LOW‐LEVEL DESIGN After your high‐level design breaks the project into pieces, you can assign those pieces to groups within the project so that they can work on low‐level designs. The low‐level design includes information about how that piece of the project should work. The design doesn’t need to give every last nitpicky detail necessary to implement the project’s major pieces, but they should give enough guidance to the developers who will implement those pieces. For example, the ostrich racing application’s database piece would include an initial design for the database.

Even after all that time, there was a decent chance I misunderstood something and the change added a new bug. Then I got to remove the change and start over. I worked on another project that included tons of comments. Probably more than 80 percent of the lines of code included a comment. They were easy to ignore most of the time, but they were always there if you needed them. After we transferred the project to the company’s maintenance organization, the folks in the organization went on a JBGE bender and removed every comment that they felt wasn’t absolutely necessary to understand the code.

You should break the project into the large chunks that handle the project’s major areas of functionality. Depending on your approach, this may include a list of the modules that you need to build or a list of families of classes. For example, suppose you’re building a system to manage the results of ostrich races. You might decide the project needs the following major pieces: ➤ Database (to hold the data) ➤ Classes (for example, Race, Ostrich, and Jockey classes) ➤ User interfaces (to enter Ostrich and Jockey data, enter race results, produce result reports, and create new races) ➤ External interfaces (to send information and spam to participants and fans via e‐mail, text message, voice mail, and anything else we can think of) You should make sure that the high‐level design covers every aspect of the requirements.
