Splitting the requirement_slide_share
The document discusses requirements analysis by comparing requirements to atoms. It states that requirements have basic elements like atoms have particles, with the 5 main elements being behavior, condition, rationale, quality, and procedure. Each element drives and constrains the others. The structure of a requirement is depicted, with the behavior at the center and the other elements connected to it to form the overall requirement.

- 2. What do RequirementsLook Like? • Have you ever wondered what a requirement looks like? • What they look like on the inside. • If we could split one open, like an atom, what would we see? The New Business Analyst 2014-10-20 ©2014 PJM Limited and The New Business Analyst. All rights reserved 2
- 3. Think Building Blocks • The atom is the basic building block of matter. • Atoms are made up of even smaller things known as particles. The New Business Analyst • The requirement is the basic building block of a solution. • Requirements are also made up of smaller things known as elements. 2014-10-20 ©2014 PJM Limited and The New Business Analyst.

- 4. It All Startswith a Behaviour • Every requirement must do something. • What it does, how it does it, when it does it and so on, are the elements of the requirement. • Like an atom, requirements are expressed with structure.

- 6. The Elements ofa Requirement 1. Behaviour – Defines a range of actions in combination with itself The New Business Analyst and it’s environment. – It is the response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary. (Source: Wikipedia) – Drive and constrain all elements within its structure. 2014-10-20 ©2014 PJM Limited and The New Business Analyst. All rights reserved 6
- 7. The Elements ofa Requirement 2. Condition – A material implication or consequence. – Realis mood, a mode of grammar, which refers to The New Business Analyst the inflection of a sentence, in this case a statement of fact. – Conditions drive and constrain behaviours. – Conditions also drive and constrain procedure. 2014-10-20 ©2014 PJM Limited and The New Business Analyst.

- 8. The Elements ofa Requirement 3. Rational – The organisational or stakeholder need behind The New Business Analyst the requirement. – Ideas that should operate according to reason and logic. – Rational drives and constrains the behaviour. 2014-10-20 ©2014 PJM Limited and The New Business Analyst.

- 9. The Elements ofa Requirement 4. Quality – Qualities are distinctive attributes or The New Business Analyst characteristics possessed by the behaviour and other elements of the requirement. – Qualities drive and constrain and are driven and constrained by other elements within the structure. 2014-10-20 ©2014 PJM Limited and The New Business Analyst.

- 10. The Elements ofa Requirement 5. Procedure – An established way of proceeding. – Steps needed to accomplish the rational. – Defines how the behaviour will act. – Procedures are driven and constrained by other The New Business Analyst elements within the structure. 2014-10-20 ©2014 PJM Limited and The New Business Analyst.
