A functional analysis defines the functions and interfaces required to implement a solution to a business issue. It comprises the following steps:

• Defining the business issue (current situation);
• Identifying functional requirements (expected outcome);
• Identifying processes involved in the issue;
• Analyzing gaps between the current situation and the functional requirements that have been established;
• Identifying opportunities for optimizing the processes involved;
• Selecting software;
• Analyzing gaps between the established functional requirements and available functionalities;
• Elaborating hardware and software architecture;
• Evaluating implementation costs.
