What is software construction?

A note after reading the book "Code Complete", all the copyright are belong to the author of this book.




    this diagram illustrate the the activities software construction will include, it focused on coding and debugging, but also includes detailed design, unit testing, integration testing and other activities.

    It's just a high level view of the construction activities, but what about the details? Here are some of the specific tasks involved in construction:

• Verfying that the groundwork has been laid so that construction can proceed successfully.
• Determining how your code will be tested.
• Designing and writing classes and routines
• Creating and naming variables and named constants.
• Selecting control structures and organizing blocks of statements.
• Unit testing,integration testing , and debugging your own code
• Reviewing other team member's low-level designs and code and having them review yours.
• Polishing code by carefully formatting and commenting it.
• Integrating software components that were created separately.
• Tuning code to make it faster and use fewer resources

   wow! so many activities included, if you've worked on informal projects, you might think that this list represents a lot of red tape, If you've worked on projects that are too formal, you know that this list represents a lot of red tape! It's hard to strike a balance between too little and too much formality.
 
  Here is reason why construction is so important:

• Construction is a large part of software development, tipically takes 30-80 percent of the total time spent on a project.
• Construction is the central activity in software development
• With a focus on construction, the individual programmer's productivity can improve enormously. the productivity of individual programmers varied by a factor of 10 to 20 during constructoin.
• Construction' product, the source code, is often the only accurate description of the software. documentation is always out of update.
• Construction is the only activity that's guaranteed to be done.
• Construction
