‘Bad’ Code and its Consequences

  1. 1. www.extentia.com | Confidential ‘BAD’ CODE AND ITS CONSEQUENCES
  2. 2. www.extentia.com | Confidential What is ‘Bad’ Code • Not readable • Badly organized code and poorly structured control flows; carelessly named classes; architectural and design issues; poor attention to detail on issues of scalability, security, and more • Not testable • Poor testability that can be easily observed from the simple activity of measuring the time spent on testing/debugging vs the time spent on development, as the project progresses • Hard to extend • Even trivial features take a long time to deliver, pointing to the problem of extensibility – happens because of the combined effects of lack of readability and testability
  3. 3. www.extentia.com | Confidential What Results in ‘Bad’ Code • Pressure to deliver more in less time • Forces the developers to take shortcuts, making the code hard to maintain and extend • Developers and testers blame the business guys • For not allowing enough time for writing ‘good’ code or refactoring ‘bad’ code • Software development managers • Give up on the engineering excellence aspect of Software Development Life Cycle (SDLC) • This results in serious consequences and high costs to be borne at later stages
  4. 4. www.extentia.com | Confidential Consequences of ‘Bad’ Code • The general perception of the quality of the output begins to deteriorate as the team spends more and more time in fixing bugs than in actually creating new features • In extreme cases, adding features becomes virtually impossible with seemingly unrelated parts of the system failing due to the addition of a feature or, worse – fixing an earlier bug
  5. 5. www.extentia.com | Confidential Consequences of ‘Bad’ Code • Costs of adding features increases at an alarming rate with each delivery cycle • Adding more people becomes difficult, as they take a long time to come up to speed; sometimes, new team members are blatantly scared to touch large parts of the code, due to the fear of failure • Customer complaints increase, putting intense pressure to write an even worse code – to keep fixing the issues quickly
  6. 6. www.extentia.com | Confidential How to Avoid ‘Bad’ Code • Managers and businesses must not accept code that has the characteristics of ‘bad’ code • Software development teams must be open to adopting automated and instrumented systems • For measuring the quality of code • Managers must keep a close watch on the primary output of the team – the code • Practitioners-programmers, designers, architects, and testers need to • Acquire a high level of self-discipline and professionalism in the way the code is designed, written, and tested
