minimize delays, reduce errors, and optimize resource use.
3. Input-Output Transformation – Raw materials, labor, and information are converted
into finished goods or services through structured activities.
4. interconnected – Processes consist of multiple interconnected stages. The output of
one step becomes the input for the next, requiring coordination to ensure smooth
operations and avoid bottlenecks.
5. Repeatability – A well-designed process should be consistent and reproducible,
ensuring that quality and output levels remain stable over time.
6. Measurability – Processes should have clear metrics (e.g., time, cost, quality, weight) to
evaluate performance and identify areas for improvement.
7. Flexibility – A process should be adaptable to changes in demand, technology, or
market conditions to ensure long-term sustainability.
8. Scalability – The process should be capable of handling increased volumes of input
without compromising quality or efficiency.
9. Continuous Improvement – Regular reviews and optimizations should be conducted to
