That’s not a witty acronym, and it doesn’t hide the fact that this user goal is not specific, measurable, actionable, relevant or trackable. It fails all five criteria because it fails the first: specificity. A good user experience has many facets, and without targeting a specific aspect of the page or product experience, there’s no action (strategy and tactic) to address it. If a goal is not actionable, then it has no reason to exist because there is no end towards which effort and action can be directed. Similarly, if the goals are not measurable, then there is no way to gauge the successes or failures of our actions, and subsequently no way to understand the product’s performance over time.
