Analyze the Requirements: 

• Define the problem to be solved precisely. 
• Verify that requirements are complete. 
• Write program requirements and specifications, including descriptions of program inputs, processing, outputs, and interface.

Design the Solution:

• Develop a plan, detailed and logical, using psuedocode, flowcharts, and diagrams to group activities into modules.
• Create a solution or algorithm for each module
• Test solution modules
• Design user interface

Validate the Design:

• Step test data through the solution design
• Confirm with user that the design is satisfactory and solves the problem

Implement the Design:

• Create the user interface and/or write the code using a programming language or application development tool
• Include internal documentation such as comments to explain the purpose of code statements.

Test the Solution:

• Debug the program, finding and correcting errors.
• Put safeguards into place to ensure desired results
• Implement the solution at the user level

Document the Solution:

• Review and revise (if necessary) all internal documentation
• Complete the external documentation for users.
