apHarmony Software Development Methodology


    Why Our Software Development Methodology Works

    We have a gated quality check approach at each step in our software development process before finalizing a deliverable. We will work independently, or alongside your teams, depending on how you would like to structure the engagement. Each step in the process is clearly defined.

    Below is an in-depth explanation of how we engage with your enterprise at each step in software development.


    Designing a system architecture that meets customer needs and provides scalability

    Our design and UI/UX teams aim to deliver cutting-edge, user-friendly interfaces with software design that results in efficient user experiences and an effective structure for making updates and performing maintenance after deployment.

    We implement a holistic approach in our software development with an eye on the entire SDLC so you have a final product that performs for your specific application and makes sense as a long-term investment.

    Using quality scripted code in languages such as Java, .NET, PHP, and more

    Development can follow a variety of different paths depending on your preference. Internally we often use a waterfall methodology, but we can also use an agile methodology to work more closely with your teams and allow input through the development process.

    We can set deliverable timetables depending on your choice and define the collaborative process that best works with your unique corporate structure and desired objectives.

    QA & Testing the software to guarantee it operates as expected

    With QA, we perform manual and automated software testing throughout the development process before deployment. We'll perform functional testing to ensure proper software function.

    With automated testing, we'll write the necessary test scripts that vary in complexity depending on what we are testing. When we deliver a finished software product, we thoroughly vet it before deployment.

    Deploying the software and making sure it is compatible with the client's hardware and software infrastructure

    Depending on the application and its function within your IT systems, we'll use the best deployment method to ensure easy integration with minimum or no downtime.

    The deployment method will primarily be dictated by how we integrate with your system and your desired rollout process. We'll work together to find the best approach.

    Monitoring the system and support services

    We design our software with Maintenance in mind, so if your enterprise updates its technology infrastructure, you can easily update your software. We'll ensure security updates or corrective maintenance is easy to perform to ensure smooth operations and successful, ongoing integration within your IT infrastructure.


    With many years in the industry, we plan to support all of our customers for many decades to come. As a professional custom software development company, apHarmony aims to ensure that clients are empowered to grow their enterprises.

    When we automate your business processes, we offer high availability and fault tolerance to achieve optimized system performance. At any time, should you require support or assistance from our team, we will ensure that one of our expert software engineers is readily available.

    If we've taken on your project, it means we believe in your Corporate Mission and know we can support your IT infrastructure. We remain committed to your enterprise's software development process from day 1 as we do post-delivery.
