First of all, the problem is that pharma company expectations are dreamed up by people in New Jersey who have no idea of the actual environment in today's offices, resulting in completely unrealistic expectations of what reps should be able to do in the field.
Secondly, no, sales results are not subjective. Every company knows exactly what their market share and sales volume are. True, pod selling situations do cloud the issue, but you cannot go by customer evaluations like GSK is trying to do. The problem with this model is that reps are incentivized to get the providers to like them, so as to get a favorable review from the provider. Thus, they are not going to press the provider to allow some time when they come up to the rep and say, "can I sign anything for you?" Now, they might do that if it is a DM ride-along, but otherwise, no way.
Also, "how many actual calls you make" in a day does not, in and of itself, correlate with sales results. What's important is how many persuasive calls you make per day. If you can have 4 or 5 truly persuasive calls in a day, I say that is really good.
And with the bunching up of providers into groups, each of which have their own specific protocols for seeing reps, "what time you get in the field" no longer means much either. You seem like you think it's still the 1990s. Most group offices allow a certain number of reps to come in from, say 9:30-11am, or 1:30 to 3:30pm.
I think this whole thing is just a politically correct way of trying to change the public's(and perhaps politicians') perceptions of pharma companies. I personally make no apology for the pharma industry being a for profit enterprise.
