Although the term software architecture is used frequently in today's software industry, its meaning is not universally understood. Avoiding unnecessary complexity will make your system more robust, easier to understand, easier to reason about, and easier to extend. It advises that we should build our functions/classes/modules in such a way that they are open for extension, but closed for modification. When we develop new functionalities, the last thing we want is to make changes to the existing functionality that works and is tested. So that any defects in the requirements or design phase are captured in early stages. Here is a brief summary of each of these principles, as well as practical tips on how to … If you have short and focused functions/classes, you’ll be able to reuse them easily. This allows you to change the implementation whenever you want without affecting the module itself. 5.

The current state of the literature on software development can be caricatured as having two camps, the “scruffy” practitioners (for example, the advocates of the Agile methodologies) and If you have an understanding of the underlying ideas of software development, you will quickly adjust to new techniques. Quality Principle No. Principles, guidelines, best practices, and rules of thumb — they all make your life easier. They understood that the ultimate goal of lean was to relentlessly pursue value over everything else. My passion is for testing, as I believe that good testing practices can both ensure a minimum quality standard (sadly lacking in many software products), and can guide and shape development itself. Agile Testing: 8 Principles, 7 Challenges and How to Master Them. But a lot of times, you may not even need it due to the ever-changing requirements of our software world.

My passion is for testing, as I believe that good testing practices can both ensure a minimum quality standard (sadly lacking in many software products), and can guide and shape development itself. According to Liskov Substitution Principle, if you have a piece of code that uses a Bird object, then you should be able to replace it with a Penguin object and the code will still behave the same. Lean Software Development: The Poppendiecks created Lean Software Development (LSD) by importing lean manufacturing ideas into software development.
