This relates to two ASA-related eGroup postings I've seen recently:
(1) the discussion within the Consulting Section eGroup about working under retainer arrangements.
(2) the announcement of the next (68th) Annual Deming Conference on Applied Statistics, December 2-7, 2012; Atlantic City, NJ. The full program is available at
www.demingconference.com.
All this reminded me of an article by Deming that I happend to see and devour while in the Math-Stat-Physics Library at UNC Chapel Hill 40 years ago. (So long ago that graduate students in those departments were given keys to this library, so we could have 24 x 7 access.)
The article:
Deming, W. E. (1972). Code of professional conduct: A personal view. International Statistical Review, 40(2):215-219. (Y
ou can get this at http://statlab.bio5.org/foswiki/pub/Main/PapersForClassCPH685/Deming-rules.pdf.) Deming's comments on "Fees" follow, but first ...
If you are game, as you read it, consider and respond to two questions quite pertinent to statistical consulting today. Both are based on the assumption that your client requires that you bill by the day. This may also be tied to tallying time against a retainer.
1. Client A's current project calls for you to design, develop, and test a new R function, xyz.r. This is something you will likely re-use in future projects, probably for Client A and perhaps some for other clients. Therefore, you produce something more general and more polished than if you it was merely a "one-shot" tool. xyz.r takes you 3 days to complete. If this had been a one-shot tool, the effort might would have taken 2 days. How many days do you bill/tally at this point towards Client A's project?
2. Two months later, a project for Client B can make use of your xyz.r function. It needs no modification, so instead of taking 3.25 days of programming, you can do it in only 0.25 days. How many days do you tally towards Client B?
Here's the Deming piece. Note the phrase "my fee will be based on my subjective judgment of the relative effort expended on behalf of the engagement." How does this apply to the above questions?
V. Fees
23. The annual fee for regular consultation on a continuing basis will be agreed upon in advance, subject to change by agreement. The client may of course spread payments throughout the year at his convenience. Otherwise, he will receive a bill at the end of every year. With respect to an engagement for a single study, I will send a bill at completion, or possibly at the end of a year if completion appears to be far in the future. I do not itemize time nor regular office expenses for service: my fee will be based on my subjective judgment of the relative effort expended on behalf of the engagement. Irregular expenses such as for travel, or for tabulations done outside my office, are extra, and I may from time to time send a bill to bring them up to date.
24. I do not estimate in advance what my fee might be for participation in a single study. My fees are not competitive. I do not tailor my participation to fit a price. Another point is that the client too often has no idea about the efficiency and economy that statistical theory and techniques can contribute to his study, hence has no basis on which to compare cost against returns. Moreover, neither of us may foresee the complications and duration of a proposed study.
25. In conformity with this last paragraph and with paragraph 2, I will draw up plans for a study and for statistical participation therein only as a professional engagement. I do not make competitive proposals.
26. There will be a fee for an exploratory consultation.
27. I may, at my discretion, engage counsel of another specialist. Such an arrangement requires no clearance from the client except by specific restriction in the interest of confidentiality. Necessity for protracted assistance may call for separate financial arrangements between my client and the specialist. The choice of the specialist will ordinarily be mine.
28. I will make appropriate arrangements at my expense for competent statistical guidance during any prolonged absence that I may elect to take for vacation, meeting, lectures, or disability. If the client elects to engage some other statistician during my absence, he may do so, but at his own expense and subject to my review and satisfaction.
