Chapter 1: Introduction
Software Construction

What is Software Construction?
Software Construction is a group of activities that go into
software development (See the following figure)
 Construction focuses on coding and debugging but also
includes some detailed design and unit testing.
 Construction comes after architectural design and before
system testing.
 Other common terms for construction are implementation
and programming.

A few of the specific tasks involved in construction:
Verifying that the groundwork has been laid so that
construction can proceed successfully.
 Designing and writing routines and modules
 Creating data types and naming variables
 Selecting control structures
 Finding and fixing faults and errors
 Reviewing other team members' low-level design and
code and having them review yours
 Polishing code by carefully formatting and commenting it
 Integrating software components that have been built
separately
 Tuning code to make it smaller and faster

Non-Construction activities include:
Requirement analysis
 Software architecture
 User-interface design
 System testing
 Maintenance

Why is Software Construction Important?
Construction is a large part of software development.
Construction typically takes 30 to 80 percent of the total
time spent on a project. Anything that takes up that much
project time is bound to affect the success of the project.
 Construction is the pivotal activity in software
development. Analysis and design are done before
construction so that you can do construction effectively.
System testing is done after construction to verify that
construction has been done correctly. Construction is at
the center of the software development process.
 Construction's product, the source code, is often the
only accurate description of the software.
 Construction is the only activity that's guaranteed to
be done no matter how rushed or poorly planned a
project is you can't drop construction.
