&gt;Gap gets this right.<p>I did consulting for them and they hired aforementioned retail consultants for this job. I will admit I initially thought it was stupid, having been a wise retail manager at the age of 17 at one point in my life (and did a lot of level-1 tracking of sales and A&#x2F;B testing, even back then!). But when these retail consultants showed me their data and how it was formatted... it was unbelievable. Most of what I experienced in retail were these nebulous and stupid ideas that were conjured from the ether from my direct managers and general managers and the like. While I&#x27;m sure not all the information I saw trickled down to employees, it was truly enlightening and gave me zero room to argue particulars with how they were studying and implementing retail flow, checkout, and return procedures.
