Software development refers to the analysis, design, development, testing, deployment and maintenance of software. Our software developers adhere to up-to-date development coding standards and best practices to ensure the production of secure, reliable, maintainable and transferrable software. Throughout the different stages of software development, our extensive client engagement will provide you with the peace of mind and satisfaction that your business needs and requirements will be met.

A software launch is the distribution of a major version of the software application. It may be either public or private and generally constitutes the initial generation of a new or upgraded application. The support phase in software development follows the launch or deployment phase. This phase focuses on aspects such as amendments related to error corrections or enhancements as a result of changing customer requirements. It ensures the software continues to perform and work as expected to meet current and future business needs. Software upgrades will occur as often as required.

The main difference between generic and custom software is that in generic software development, the software requirements are specified and owned by the product developer. As it is designed for many customers, it can only meet the clients’ general requirements. For custom software development, the specification is owned and controlled by one client and cannot be used by any other businesses. It is designed to cater for all the client’s current business needs.

There are many reasons why choosing custom software is highly beneficial for any business:

  • Cost savings
  • Investing in your business
  • Productivity gains
  • Competitive advantage

Refer to Why choose a custom software solution? Here are four reasons why. (intergy.com.au) for more details.

The client will have full ownership (intellectual property rights) of the custom software code. Intergy will supply the client with the entire source code upon completion of the project and payment of the agreed project price.

The custom software process life cycle includes several stages starting typically with planning and requirement analysis followed by design, build/development, testing and deployment with an ongoing stage of maintenance and support.

At Intergy, we follow either an Agile or the traditional Waterfall software development model depending on the nature of the project and client requirements. The Agile model is used when the requirements change often (with the software being delivered in phases or sprints) which is characterised by frequent communication between the clients and development teams. The Waterfall model is used on projects where the scope is well defined, and when the client is seeking some clarity around timeframes and budget. Then we can follow a more structured software development process, in which progress is seen through the delivery of the various phases including initiation, analysis, design, development, testing, deployment and maintenance. It is relevant to note that in many cases we start with a Waterfall approach for the first release, and then move to an Agile approach after that.
