Sufficient Level of Software Maintainability

In our previous blog post titled “Measuring Software Maintainability”, we explained why it is important to measure the maintainability of software systems and how it can be done. Based on the measurement results, some questions arise. For instance: Is the measured level of maintainability sufficient? Which level of maintainability should be targeted? How far is the measured level of maintainability from the targeted one? By when do we want to reach the targeted level of maintainability? Answering these types of questions is crucial since the answers given determine the decision and actions one must take to properly control maintainability. If you are interested in those answers please keep on reading through this blog post.
