I agree that time estimates are a necessary evil, but I disagree that story points are useful for anything really. This comment from the article was interesting and it matched my experience: > The law of large numbers only applies if a) the population is sufficiently large, otherwise outliers will dominate b) the estimates are at least mostly independent, otherwise systematic bias will skew the result and c) the estimate is in fact the expected value (mean average) of the probability distribution of time taken. If the estimate is a mode of the probability distribution, then you can not meaningfully add the estimate directly and be able to meaninfully say anything about the resulting distribution.
