industry?

There are various SDLS models, which are currently followed in the IT Industry. Often referred as ‘Software Development Process Models’, all the process models follow unique software development steps, ensuring 100% success of the development projects.

The major software development life cycle models are-

  • Waterfall Model
  • Iterative Model
  • Spiral Model
  • V-Model
  • Big Bang Model

Other related models are Rapid Application Development (RAD), Prototype and Agile Models.

The advantages of choosing an appropriate Software Development Life Cycle (SDLC)-

  • Increased Product Quality
  • Increased Development Speed
  • Improved Client Relations
  • Improved Tracking & Control
  • Decreased Project Risks
  • Decreased Project Management Overhead

What are the different stages of SDLC?

Stage 1:

Planning and Requirement Analysis

This is the most important stage in the SDLC. This stage needs input from the customers, sales team, industry experts, a marketing team and their survey reports. After which, senior business managers and developers of a software development company plan the project approach and the development model.

Stage 2:

Designing

After the analysis of requirements and finalizing the Design Document Specification (DDS), the product architecture is designed by an expert team. This architecture has to stand upon various parameters such as budget, time, product robustness, risk assessment and design modularity, after which it is considered for the development.

Stage 3:

Development

The actual development of the software or application starts at this stage. The team of engineers and developers follow the coding guidelines set by the organization and use different tools for code generation. The programming code is generated as per the details documented in the DDS. The developers use different high level programming languages as per the requirement.

Stage 4:

Testing

In this stage, the final product goes through a pre-defined road of testing, where defects or bugs in the product are reported and then fixed by the developers. This stage ensures that the final product meets the highest quality standards, which are accepted worldwide.

Stage 5:

Deployment

At this stage, the final product is deployed at the client base. At times, the software is integrated with the client’s current application and database. All the deployment and integration works are done under the guidance of expert software engineers and developers.

Stage 6:

Maintenance & Support

Most of the reputed IT development companies also provide complete maintenance and technical support, post deployment of the final product at client base.

Business Benefits of Custom Software Development

All businesses and organisations will typically need some form of software during their lifecycle. The types of software utilised by most companies range from applications that will enable better management of key organisational functions – Human Resources, Finances and Accounts, inventory and stock and even running projects, to more specific items of software that have a key purpose such as Content Management Software for use on company websites. Although these software applications can be purchased “off the shelf”, there are many business benefits that can be associated with choosing custom software development.

Custom Software Development is created for you

Developing custom software is a bespoke, made to measure process, which means that any applications and software programmes created as a result of the process will be entirely made for your company and its individual needs and requirements. Basically, a piece of custom made software is flexible and has the potential to fulfil your specifications meaning that it is easy to use and can be deployed throughout your entire organisation. Instead of having to make do with a ready made software programme or application, with customised software you can be sure that what you will receive will be entirely fit for purpose. There are also significant financial benefits that can be associated with custom made software despite it costing a little more to purchase than off the shelf packages. Software applications that have been made for you don’t require any licence fees, so you can distribute them across your entire organisation without needing to pay extra.

Custom Software Developers will work with your Company

When creating software designed for your company, custom software developers will design and code it to integrate properly within your organisation. The software won’t just help you achieve what you need it to achieve, it will be rich in features and tools that will make it usable by the people who will be operating it. With a piece of custom software all the requirements of your company will be considered, and developers will meet these both in the way that they develop the software and the after care that they provide properly. Although some training and support is available with off the shelf software to a certain extent, with custom made software your developers will continue to work with and support your company whether that’s through training staff members in the use of the software or providing maintenance and technical help to remedy any errors that might occur in the software.

Customised Software is Safe and Secure

The ready made software packages available to businesses and organisations today are certainly a lot more secure than the ones that have been developed in previous years, however they don’t compare to the security levels of customised software. Because customised software has been created for your company it will only be usable by individuals in your company. When you purchase custom software you will be given administrator rights to the software ensuring that you can change and alter user profiles and passwords to be in accordance with your own internal data protection policies. Customised software used on the web is also a lot harder to hack than standard, off the shelf software, and you can be sure that a reputable custom software developer will work hard to keep your application or programme and the data it contains as safe and secure as possible.

Customised Software is Adaptable

Ready made software is designed to be adaptable and flexible, meeting your company’s needs and requirements both now and in the future. Even if you need a few different software programmes to accomplish organisational tasks, a custom developer will be able to integrate the different processes that you need into a single, usable application. Custom software is also much more likely to be cross-platform suitable, so you can be sure that when your company goes mobile you have the software that will support it.

Offshore Software Development Trends in 2012

The Drivers of Offshore Software Development

The offshore Software development trend has been around for a while now and many IT as well as non-IT companies all over the world are engaged in outsourcing their software development needs to offshore software development centers due to the various benefits provided by the outsourcing process. One of the leading drivers of this trend has been the reduced cost factor associated with the outsourcing process in general. During the credit crunch caused by the global financial crisis, companies were focused on reducing costs and the offshoring process helped reduce overheads and improve the outsourcing company’s bottom line. In other cases, non-IT firms with no or minimalist IT departments also outsource their software development requirements as developing such software in-house often tends to be cost prohibitive. The lack of expertise of a company with regard to use of a specific set of software tools/platforms necessary for developing one or more applications is another driver commonly associated with such outsourcing. Such non-IT firms include industries from a wide range of sectors including but not limited to transport and logistics; education; healthcare as well as banking and financial services. Each of these sectors and even companies within the same sector, however, require unique solutions suited to their own needs. Many organizations also follow a blended approach by mixing outsourcing with in-house expertise to develop the necessary solutions.

Leading Offshore Software Development Priorities

Many companies across the world are currently engaged in developing new software products/applications according to the requirements of clients. New software development is expected to account for a major portion of the software revenue in 2012 and beyond. A close second is the requirement for companies to upgrade their existing software application by integrating new technologies/modules into their already deployed solutions. In 2012, the integration aspect is expected to gain more ground as new technologies/applications increase the benefits provided to organizations by the current solutions. The main benefit of such integration is the reduced deployment time for the company as well as the decreased cost of development as compared to in-house development. The consumerism of IT (CoIT) trend is also beginning to affect the market as users demand a superior user experience delivered by these solutions. As the market for solutions which go beyond delivering basic functionality expands in 2012 and beyond, the focus of many an offshore software development company is expected to shift towards using new technology to develop better User Interface (UI) and graphics for solutions, which were deployed earlier in the enterprise. Such development is often classified as custom software development, is also expected to witness robust grow among offshore development companies in the year 2012 as well as the recent future driven by increases demand across multiple industries.

Other key functional areas for offshore software development operations include performance improvement-based software development as well as the continued maintenance and support for existing solutions. As more and more companies deploy software solutions in order to gain a competitive advantage in the intensely competitive market, the number of performance enhancement contracts between organizations and offshore software development firms is expected to increase. Another software development area expected to witness rapid growth in 2012 is the development of dedicated mobile apps. The focus on developing apps for mobile is expected to continue in the recent future driven by increased enterprise mobility requirements and the growing adoption of BYOD (bring your own device) philosophy by enterprises. A related area which is forecast to grow in 2012 is the development of cloud apps for use by the enterprise as well as the development of improved security solutions to ensure superior data security and compliance with all existing regulations of data protection.

Leading Deployment Areas for Software developed at Offshore Locations

The requirement of software developed by offshore centers is not limited to any specific industry therefore the list of probable deployment areas is quite large and expected to grow further in 2012 as technological advancements open up new application areas. However, the development of data storage/management/Business Intelligence software is expected to be the leading business area for offshore software developers in 2012. Such solutions are deployed by a wide range of industries to cope with the explosion of digital data and facilitate an informed decision-making procedure, which is expected to propel continued growth of the Business Intelligence solutions market. Other leading deployment areas for software developed at leading offshore locations include applications required by the financial and healthcare sectors as well as solutions deployed for managing processes/projects and applications which are necessary to facilitate enterprise-wide networking and communications. Other areas of interest for these companies in 2012 include applications for facilitating the deployment of e-commerce, CRM, content (document) management platforms, online analytics etc. Overall, in 2012 and beyond, the industry is expected to witness robust growth as companies increase their IT expenditure with the intention of gaining a competitive advantage in the market.

Development Platforms Preferred by Outsourcing Enterprises

Among the available software/application development platforms currently in use today, internet/web-based development platforms are expected to dominate the offshore development market in 2012. However, enterprise application development platforms and SaaS/Cloud-based platforms are also expected to witness growth as more organizations issue contracts for new solutions based on these emerging platforms. The emergence of BYOD is also expected to result in the development of various mobile platform-based applications in the recent future, while desktop application and embedded platforms are expected to witness only marginal growth in 2012 due to the perceived restrictions inherent to these platforms.

Leading Offshore Destinations around the World

Over the years, India has traditionally been the leading offshore software development destination for firms based in the US and Europe. This situation is not expected to change in 2012 even though emerging players are expected to partially erode India’s current lead in the global offshore development market. Emerging markets, where organizations are currently outsourcing their software development requirements include Central and South America mainly Brazil and Mexico; various countries in Eastern Europe; China; countries in the Asia-Pacific region such as Philippines, Indonesia, Vietnam; as well as Russia and Ukraine. Over the next few years, these emerging players are expected to provide stiff competition to software development centers based in India. The key criterion for competition among these offshore development centers is forecast to include overall cost, development quality, project/client handling procedures and the total development time required. However, even in the face of such challenges, India is expected to retain a dominant position in the global offshore software development market in the year 2012 as well as in the recent future.
