As we identify customer and supplier requirements for a SIPOC we are urged to use the RUMBA approach which stands for _____________, Understandable, Measurable, Believable and Achievable.

Question

Options

• ARational
• B(un)Resistable
• CRelatable
• DReasonable

• B
  4% (1)
• C
  4% (1)
• D
  92% (24)

Explanation

Reasonable is the correct answer because RUMBA is a quality checklist used in SIPOC analysis to validate that requirements are well-defined - the "R" specifically stands for Reasonable, meaning requirements must be realistic and sensible within the given context.

Why the distractors are wrong:

• A (Rational): While "rational" is close in meaning, it's not the designated term - RUMBA uses "Reasonable" as its standard word, and precision matters in process frameworks.
• B ((un)Resistable): This has no meaningful connection to requirements quality; it's a distractor designed to seem clever.
• C (Relatable): "Relatable" is a colloquial term without a defined role in business process or quality management vocabulary.

Memory tip: Think of RUMBA as a dance - before you can dance, the choreography (requirements) must be Reasonable, Understandable, Measurable, Believable, and Achievable. If any step is unreasonable, nobody can follow the routine. The word "Reasonable" also naturally pairs with "Believable" and "Achievable," as all three address feasibility - which helps you remember they belong together in the same acronym.
