SPECTRE Task Estimator
 

Five-Minute-Task Time Estimate Worksheet

One of the great unsolved problems in software development is the task of estimating time required for a software project. Lots of different reasons have been given for this, ranging from programmer ego to software development complexity. Rather than focusing on causes or theoretical approaches, I herein offer a practical guide to improving time estimates for the worst-case scenario, the dreaded Five Minute Task.
(For your convenience, the first two answers have been filled in.)

Preliminary Estimate

How long will the five-minute task take? 5 minutes

Detailed Worksheet

For each item below, please provide your best estimate for the time required for completion. DO NOT enter zero for any field!

basic changes/development:

5 minutes

deal with the compile-time errors you failed to anticipate:

 

deal with an obscure compiler error you've never seen before:

 

figure out why it dumps memory before executing first line of code:

 

figure out why it still dumps memory, even though you fixed the problem:

 

total time of other staff in helping you with previous item:

 

completely rewrite it to work around obscure system or compiler bug that could not be solved even with other peoples’ help:

 

deal with additional compile-time errors introduced by rewrite:

 

figure out why it dumps memory again:

 

it seems to work; now fully test all new/changed functionality by hand:

 

correct problems found:

 

code for obscure error conditions or user input exceptions that you didn't think of until just now:

 

add some features that would be easy and relevant that you didn't think of until just now:

 

compile again:

 

test again:

 

write/update program documentation:

 

write/update user documentation:

 

rewrite documentation that you lost from the power failure:

 

install software:

 

test the installed version:

 

figure out why installed version doesn't work or works differently than before:

 

fix install problem:

 

install documentation:

 

update source control area:

 

deal with installed software changes crashing all systems at random intervals:

 

total time of other staff in helping you with previous item:

 

fix software:

 

compile:

 

test:

 

install:

 

deal with innaccurate bug reports from 2 percent* of your userbase:
(*please round up to nearest whole human being)

 

deal with accurate bug reports from 1/2 percent* of your userbase:
(*please round up to nearest whole human being)

 

fix user's legitimate complaints:

 

compile:

 

test:

 

install:

 

document the complete redesign that you now realize the system needs, but that you don't have time to do:
