Trying to design a workflow for every possible exception usually creates unnecessary complexity, so option B is correct. ITIL explains that organizations operate in contexts of varying complexity and should avoid over- engineering workflows in an attempt to control every scenario in advance. Highly detailed procedures may appear thorough, but they can become hard to understand, slow to use, difficult to maintain, and ineffective when real conditions change. Instead, ITIL recommends designing processes as practical high-level courses of action, supported by situational judgment and continual adaptation. Excessive detail can reduce agility and make work less efficient without improving value. Strong risk control comes from appropriate governance, visibility, learning, and resilience, not from trying to predict every possible exception. Therefore, over- designing workflows tends to add waste rather than improve performance.
