Maybe it’s just me, but I think that some people, especially managers and executives, auto-equate decreasing “cost to create” (CTC) and decreasing “time to market” (TTM) with increasing “quality“. Actually, since they’re always yapping about CTC and TTM, but rarely about about quality, perhaps they think there is no correlation between CTC/TTM and quality.
But consider the polar opposite, where decreasing the CTC and decreasing the TTM decreases quality.
I think both of the above cases are extreme generalities, but unless I’m missing something big, I do know one thing. In the limit, if you decrease the CTC and TTM to zero, you won’t produce anything; nada. Hence, quality converges to zero – even though the first graph in this post gives the illusion that it doesn’t.
Time, Cost, Quality: Pick any two at the expense of the third.
Note: If you’re a hip, new age person who likes to substitute the vague word “value” for the just-as-vague word “quality”, then by all means do so.
Lo and behold! It’s the monstrously famous iron triangle:
Even though all three critical project factors should be respected equally, BD00 put “schedule” on top because the unspoken rule is “schedule is king” in many orgs.
Everyone who’s ever worked on an important, non-boondoggle, project has heard or spoken words like these:
“I’m concerned that we’re exceeding the budget.”
“I’m afraid that we won’t meet the schedule commitment.”
But how many people have heard words like these:
“I fear that our product quality won’t meet our customer’s expectations.”
Ok, so you have heard them, but stop raining on my parade and let’s not digress.
The reason that quality concerns are mentioned so infrequently relative to cost and schedule is that the latter two objective project attributes are easily tracked by measuring the universally accepted “money” and “time” metrics. There is no single, universally accepted objective quality metric. If you don’t believe BD00, then just ask Robert Pirsig.
To raise quality up to the level of respectability that schedule and cost enjoy, BD00 proposes a new metric for measuring quality: the “WTF?“. To start using the metric, first convince all your people to not be afraid of repercussions and encourage them to blurt out “WTF?” every time they see some project aspect that violates their aesthetic sense of quality. Then, have them doggedly record the number and frequency of “WTF?”s they hear as the project progresses.
Before you know it, you’ll have a nice little histogram to gauge the quality of your project portfolio. Then you’ll be able to…, uh, you’ll be able to… do something with the data?
