I stated that if they are not taking data and applying a metric then I'd start by getting them to do that. That is the only way that I know of to start making accurate estimates." Hold on. You did not refer to a productivity metric. You imagined that there is a productivity metric. In news:5be89e2f.0107221953.8a52@posting.google.com you actually said "[..] I was assuming that management could accurately predict the level of effort needed to complete projects and had meaningful productivity metrics in place. [..]". I have not read all of your posts in your "Ada The Best Language?" thread but I have not seen you actually describe properly nor name any of these metrics which you claim would be useful.<< First of all I did look for the productivity metric that I posted as a strawman and I couldn't find it in that thread. Apparently you're trying to pin me down to a metric that is useful for all organizations which I can't do. The point is that the current thinking in software engineering is that processes that can make reliable schedules are accomplished by collecting data and determining metrics for estimating future productivity.

What does this mean? I've already acknowledge that I think Ada 95 is a better programming language than C++. I'll try to make this clear. My original response in this thread was based on an assumption of what I consider to be rational management. I don't think that I'm the only one who shares those opinions. If management is acting irrationally I would start by trying to get them to act rationally. This is the same approach that is taken in other disciplines when analyzing and discussing the decision making process. If you have another definition of rational management then please bring it to the forefront. >> (Russ) wrote in message > news:... > > I work in an environment dominated by C/C++, and I would like to > > recommend Ada for a safety-critical application that is about to be > > initiated. > > EXCELLENT, you're probably going to have an incredibly hard sell [..]" ) > when productivity studies extolling Ada are not winning you over, perhaps > you would like to look at the "accu-general: Making estimates about > work" thread from this month on the accu-general emailing list of the > Association of C & C++ Users ( HTTP://WWW.ACCU.org/ ; archive available to > members only; I highly recommend membership of the ACCU). > > From the first of these accu-general posts: > "[..] > > How do you all approach the task of making estimates of how long it will > take you to do your work? > > [..]". > > A not necessarily representative but not the only response of this sort: > "When I'm spending time & effort on having realistic estimates, I try to keep > track of how long previous tasks took.
