Value stream mapping (VSM) is a lean-management method used to analyze and design the flow of materials and information required to bring a product or service to a consumer. It offers a visual representation of a process's value-adding and non-value-adding steps, enabling organizations to identify waste, reduce delays, and improve overall efficiency. The purpose of VSM is to foster a comprehensive understanding of the entire process, from raw material acquisition to delivery, allowing targeted improvements that enhance customer value while minimizing resource expenditure (Martin & Osterling, 2014).

In executing a current state VSM, the first step involves mapping out all process steps as they occur presently. This includes documenting each activity, the responsible personnel, cycle times, wait times, and the information flow between process steps. IT systems often play a pivotal role, streamlining communication, data collection, and decision-making. For example, integrating an enterprise resource planning (ERP) system can synchronize production schedules, inventory management, and order processing, thus reflecting real-time data in the VSM (Rother & Shook, 1999). Typically, the process steps are depicted in sequence, with the process owner indicated above each step, alongside the measurement metrics, such as lead time (LT) and process time (PT).

Lead time indicates the total duration from the initiation to completion of a process, encompassing both value-added and non-value-added activities. Process time measures the actual working time spent on value-adding tasks. Accurate measurement is crucial in identifying bottlenecks or delays that hinder flow efficiency. For example, a bottleneck might manifest as a step with significantly longer lead and process times, such as manual inspection or approval processes that could be automated (Womack & Jones, 2003).

A comprehensive VSM includes assigning specific LT and PT values for each process step based on data collection, which may involve observing operations or extracting information from IT systems. The overall process efficiency is often expressed through metrics such as the activity ratio, calculated as the ratio of value-added time to the total lead time, providing insights into the proportion of time spent on value-creating activities (Liker, 2004). A high activity ratio indicates a leaner process with minimal waste, whereas a lower ratio suggests inefficiencies and potential areas for improvement.

Creating a current state VSM also involves noting any process inefficiencies or challenges. Common issues include excessive wait times, redundant activities, or inefficient communication channels. Bottlenecks are specific process steps where flow constriction occurs, leading to delays and accumulation of work-in-process inventory. For instance, a lengthy approval step or a slow IT system can cause such bottlenecks, disrupting the smooth flow of activities and increasing overall lead time. Identifying these bottlenecks is vital for developing targeted improvement strategies.

For example, in a manufacturing context, delays due to machine setups or insufficient capacity at a particular workstation can cause the entire process to slow down. In service processes, bottlenecks might occur during data processing or customer verification stages. Addressing these bottlenecks often involves process redesign, automation, or resource reallocation, aimed at balancing flow and reducing cycle times (Shook, 2009).

Overall, the current state VSM provides a snapshot of the existing process, accounting for actual data and identifying areas where waste and delays occur. It serves as a foundational tool for future improvement efforts, including designing a future state VSM that streamlines flow, reduces waste, and enhances value delivery—ultimately aligning process capabilities with customer expectations.
