Anybody with limited knowledge of programming can write code. The difference between good code and bad code is in the architecture, coding conventions, reusability, readability, scalability, performance and maintainability of the computer program.
Defining a high performance architecture that is scalable, reusable and maintainable is the most critical phase of a software project. Our system architects produce elaborate system designs and data structure diagrams to help the developers program within predefined boundaries. The architecture of the system is largely governed by the choice of the technology framework but it is important to ensure that the system is created using the guidelines provided by the framework.
To ensure maximum readability of a computer program, several measures must be taken by the developers. These include the naming conventions for classes, functions and variables, style and frequency of commenting, guidelines for reuse etc. Over the years our coding guideline documents for various technology platforms have evolved into a very sophisticated set of standards and we take every step to ensure that our developers follow these standards while writing the code.
It is important to understand the meaning of scalability in software development. The number of users for any system can dramatically increase over a period of time. Having an architecture that allows the system to scale with the increase in load is extremely important. Increase in the number of users will have a negative impact on system performance if the system is not designed to be scalable. It takes years of experience working with mission critical systems to know all the loop holes that must be closed to produce a scalable system that performs well during higher load times.
In software development the same output can be generated in many different ways. Choosing the implementation that ensures the highest performance comes from experience and following well defined performance testing guidelines. Faster systems not only produce a better user experience, they also save a lot of time over an extended period of usage. A number of load tests can be designed to test the performance of a system under different scenarios. Our developers are skilled in using various performance testing tools and we impose strict measures to ensure that every project goes through a thorough performance testing phase.
Sustaining engineering refers to continued support and enhancement of a system following the release to production. A well designed system with proper technical documentation is lot easier to maintain compared to a poorly developed program with little or no documentation. Maintainable system code requires a good architecture with proper coding guidelines and these must be defined at the beginning of the development phase. Maintainability is one of our main goals during any software development project.
