Agility
Agility as a competitive advantage
Agility is more than a methodology; it is a strategic competence. More and more scientific and business insights confirm the power of organizational agility as a determining factor for future success.
The agility of an organization is partly determined by:
- leadership culture
- technological flexibility
- customer focus
- innovation power
- adaptability of employees
Barnes & Sheffield supports organizations in strengthening these pillars, so that they are ready for the challenges and opportunities of tomorrow.
Global Supply Chain Agility
one coherent strategy
In international markets, the ability to switch quickly and efficiently is crucial. According to modern frameworks, Supply Chain agility is determined by flexibility in:
- product development
- purchasing
- production
- logistics
Each of these domains revolves around scope and adaptability, two factors that are directly related to the performance of the total chain and thus to global competitiveness.
Barnes & Sheffield helps organizations analyze, strengthen, and integrate these factors into one coherent strategy.

Lean & Agile
The perfect balance between stability and flexibility
© Lean frameworks & tools, Prof. Dr. Ir. Dirk Van Goubergen
Modern organizations operate in a dynamic environment where change is the only constant. Lean and Agile offer powerful, complementary frameworks.
Where Lean focuses on stability, standardization, and creating flow, Agile focuses more on agility, speed, and responsiveness. Together, they form a solid foundation for organizations that want to excel in both predictable and unpredictable market conditions.
At Barnes & Sheffield, we translate these principles into concrete improvements in your organization: clear, pragmatic, and always in line with your strategic ambitions.
What is Lean?
Lean is a business strategy to organize and improve operational activities within your company based on design principles that have proven their effectiveness in large international companies for quite some time. This method is applicable in production, office and service environments, and in the healthcare sector. Lean is not a project, nor a goal. It is a way of thinking and acting.
Why Lean?
More than ever, companies face the challenge of meeting the high expectations of their customers in today’s complex and competitive environment. Whether this concerns the quality of a product, quick advice, an urgent solution, or the diagnosis of a patient.
Benefits of Lean
Lean as a business strategy leads to shorter lead times, reduced unnecessary actions, lower costs, increased customer satisfaction, higher quality, and improved employee engagement and satisfaction. All of this results in significant competitive advantages for your organization. The emphasis is on working smarter, not harder.

When should you engage me?
Delivery, productivity, margin, quality, or planning are deteriorating.
The organization is caught up in firefighting, and management routines no longer provide control.
Forecasting, planning, purchasing, production, inventory management, and customer delivery are disconnected.
The strategy exists, but execution, accountability, and buy-in are missing.
A leadership gap in a factory, operations, supply chain, or business unit requires immediate, experienced support.

Effectiveness vs Efficiency
Difference between Operational Effectiveness and Efficiency: Let’s elaborate on this academically and from a Lean Operations Management perspective.
Most consultancy firms usually only work on Efficiency and not also on Effectiveness.
Source: Lean Green / Black Belt training, Prof. Dr. Dirk Van Goubergen, Lean Academy
- Definition: The ability to optimally use resources to generate output.
- Focus: How the result is achieved (with minimal waste).
- Lean approach: Efficiency focuses on reducing Muda (waste)
- Formula: Efficiency = Output / Input (or more operationally: actual output / potential output given input)
- Definition: The extent to which the output aligns with the intended objectives or customer value (VoC: Voice of the Customer).
- Focus: What is achieved (and whether that adds value).
- Lean approach: Effectiveness is about delivering value according to the customer definition of quality, delivery time, and specifications.
- Formula: Effectiveness = Intended Output / Realized Output (alternative: goals achieved / goals planned)
We can represent this as:
- Efficiency measures the relationship between input and output Resource utilization: Materials, Money (Euros), People (labor), Energy, Capital (CAPEX), liquid assets, Know-how (knowledge).
- Effectiveness measures the relationship between output and goals (value delivery).
Situation: A production line produces 100 units per day.
- Input: 10 operator hours.
- Intended output (customer demand): 120 units per day.
Calculations:
- Efficiency = 100 output / 10 input = 10 units per hour.
- Effectiveness = 100 realized / 120 requested = 83% goal achievement.
Interpretation:
- The line is efficient (little waste per hour), but not effective, because customer demand is not fully met.
- Lean focus: strives for simultaneously high efficiency and high Effectiveness.
-
Risks:
Efficiency only → processes run economically, but may not deliver what the customer needs (overproduction or wrong products).
Effectiveness only → correct customer value, but possibly with waste and high costs. - Goal: Flow + Value → delivering the right products / services (Effectiveness) with minimal resources (efficiency).
Organizations often ask for interim managers with experience in the industry.
