Course: Lean Management
Topic: Analysis and Improvement of a Customer Service Process
Students work collaboratively to analyse a real process, drawing on previously developed
theoretical knowledge.
Stage 1. Process Observation (60 min)
Students work in teams of 4–6 and visit a shop to observe the customer service process at
the checkout. Each team member takes on a clearly defined observation role:
• one student identifies waste,
• another measures the duration of individual process stages,
• another analyses the working methods of the customer, cashier and supporting staff,
• another observes the workflow and relationships between activities.
Students do not interfere with the process; their task is solely to observe and record facts.
Stage 2. Analysis of the Current State and Makigami Mapping (180 min)
After the observation, teams create a map of the current process state. At this stage, they:
• organise the collected data,
• visualise the process flow,
• identify waiting points, disruptions and waste,
• compare the different perspectives of the observers.
Stage 3. Problem Analysis and Prioritisation (90 min)
Teams identify the key problems within the process and prioritise them based on:
• their impact on customer service time,
• frequency of occurrence,
• the possibility of eliminating or reducing them.
At this stage, the variability of the process and the influence of organisational and unpre-
dictable factors become particularly visible.
Stage 4. Future-State Design and Action Roadmap (120 min)
Based on the process goals and identified problems, teams design a future-state map showing
how the process could function after the proposed changes are introduced. They then create
an improvement roadmap, defining:
• proposed improvements,
• the sequence of actions,
• expected outcomes.
Students learn that designing improvements without careful observation leads to superficial
solutions rather than genuine process improvement.
