About custom software development

How are custom software applications manufactured?

Each custom build software application has to undergo a software development process before it can reach market-readiness.

As such, the following video explains the lifecycle for a software application

Software systems, API's, applications and other technical jargon?

A software application

A software application (or app) is practically a computer program that is designed for satisfying a specific purpose for a specific series of users.

Frontend applications

Frontend applications (or client applications) are applications that have user interfaces. Think of a website, a mobile app or a desktop program that you can work with.

Backend applications

Backend applications are applications that just contain business specific logic (data-centric apps, apis) and that allow other applications to interact with this logic.

An API (or Application Programming Interface) is a good example for an application that exposes business logic towards being used by other applications.

A software system

A software system is practically a collection of applications and apis that work together towards solving a particular set of problems.

Custom software development vs web-design?

If you’re in need of a simple presentational website or a simple e-commerce store then you’re in need of webdesign services that help you build your web experience of top of an existing software platform (such as wordpress or instacart, which offers a lot of software features out of the box)

Custom software development on the other hand represents the manufacturing of software applications that may have unique busines logic (that hasn’t existed before).

Custom developed software systems allow for far greater flexibility with regards to the detail of customisation. 

Creating a web application for orchestrating the workflow of your specific business or manufacturing a software product that is unique to your vision are great examples of what the yield of custom software development is.



How much time does is take to build a custom software system?

În general, the amount of effort that goes into the creation of a custom build software system depends on the number of features that are needed.

As a simple rule of thumb, we have created a simple T-Shirt size for how much time it takes to develop certain systems:

  • S –> Software systems that require a period of 1-3 months to reach the first releasable version
  • M –> Software systems that require a period of 3-6 months to reach the first releasable version
  • L –> Software systems that require a period of 6-12 months to reach the first releasable version
  • XL –> Software systems that require a period of more than 12 months to reach the first releasable version



How is effort estimated for developing bespoke software solutions?

The way in which estimation is performed varies from company to company.

At abac, we make use of an estimation system that involves scoring software features using complexity points and then amounting these complexity points into a total.

By dividing this total against the number of points that a particular team can develop in a certain perioad of time, we then find out the number of weeks needed in order to implement the software solution.
