Sorry this is a long one.
I have to push a big smile to BAJR - I too love being a curator. As I see it, we have two main responsibilities. The first is to ensure that the archaeological resource is protected. And that is more often than not through the planning process, though it comes up in other areas too (countryside schemes, statutory undertakers, metal detectors whatever) to be defensible to a court of law, if required. The second is to make sure that everyone else knows what you've found, and to re-assess that as and when.
It is totally correct that at present no one polices the police. Other than the aforesaid court of law. But what developer is going to go to court to argue you did too little? My group has argued the death over becoming an RAO. But until the IFA says what standards they would require of an RAO Curatorial group, and how and by whom that will be monitored, we won't do it. Most of us are in the IFA anyway, so have already signed up to that code of conduct.
I personally hate watching briefs and try to use them as little as possible. If I think there's archaeology, I get trial trenches done. Saves hassle in the long run, and gets things dealt with better. However, as I work in a predominately urban area, these are seldom done before a planning application has been determined.
I do use strip map and sample exercises, but the canny consultant would be wise to still ask for an evaluation first. What if there is someting requiring preservation in situ, or a massive amount of archaeology is uncovered? That could potentially scupper some pip pipelines/roadworks, and the way english heritage is presently funding things, they are unlikely to fund unexpected discoveries. And that can lead to impossible compromise.
And (finally) to pick up on something Peter said. Have you noticed on BAJR that the pay and requirements for curators is decreasing rapidly? I think there was one DC job advertised recently for as little as ?15k (please correct me if I'm wrong). Local authorites are constantly devaluing the role and value of a curator. The good ones are decamping to better paid consultancy work. And the new ones have less and less experience (sometimes they are only advertise with 3 years excavation work) and the chance that this new crop will stand up and shout, call developers on bad practice and show some mettle, will, I fear, get even more rare.
But this has deviated even further from the original single context topic - may start a new thread (if I can figure out how to do so....
).
