## McKinsey 7S Model
The McKinsey 7S Model analyses seven interrelated elements of an organisation to evaluate and improve organisational effectiveness. Changing one element has a ripple effect on all others.
### Hard Elements (directly controlled by management)
| Element | Description |
|---|---|
| Strategy | Blueprint to build core competency and achieve competitive advantage |
| Structure | Organisational design — degree of centralisation/decentralisation |
| Systems | Daily tasks, operations and processes to execute goals efficiently |
### Soft Elements (governed by culture; difficult to define)
| Element | Description |
|---|---|
| Shared Values | Core values reflected in organisational culture and code of ethics |
| Style | Leadership style influencing strategic decisions and people motivation |
| Staff | The talent pool of the organisation |
| Skills | Core competencies of employees that define organisational success |
> Memory Aid: Hard = 3S (Strategy, Structure, Systems) | Soft = 4S (Shared Values, Style, Staff, Skills)
### Limitations of the McKinsey 7S Model
1. Ignores the external environment — focuses only on internal elements
2. Does not clearly explain organisational effectiveness or performance
3. Considered static and less flexible for decision-making
4. Criticised for missing real gaps in conceptualisation and execution of strategy
