If Cpm Is so Bad, Why Have We Been Using It so Long?
Why has the Critical Path Method (CPM) been used so widely for so long given its inability to produce predictable outcomes? For shedding light on this paradox, the formative period of the CPM is analysed from two main angles. First, how was the CPM embedded into the construction management practice? Second, what was the methodological underpinning of the development of the CPM? These questions ...
متن کاملClinical terminology: why is it so hard?
Despite years of work, no re-usable clinical terminology has yet been demonstrated in widespread use. This paper puts forward ten reasons why developing such terminologies is hard. All stem from underestimating the change entailed in using terminology in software for 'patient centred' systems rather than for its traditional functions of statistical and financial reporting. Firstly, the increase...

Given that parallel systems are now well within the budget of the typical hobbyist or graduate student, it is not unreasonable to expect a new cohort in excess of several thousand parallel languages and environments to appear in the 2010s. If this expected new cohort is to have more pra...
متن کاملRecruitment to trials - why is it hard and how might we make it less so?
Background Recruiting participants to trials can be extremely difficult. Estimates of just how difficult vary but around half of trials fail to recruit their original target sample size. Poor recruitment can lead to an underpowered study, which may report clinically relevant effects to be statistically non-significant. A non-significant finding increases the risk that an effective intervention ...
متن کاملWhat Is Software Testing ? And Why Is It So Hard ?

Because of time constraints, it’s not uncommon for developers to release untested code—code in which users can stumble across bugs. ■ The order in which statements were executed in actual use differed from that during testing. This order can determine whether software works or fails. ■ The user applied a combination of untested input values. The possible input...
