Pavel Azaletskiy

VSOptima

Dynamic value stream mapping (VSM)

Pavel Azaletskiy is the founder and CEO of VSOptima, a software company through which he has developed a digital twin platform to help organizations achieve operational excellence. His career to date includes stints at Google, AstraZeneca and Yandex; now as well as running VSOptima he leads the non-profit Silicon Valley Design Thinking Club at Stanford University, and is the founder of the LISA – LEAD Incubator and Startup Accelerator to help entrepreneurs make positive changes in the world.

He advocates for the use of value stream mapping and has written a number of papers on how the visual tool can help productivity, alongside its other benefits.

We caught up with Azaletskiy to ask him what potential challenges companies face when adopting value stream mapping, and he said one common misconception organizations should be aware of is that it provides a static representation of the value stream.

“It is crucial to recognize that a value stream is dynamic, and its mapping captures a snapshot of its characteristics at a given time,” he remarked. “Additionally, it is important to understand that lead time is influenced by the inflow and constraints within the value stream.”

He has led more than 500 Kaizen events in 16 countries. We recommend checking out his blog, where he muses, among many other things, on the advice Socrates would have given if he had been a Lean consultant.

Baker shared with us the best professional advice he has ever received: “Never stop learning and seeking improvement. Continuous learning and growth are essential for personal and professional development. Embracing a growth mindset and being open to new ideas, feedback and experiences allows us to continually improve our skills and capabilities.

Business resilience

Dave Crysler is the principal consultant of The Crysler Club, where he draws from his experience working in manufacturing and distribution to advise businesses on ways to cut waste and achieve operational excellence.

“I believe the most common challenge for organizations trying to achieve operational excellence is effectively communicating the vision,” Crysler told us. “I recommend taking the approach of starting with and communicating the ‘Why’ as well as the ‘What’ behind the vision before jumping into the ‘How’. Why are we wanting to make this change. What impact are we expecting to have. If these two things are communicated clearly and consistently, people are much more receptive and often contribute meaningfully to how the vision can ultimately be achieved."

They see it as a collection of activities that vary widely from day to day... When we understand leadership as processes, we begin to understand leadership in a new way, one that is critically important for doing business in the digital age: time, information, and information flow.”

Quality and improvement

Dr Rham El Sokary is lead instructor and consultant at the American University in Cairo, where since 2008 she has been teaching people the concepts of Total Quality Management, Lean Six Sigma and continuous improvement.

Her scientific background and expertise in quality and environmental health and safety mean she is in demand as a coach and project leader – in 2022, she was asked to design a program to mentor female engineers as part of a partnership led by Siemens Energy and the Egyptian German Technical Academy to help deliver Egypt’s 2030 vision. 

Explaining what “total quality” is, she recently wrote that “total quality culture is the foundation for the rise of societies and countries. We should target all types of organizations that make any type of output including services, goods, projects and software programs that are produced and delivered through governmental or private sectors, all are targeted without exception.”

“If a company wants to start transforming their corporate innovation, the first step is to identify those intrapreneurs, the builders that reside within their walls. They can start with top management.”
