Writing computer code just comes easy for some people. While so many struggle to learn a given development language, the gifted developer has the ability to master many. Unfortunately, many code writers have difficulty conforming to a strict process that promotes well-designed and readable code.
They are often convinced that providing software that performs a desired function or task is the end game, and while this is certainly one aspect of development, there are processes that are used to create systems that are more forgiving to user input, make more efficient calculations, and allow for enhancements to be implemented in future cycles. The best code writers are most always those who follow certain principles of software engineering.
One of these principles is referred to as concern separation. This principle deals with the need for humans to work from within a restricted context. Functionality that includes data manipulation can usually be divided in to two major pieces. One of these is the raw functionality. The other is the process or processes that actually protect data. These two aspects of code should be treated individually whenever possible. This results in more efficient algorithms and better code optimization.
Keeping these pieces separate leads nicely to something known as modularity. This principle enhances separation concern by building on the practice of keeping functionality separate where possible. Working with smaller pieces of code helps improve its readability. It also fosters easier creation of unit tests and more efficient debugging.
Another standard, while perhaps not as technical as modularity but equally valuable, change anticipation can make a huge difference between poor code and quality programming. Code writers are often able to deal with abstract concepts with no regard for how a user may use their software. They frequently focus only on the manipulation of data.
Over time, developers can gain a better understanding of how their software is used, and clients become more aware of the nuances of the software they are using. Code enhancement for a growing project can benefit greatly by anticipating the potential for a change in requirements over time.
While many engineers view generalization as an afterthought, the user experience and the quality of the code relies on it heavily. The year 2000 problems provide an excellent example. The inability of most software to accept four-digit years was a severe limitation as many will recall. Looking ahead and recognizing where certain code restrictions can become problematic is crucial.
Incremental development is an especially valuable principle. There is value in smaller projects, however larger ones can place a heavier reliance on this style. This is a development process that breaks a project down into small increments. Code writing may be limited to a certain sub-set of use cases at a time. This is an excellent way to handle debugging as well as the addition of functionality.
Consistency is key. This is not exclusive to engineering of course, however following a certain standard or code-writing style provides a plethora of benefits. Organizations without code consistency find it difficult to debug their software and can experience pain each time an engineer needs to be replaced. A consistent and streamlined process benefits all aspects of a company, and software engineering is no exception.
In today’s world, a software engineer must be more that code-savvy. He or she must also be aware of and adhere to certain principles of software engineering. The most efficient developers are those who recognize the need for quality code that provides the user with a friendly, like the that are also powerful and even intuitive tool.
