1 Plan and design
Understanding the problem: decide on the nature of the
problem; break the problem into manageable sections; consider how each
section can be programmed
Preparation for programming: define input screens and
output screens/report; draft out definitions of any data which is to be
stored; identify constructs to be used; identify objects to be used; break
the program into modules
2 Write the program
Learn and use the language: the construct and definition
statements used by the language; work with different kinds of variables,
operators, conditionals and procedures; set properties of objects at design
and run time; respond to events
3 Test and modify
Test: plan tests and predict results; create test data
for normal, extreme and abnormal testing; test event handling such as
response to mouse clicks; evaluate the test results with reference to the
specification
Modify the program: modify the program as a result of
testing
4 Document
User documentation: user friendly; instructions for
starting, using and quitting the program; incorporate screen dumps and other
graphics to explain specific operations such as on-screen menu choices
Technical documentation: instructions for installation;
annotated program listings; program specification; diagrammatic
representation of the modular structure; notes of calculations and any
special feature
