SMART is a goal-setting framework commonly used in IT project management to define clear, trackable objectives. SMART stands for specific, measurable, achievable, relevant, and time-bound. The guideline that best matches SMART is creating criteria that can be used to measure success, because measurable goals require defined indicators and metrics to determine whether the goal has been achieved. In IT projects, measurable criteria might include performance benchmarks, uptime targets, defect rates, delivery dates, cost limits, or user adoption percentages. Option A aligns more with the collaborative emphasis found in frameworks like CLEAR. Option C relates to emotional connection, which is also a CLEAR characteristic. Option D mentions limiting scope and time, which partially resembles being time-bound and achievable, but the statement most directly and uniquely reflects SMART is the measurable requirement. Without measurable criteria, teams cannot objectively evaluate progress or confirm completion, which can lead to scope creep and unclear outcomes. Therefore, the SMART guideline represented in the options is creating criteria that can be used to measure success.
