Consultants must be able to act decisively and thoughtfully under pressure, ensuring all client needs are met, even when handling multiple projects simultaneously.

Expertise interviews may include coding tests, product discussions with our product engineers, or coaching and agile methodology threads with our Product Owner and Scrum Master.

You should ask well-thought questions informed by prior research, presented in a structured manner, and supported by poise follow-up questions. Example: 'I talked to [consultant] who said consulting requires substance and people skills. In this office, how much does each contribute? And which skill can I focus on beforehand?'

- JIT is a strategy used to generate items at the exact time they are needed in the production process, minimizing inventory and storage costs. Just-in-Time (JIT) in Lean is a production strategy that aims to produce items at the exact time they are needed in the production process. The objective is to reduce stock levels and associated carrying costs while ensuring that products are manufactured efficiently to meet customer demand. - JIT emphasizes a pull system, where production is triggered by actual customer orders, reducing the risk of overproduction and associated waste. It also involves close coordination with suppliers to ensure timely delivery of materials, contributing to overall efficiency and responsiveness in the production system.

At a chemical processing facility, I identified a compliance gap during routine operations, where hazardous materials were not properly documented or stored according to OSHA regulations. I immediately coordinated with management and compliance officers to rectify the documentation issues, implemented rigorous training sessions, and introduced clear visual management indicators for storage areas. Within months, our subsequent audits demonstrated full compliance, significantly reducing safety incidents and enhancing regulatory confidence.

Lean seeks to eliminate overburden by optimizing work processes, ensuring realistic workloads, and preventing employee burnout through continuous improvement. Lean addresses the concept of “overburden” on employees by striving to achieve a balance between workload and capacity. This involves eliminating waste and optimizing processes to Make sure staff members are well-rested with necessary tasks. Lean principles emphasize the importance of respecting and involving employees in problem-solving, encouraging their input to improve efficiency and eliminate activities that do not add value. By maintaining a focus on continuous improvement, Lean seeks to establish a climate at work where workers feel empowered. Additionally, their workloads are aligned with their capabilities, preventing overburdening and fostering a sustainable and productive workplace.

There are many important attributes for a successful Lean Culture, but I believe that the most important one is continuous improvement. A Lean Culture is built on the principle of continuous improvement, which means that every process and every activity should be constantly evaluated and improved. This requires a lot of commitment from everyone involved, as well as a willingness to learn from mistakes. Without continuous improvement, a Lean Culture will eventually stagnate and become less effective.

Lean Six Sigma integrates Lean's focus on waste reduction with Six Sigma's emphasis on process variation reduction, providing a comprehensive approach to continuous improvement.

Measure of variation in data.

I was advising a mid-sized manufacturing company on whether to move production to Southeast Asia. The CEO had been internally advocating for this move and had already started preliminary planning. When I dug into the analysis—looking at total cost of ownership, not just labor costs—the picture was more complicated. Yes, labor was cheaper, but supply chain complexity, quality risks, time to delivery, and transition costs meant that their true cost per unit would only improve by about 8-10% over five years, and that was under optimistic assumptions. For their competitive position, it wasn't a strategic differentiator. I had to present a recommendation to stay put and instead invest in automation and process efficiency at their existing facility. I knew this wasn't what they wanted to hear. How I delivered it mattered. I started by acknowledging their concern—they were under margin pressure and needed to act. I walked through the complete financial analysis so they could see my reasoning, not just my conclusion. I also presented it as a trade-off: quick cost reduction vs. sustainable competitive advantage. And I brought scenarios showing under what conditions the offshore move would make sense. They initially pushed back, but they trusted the analysis. They ended up investing $4 million in automation, which actually yielded better results than the offshore move would have. Six months later, the CEO told me that the recommendation wasn't what they wanted to hear, but it was exactly what they needed.

Any activity that does not add value.

In a rapidly changing market environment, I once encountered a sudden drop in product demand that necessitated a swift pivot in our lean strategy. Our traditional production schedules and inventory management systems were optimized for high-volume output, but market signals indicated an imminent need to scale back. I initiated an in-depth review of our existing processes and production priorities, reallocating resources to focus on high-demand product lines while implementing more flexible production techniques, such as batch processing and modular work cells. Additionally, we revised our inventory strategy to better align with fluctuating demand. This agile adjustment minimized waste and ensured we could quickly ramp up production if market conditions improved. The pivot underscored the importance of being adaptable and maintaining real-time market insights to guide lean transformations.

Gemba is a Japanese term that means "the real place." In Lean, a Gemba walk is a structured observation of a process or work area. It involves physically going to the place where work is performed to see firsthand how things are done, identify waste, and talk to employees involved in the process. Gemba walks are crucial for understanding the actual process and identifying areas for improvement.

The three main steps in root cause analysis are as follows: First, identify the problem. Second, analyse the data to find the root cause. Third, implement solutions to prevent the problem from happening again. This approach ensures that we address the real cause of the problems, not just the symptoms.

There are a few challenges that come to mind when thinking about the role of Lean Consultants: 1. Ensuring that the client understands the value of Lean and is committed to implementing it 2. Helping the client to overcome any resistance to change 3. Ensuring that the client has the necessary resources in place to implement Lean successfully 4. Helping the client to sustain the improvements made through Lean over the long term

Using data rather than assumptions.

The most important tip is: Be yourself. Show that you're an interesting person and that you demonstrate consulting attributes (achieving/leadership/problem-solving) in everything you do.
