If you are relying on GPS positions, then with AGPS I believe it is accurate to about 8 meters, and cellular GPS is about 600 meters and GPS itself is about 10 meters.<p>So basically, a driver doesn&#x27;t have to go up your driveway. He just needs to pass by your house. And there is no way for UPS to ever know, unless they have video but I&#x27;d never allow them to video on MY property.<p>UPS are stupid if they think that such micromanagement is good for their business. There problems appear to be:<p>1. They set unrealistic deadlines,<p>2. They don&#x27;t treat their workforce with much respect. This leads to unintended consequences - like for example you not receiving your package, or higher levels of car crashes, or people jay walking, or increased injuries from strain and fatigued workers.<p>Honestly, in a system that tracks this many variables, it doesn&#x27;t take much for an employee to figure out how to game the system! An example is given in the article - the employee who buckled the seatbelt and then sat with it behind his back!<p>This is honestly a manifestation of an idea that Bruce Schneier made some time back - the more you add restrictions or monitor someone, the more they will attempt to bypass your systems in order to get their job done (or more likely - meet your metrics). The employee does it because the risk of losing their job for non-performing is less than the penalty for getting caught. [1]<p>3. This is a great way to unionise your workforce and get strike action taken against you. This level of micromanagement tends to be favoured by control freaks and power crazed managers who misuse the data. It also causes problems when the data is followed without knowing a more holistic view of the system. I&#x27;ve seen thus in call centres - the best ones I&#x27;ve seen have had no KPIs, the ones with strict call time KPIs have led to dreadful customer service as the entire goal of the operator is to get you off the phone, not resolve your problem. In that situation, they tell the customer literally anything in order to keep them happy but make them hang up.<p>Giving this level of metrics to lower level managers is a bad idea, instead I truly believe it should be kept with people who know how to handle data and interpret the results correctly.<p>---<p>Footnotes:<p>1. <a href="https:&#x2F;&#x2F;www.schneier.com&#x2F;essays&#x2F;archives&#x2F;2009&#x2F;08&#x2F;people_understand_ri.html" rel="nofollow">https:&#x2F;&#x2F;www.schneier.com&#x2F;essays&#x2F;archives&#x2F;2009&#x2F;08&#x2F;people_unde...</a>
