Maintenance development often becomes the largest cost in the software life cycle.
Why do we spend so much time and money maintaining software and redeveloping functionality after initial launch? Some of the largest contributors are improper requirements or specifications leading to inferior solutions, or worse, solutions that don’t meet their intended purpose. The other major contributors are bugs and defects that make it through testing into the final product.
Why does this continue?
There are many reasons your software development project might not be finished after it launches. If your requirements are unclear, your development teams can easily misunderstand what is expected – leading to iterations or rework to redefine and fix these requirements.
If you don’t have a solid way to verify your requirements or validate system behavior, missing requirements can go unnoticed up until product launch; at that point, rework costs will jump exponentially.
Finally, if your test cycle explodes into far more work and money than initially expected, your budget and resources may dry up before your project is market ready. Launching your project without a complete test cycle could lead to expensive maintenance costs.
What’s the answer?
Don’t let your project get all the way to its launch date before you start thinking about validating requirements. In fact, don’t even start coding until you’ve validated the active requirements – even if it’s for your current Agile sprint. By applying logic-based development and tools, you can ensure your requirements are right from the start.
Throughout the development process, you can make sure your requirements are valid and you have full coverage of test cases with our Direct-to-Test (DTT) software. Our modeling and simulation function allows you to find errors as early as the design stage, and we help you maintain these models for ongoing coverage. With cause effect models, you maintain models rather than individual tests. When a system changes, the analyst studies the affected model and updates it. Then the model regenerates the tests. No more hunting for affected tests, no more expansion of vast test libraries as test analysts ignore old tests.
Send your product to market quicker and with fewer errors by automating testing and script development with our Test Management and Execution (TMX) line. Eliminate typical human errors while freeing up your team’s time to focus on making your product great – not just making sure it works. Our automated regression testing helps ensure that fixing one area of your project won’t negatively affect any other part, while our updated models generate tests that feed seamlessly into TMX, automating the update of the automation code itself. And once your product hits the market, you’ll already have a fully maintained test library ready for the next maintenance cycle, complete with any software changes made along the way.
