Project Portfolio Dataset

This dataset comprises a portfolio of six projects each having a PMB consisting of a budget derived from a standardised first-principles, bottom-up estimation technique utilising a homogeneous set of resources, both consumable and non-consumable, which are inter-related in a highly complex, multi-dimensional manner with appropriate correlation between quantity, productivity rates and cost rates. The data set also includes detailed time-phased actual costs and progress over the life of each project as well as the time-phased values of revenue claimed for each project. The collection and attribution of 12,139 actual costs and the measurement of progress over a period of just under 109 consecutive weeks is consistent and standardised across all six projects providing a unique differentiator to other datasets. The data was collected over a continuous 109 week period, and is valid for research in portfolio, program or project management or control of multiple resource-constrained projects, where projects are managed collectively, generally in a standardised manner to support a strategic business aim.

本数据集涵盖由六个项目构成的项目组合，每个项目均配备项目管理基准（PMB），其预算基于标准化的第一性原理自下而上估算方法生成。该方法采用一组同质的消耗性与非消耗性资源，这些资源以高度复杂的多维方式相互关联，且在资源数量、生产率与成本率之间存在合理的相关性。本数据集还收录了各项目全生命周期内的详细分时段实际成本与进度数据，以及各项目申报收入的分时段价值。本次采集的12139笔实际成本的归集与归因，以及连续近109周内的进度衡量标准，在六个项目间保持统一且标准化，这为本数据集提供了区别于其他同类数据集的独特差异化优势。本数据集的采集周期为连续109周，可用于项目组合、项目集或项目管理研究，以及多资源约束型项目的管控研究——此类项目通常以标准化方式集中管理，以支撑战略业务目标。
