In such a creeping scope environment you should probably tell them your estimate is likely to be 80-200% of the final cost.

Don't forget to factor in supplier timescales. For example I was originally hired to do a 3 month contract @ my current place setting up some Solaris gear. The gear only turned up 4 months later...... If you're having to deal with 3rd parties, you need to add a lot more padding....And the lord said unto John; "come forth and receive eternal life." But John came fifth and won a toaster.Comment

Originally posted by youwhut View PostI wasn't entirely clear. When I talk about solution 1 and 2, these are options. Option 1 is the intial idea because they thought (haha) it could be done in the 4 weeks remaining on my contract. Option 2 has become the desirable but will take much longer.
If option 2 is desirable for cost saving/revenue reasons (it must be, surely?) do make a big deal about it and give the client some figures.+50 Xeno Geek Points

I agree with the poster who said give a range. I'd make the low end of the range my "real" estimate (i.e. not the "best case") and the top end = real + 30%Comment

Originally posted by Platypus View PostNope, commercial. You tell client it will cost between X and Y, then they expect to get it for X even on a T&M project.

Tender in haste, repent at leisure. Myself I'd have declined to tender on the limited info presented here. I'd have put forward a "best guess" plan with key deliverables, milestones, projected end date and offered a day rate for the duration. It's upto the client then. Anything else would be too risky without a detailed spec to tender against from the client.Public Service Posting by the BBC - Bloggs Bulls**t Corp.
