This presentation criticises many common practices in agile and lean software development and presents some alternatives like a "price per item" model.
be measured in hours (unless we are bodyleasing) Time spent typing in source code is NOT the most significant factor influencing costs or total lead time Even educated guesses are an unprofessional tool when spending other peoples money (compared to concrete measurements)
in an “initial customer workshop” T urned out to be detailed requirement analysis “But we have a column on the board for that, and it isn’t the backlog”
days Only good for a non-binding, rough idea of duration (sprint or release plan) Don’t give it to the customer if they treat it like a promise Never use them for pricing Process should not depend on accuracy of estimates As soon as someone thinks about “improving accuracy” of estimates, that is a smell of misuse
Size is I believe supposed to correlate to development time Development time (and size) is one of the least significant factors influencing an items lead time, and its impact on our throughput
of it What about work that advantages several customers? I have seen people do the poor time consuming solution, because the quick clever one leaves us out of pocket Assumes we want to maximize effort
be billable 20% time not on customer projects? Just like Google! If customer doesn’t want to see pairing, training, non-project meetings or refactoring in the bill, they come out of the 20% Doesn’t suit many roles
throughput for an agreed duration NOT as a percentage of employee hours A little bit more financial risk in exchange for “locking in” capacity especially when maintenance is involved MVP for 50k special offer!
both costs and throughput Can add on extras for other costs of service: e.g. fixed delivery date and expedite Deal is made and price is fixed at queue replenishment
for a service provider to use Customer often doesn’t know what it is worth or is willing to share it Could be good for product companies IF we don’t use imaginary numbers or guesses
and T&M Value-based best but hard Price per item my current favorite http://kurthaeusler.wordpress.com/ 2013/05/20/pricing-and-a-little-bit- about-estimation/
