Module 11: Managing System Implementation

During the implementation phase you will develop the applications, test the
system, install the hardware and software, and evaluate the system once
complete.

There are tools for each systems development approach. Structured
development relies on DFDs and structure charts. Object-oriented methods use a
variety of diagrams, and there are generic tools to help translate the system logic
into properly functioning program modules. In an agile development the customer
creates user stories that describe required features and priority levels.

To measure a module’s scope and processes use Cohesion. Modules that
perform a single function or task have a high cohesion, which is a desirable trait.
Coupling measures the relationships among modules. Independent modules are
loosely coupled, which is desirable. Cohesion and coupling concepts are used in
structured development, but also are applicable to object-oriented development.

There are four steps in creating a structure chart. You review the DFDs;
programmers perform desk checking, code review, and unit testing tasks;
systems analysts design the initial test plans, which include test steps and test
data for integration testing and system testing; integration testing is performed for
systems that interact; and, finally, system testing is completed.
