Facilitated Application Specification Technique (FAST for short) is used to gather requirements for a specified software application.
Usually, during the FAST technology session, for the sake of effectiveness, it is recommended that you adhere to one or more of the following conditions:
- Both customers and developers participate in the meeting dedicated to the definition of requirements for a given IT product.
- There must be specific meeting rules that are followed by both parties. One should bring an open and positive atmosphere to the meeting for it to be successful.
- The meeting is managed by an intermediary. Such an intermediary can be a customer, a developer or outsider, accepted and trusted by both parties.
- To document requirements it is common to use tools such as lecture posters with racks, wall-mounted indicator panels or plain ribbon paper.
- The purpose of the meeting is to identify the tasks or needs of the customer, propose a solution, discuss various approaches and define a set of requirements.

It is highly recommended that a debugging specialist attend this meeting, or even the FAST meeting procedure somewhat be simplified so that elements of static testing can be used during this meeting. JAR technology particularly favors the built-in static testing, which is called “supportive support” in the JAR terminology.
One of the types of information that can be extracted during the requirements identification activities is the agreement between the customer and the developer regarding the priorities of the requirements. For example, each requirement can be assigned to one of the following categories:
- The most important requirements.
- Highly desirable requirements.
- Desirable but not necessary requirements.
Due to this prioritization the development plan gets simpler. For example, you can create a plan that puts the main emphasis on the implementation of the most important requirements in the first version of a software product, the implementation of desired requirements in the second version and all the others in the third version. Likewise, the testing team can begin developing tests for the highest priority requirements in the first instance. This type of incremental supply or supply of versions is often used in cases where compliance with the time schedule is critical.
