As you work with the system, you can begin moving code across the real world interface into a more organized ideal world. When you begin working with a legacy system, the poorly written legacy code might make up nearly all the system. One policy that works well is that, anytime you touch a section of messy code, you are required to bring it up to current coding standards, give it clear variable names, and so on effectively moving it into the ideal world. Over time this can provide for a rapid improvement in a code base, as shown in Figure TBD-3.

CHECKLIST: Refactoring Safely
Is each change part of a systematic change strategy Did you save the code you started with before beginning refactoring Are you keeping each refactoring small Are you doing refactorings one at a time Have you made a list of steps you intend to take during your refactoring Do you have a parking lot so that you can remember ideas that occur to you mid-refactoring Have you retested after each refactoring Have changes been reviewed if they are complicated or if they affect mission-critical code Have you considered the riskiness of the specific refactoring, and adjusted your approach accordingly Does the change enhance the program s internal quality rather than degrading it

Additional Resources
Fowler, Martin. Refactoring: Improving the Design of Existing Code, Reading, Mass.: Addison Wesley, 1999. This is the definitive guide to refactoring. It contains detailed discussions of many of the specific refactorings that I summarized in this chapter as well as a handful of other refactorings that I didn t summarize in this chapter. Fowler provides numerous code samples to illustrate how each refactoring is performed step by step. The process of refactoring has a lot in common with the process of fixing defects. For more on fixing defects, see Section 23.3, Fixing a Defect. The risks associated with refactoring are similar to the risks associated with code tuning. For more on managing code-tuning risks, see Section 25.6, Summary of the Approach to Code Tuning.
Key Points
Program changes are a fact of life both during initial development and after initial release. Software can either improve or degrade as it s changed. The Cardinal Rule of Software Evolution is that internal quality should improve with age. One key to success in refactoring is learning to pay attention to the numerous warning signs or smells that indicate a need to refactor. Another key to success is learning numerous specific refactorings. A final key to success is having a strategy for refactoring safely. Some approaches to refactoring are better than others. Refactoring during development is the best chance you ll get to improve your program, to make all the changes you ll wish you d made the first time. Take advantage of it!

Software architecture: Section 3.5 THIS CHAPTER DISCUSSES THE QUESTION of performance tuning historically, a controversial issue. Computer resources were severely limited in the 1960s, and efficiency was a paramount concern. As computers became more powerful in the 1970s, programmers realized how much their focus on performance had hurt readability and maintainability, and code tuning received less attention. The return of performance limitations with the microcomputer revolution of the 1980s again brought efficiency to the fore, which then waned throughout the 1990s. In the 2000s, memory limitations in embedded software for devices such as telephones and PDAs, and the execution time of interpreted code have once again made efficiency a key topic. You can address performance concerns at two levels: strategic and tactical. This chapter addresses strategic performance issues: what performance is, how important it is, and the general approach to achieving it. If you already have a good grip on performance strategies and are looking for specific code-level techniques that improve performance, move on to the next chapter. Before you begin any major performance work, however, at least skim the information in this chapter so that you don t waste time optimizing when you should be doing other kinds of work.
