Abstract

Delivery complexity is recognized universally as continually increasing; suggesting that Complexity or Difficulty Assessment Tools (CATs/DATs) are even more critical for ensuring that the right delivery approaches are selected. However, these tools appear immature, with significant diversity between the tools. Consequently, which tool to use, or type of tool to develop, becomes a critical decision. This paper seeks to identify what a good DAT looks like by extracting and discussing potential benefits from assessing a range of tools/papers and direct observation. It then assesses the three identified categories of DATs - the four-box model, the questionnaire-based approach and the top-down (TD)-based approach - for potential suitability in meeting these benefits. The TD approaches scored well, even accepting the limitation of the assessment. This paper concludes that new DATs should be developed using TD approaches, replacing the questionnaire based approaches, which are difficult to modify, and hence cannot readily keep up with the pace of change.
下一代难度和复杂性评估工具的评估方法
交付复杂性被普遍认为是不断增加的;这表明复杂性或难度评估工具(CATs/ dat)对于确保选择正确的交付方法更为关键。然而,这些工具似乎不成熟,工具之间存在显著的差异。因此,使用哪种工具,或者开发哪种类型的工具,就成了一个关键的决定。本文试图通过提取和讨论评估一系列工具/论文和直接观察的潜在好处来确定一个好的数据是什么样子的。然后,它评估了三种确定的dat类别——四箱模型、基于问卷的方法和基于自上而下(TD)的方法——以确定满足这些好处的潜在适用性。即使接受了评估的局限性,TD方法也取得了不错的成绩。本文的结论是,应该使用TD方法开发新的数据集,以取代基于问卷的方法,这些方法难以修改,因此无法及时跟上变化的步伐。
