PurposeThis paper offers a measure of sensitivity to change orders in the later stage of the construction phase to characterize the distribution of project activities around the time when the project is scheduled to finish.Design/methodology/approachThis paper employs eigenvector centrality to identify the sensitivity of an activity to change orders based on the sensitivity of its neighboring activities. Next, a distance-based measure, called the radius of gyration, is adopted to describe the distribution of project activities around the time when the project is scheduled to finish. Finally, a sensitivity measure, which quantifies the dispersion of project activities from the project finish date, is developed.FindingsTwo real-life construction projects are used to measure the sensitivity to late changes. The results conform to the intuition of sensitivity to late changes and confirm that the negative effects of change orders are amplified when project activities are scheduled to start closer to the finish date.Originality/valueThis paper adds to the literature on change orders in construction projects by developing the first method for quantifying the sensitivity of projects to the issuance of late changes. The proposed method can provide valuable information to project owners and construction managers as they negotiate the pricing of change orders based on their time of occurrence.

In today’s manufacturing industry, companies operate in a complex and rapidly changing environment, resulting in an increasing number and variety of Manufacturing Changes (MCs). To ensure long-term competitiveness, companies must respond quickly, flexibly, and effectively to various types of MCs. While many companies have established processes to manage MCs, these processes often lack flexibility and a comprehensive methodological and digital support. Existing approaches to support these processes are often generic and difficult to transfer to a company’s unique Manufacturing Change Management (MCM) process. For this purpose, a framework and an associated application method have been developed in which MCM processes are abstracted and mathematically modeled using descriptive and characterizing attributes. To achieve a comprehensive view of the processes, the holistic framework intends to model people’s activities involved in the process, process steps, and the occurrence of information inside the process. The framework was developed through a three-phase approach, with attributes derived from the literature, case studies, and expert interviews. The framework and the associated application method were tested in a first industrial use case. In conclusion, the framework developed in this contribution supports practitioners and researchers to consistently describe and to flexibly adapt generally valid theoretical and practical approaches to company-individual MCM processes.
