Process Walk Interview Sheet

Continuous Improvement, Gemba, Lean Manufacturing, Process Improvement, Process Mapping, Process Optimization, Quality Control, Quality Management, Value Stream Mapping

Objective:

To systematically gather information and observations about a process directly from the people involved by walking through the process steps.

How it’s used:

A structured form or checklist used during a Gemba walk (going to where the work is done) to guide questions, record answers, observations, and identify potential issues or improvement opportunities related to process steps, inputs, outputs, and controls.

Pros

Provides firsthand understanding of the actual process; Facilitates engagement with front-line employees; Helps identify hidden inefficiencies and problems; Gathers qualitative data that complements quantitative analysis.

Cons

Can be time-consuming; Information gathered can be subjective or anecdotal if not structured well; Requires good interviewing and observation skills; Potential for observer bias.

Categories:

Human Resources, Lean Sigma, Manufacturing, Problem Solving, Quality

Best for:

Gaining deep insights into the current state of a process and identifying improvement opportunities through direct observation and interaction with those performing the work.

The Process Walk Interview Sheet methodology is particularly effective in industries such as manufacturing, healthcare, and software development, where complex workflows necessitate a thorough understanding of day-to-day operations. This approach is typically employed during improvement initiatives or quality management projects, allowing teams to capture real-time information directly from the work environment. It is often initiated by process improvement teams, quality assurance personnel, or project managers, who engage with frontline employees—those who are intimately familiar with the processes—thereby fostering collaboration and transparency. In the healthcare sector, for example, this methodology can uncover inefficiencies in patient flow or medication administration by allowing observers to see the process in action and grasp the challenges faced by healthcare staff. Similarly, in manufacturing, it can reveal bottlenecks in production lines, leading to enhanced operational efficiency. The sheet not only prompts systematic inquiry into inputs and outputs but also encourages participants to voice concerns and suggestions, which enrich the qualitative data gathered. This data complements traditional metrics, such as cycle times and defect rates, and can be instrumental during phases such as Lean Six Sigma projects aimed at reducing waste and improving customer satisfaction. Participants of the Process Walk Interview Sheet are encouraged to formulate inquiry questions that touch on various aspects, such as safety regulations or compliance with procedures, ensuring a comprehensive evaluation of each process step.

Key steps of this methodology

Visit the work location and observe the process in real-time.
Engage with employees to understand their tasks and challenges.
Ask open-ended questions to clarify specific process steps.
Document observations and interactions directly on the interview sheet.
Identify variations from standard procedures during the walkthrough.
Look for signs of waste or delays in the workflow.
Discuss inputs and outputs of each step with the team members.
Inquire about existing controls and metrics used to assess performance.
Record any additional comments or insights from employees.
Conclude the walk with a discussion on potential areas for improvement.

Pro Tips

Incorporate visual aids such as process flow diagrams during the interview to facilitate clear discussions and immediate identification of bottlenecks.
Utilize the "5 Whys" technique to delve deeper into specific issues identified; this reveals root causes that may not be evident at first glance.
Regularly update your Process Walk Interview Sheet based on prior experiences; include lessons learned and adapt questions to focus on newly identified challenges.
