Various software development phases are described.

2. Program Development
• Tells your computer to dp particular job in
desired manner.
OR
• List of instructions in specific language to tell
the computer to do job in sequence.

3. Phases of program development
Whenever any problem has to be converted
into a program then following steps are to be
followed:
• Analyzing the problem
• Designing the solution
• Coding the solution
• Testing the solution
• Documenting the solution

4. Development phase

5. Problem Analysis
• Complete definition in written form
• Understanding the written definition
• Defining the input facts and identifying the
source
• Produce desired results
• Major areas involved:
Input, Process, Output, Storage

6. Program Design
• Breaking the project into small pieces and
designing logic for each part.
• Describes desired features and operations in
detail, including screen layouts, business rules,
process diagrams, pseudocode and other
documentation.

7. Program Coding
• Translating the program design into
appropriate computer programming language.
• Approach:
– Top to bottom
– Bottom to top

8. Testing Programs
Examine the output screen and determine what
is wrong?
• Check for alignment problems with output
information.
• Check for missing information
• Verify computation information and check
formula
• Take different set of test data and run the
program.

9. Documentation
• User documentation – User Manual
• Programmer documentation
– Copy of original written specifications
– Copy of input, output, process and storage analysis
– Copy of source code, flowcharts, pseudo code or
other designs if used.
– Printed copy of input facts used to test program
– Printed copy of all possible output reports or screens.
