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.<br>The latest revision of the data includes updated information for all eight projects in the form of individual spreadsheets for each project. The updates include: · All new spread sheets have the pre-fix – EDM. All original datasets remain unchanged. · Earned Duration Information has been added to each project. The ability to create an EDM baseline and record actual EDM data or progress is simplified using the spreadsheets. Tasks, start and completion dates are simply copied into the spread sheet and the data for the EDM baseline, TPD and TED s-curves is created. The spread sheets also include various mechanisms for recording or estimating work progress. · Actual start and finish dates have been added to each task for each project. The previous dataset only recorded the progress of each task at the completion of a reporting month. This update provides greater granularity for start and finish dates for each task.<br>

本数据集涵盖6个项目的项目组合，每个项目均配有基于标准化第一性原理、自下而上估算方法得出的项目管理预算（PMB）。该预算采用同质的消耗性与非消耗性资源集合，这些资源以高度复杂的多维度方式相互关联，且在资源数量、生产率与成本费率之间具备恰当的相关性。
本数据集还包含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。本次共收集并归因了12139笔实际成本，且在连续近109周的周期内开展进度测量，该标准统一的采集流程贯穿全部6个项目，为本数据集区别于其他同类数据集的独特优势。该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，或是多资源约束项目的管控研究——此类项目通常以标准化方式集体管理，以支撑战略业务目标。
本数据集的最新修订版包含针对全部8个项目的更新信息，以每个项目单独的电子表格形式呈现。更新内容如下：
· 所有新增电子表格均以“EDM”作为前缀，所有原始数据集均保持不变。
· 为每个项目添加了挣值工期信息。借助该电子表格，可简化EDM基准的创建以及实际EDM数据或进度的记录流程：只需将任务、开始与完成日期复制至电子表格，即可生成EDM基准、TPD与TED S曲线所需的数据。该电子表格还集成了多种工作进度记录与估算机制。
· 为每个项目的每项任务新增了实际开始与完成日期。此前的数据集仅会记录报告月度结束时的各项任务进度，本次更新为每项任务的开始与完成日期提供了更精细的粒度。
