Abstract

Few studies have explored takt planning failures and how they might be better prevented. Recently Failure Modes and Effects Analysis (FMEA) has been proposed as a framework for actively preventing failure in takt planning projects. This project tests case study failures against the proposed FMEA framework as a first step to determine whether a FMEA-takt plan framework can help identify and respond to takt plan failures. In this case study, takt planning was implemented halfway through the construction of five large data centers in Utah, USA. The project was repetitive, enabling a takt of one day despite the large size of the project. Any variance from the schedule (a takt plan failure) was associated with a specific task and marked in their weekly work plans (WWPs). A reason for the variance was identified. These variances were compiled for all available WWPs and are compared to the failure categories proposed in the FMEA-takt plan framework. This study shows that the FMEA-takt plan framework is feasible with minor adjustments to account for failures in takt plans that are due to variables that are beyond the scope of a takt plan, such as unforeseen conditions or extreme weather.
