Definition
Scalability is the property of a system to handle a growing amount of work by adding resources, or its potential to be enlarged to accommodate that growth.
Why It Matters
Scalability is the difference between a successful prototype and a world-changing system; without it, a system becomes a victim of its own success, collapsing under the weight of the growth it was designed to achieve.
Core Concepts
- Throughput: The amount of work a system can perform in a given time.
- Efficiency at Scale: A truly scalable system maintains its efficiency (or even increases it) as it grows.
- Bottlenecks: Components that limit the overall growth of the system.
- Standardization: SOPs are the “code” that allows human systems to scale without chaos.
