Advisory services

What an independent adviser is for, and what to ask them for.

Seven kinds of work a buying committee hires out, each with the situation that calls for it, what to put in the engagement letter, and how the work is normally priced. Then the firms whose own sites state they do it — 4 so far, alphabetical, with the page we read on every one.

01The services

The guidance on each page is Stackmark’s own and stands whether or not our firm list is long. Fees are described as a shape — fixed fee, day rate, retainer, and which contingent arrangements pull against you — never as an invented rate.

02How this directory is built

A firm appears against a service only where its own site names that service. We do not read a general consulting page as a claim to do requirements work, and we do not repeat a claim made only in a press release or a directory listing. Independence is recorded as stated or unstated: 3 of the 4 firms here declare vendor independence on the page we read, and the rest simply do not say, which is not the same as being conflicted.

There are no tiers, no ratings and no paid placement, because nothing here is sold. The list is alphabetical and short on purpose: it grows as we read more sites, not as firms ask to be added.

One gap worth naming: contract and licence negotiation is a service no firm we have read states, so its page carries the guidance and no list.
