Findings influencing factors and outcomes
| Resources | Resource decisions | Influencing factors | Cost | Resilience |
|---|---|---|---|---|
| Spare parts and tools | Quantity |
| Reduced costs of spare parts: inventory pooling |
|
| Logistics | NA | Increased costs: larger distances (fuel consumption) | Decreased velocity: spare parts and tools further away | |
| Manpower | Quantity |
| Reduced costs: decreased amount of staff | No change: no capacity problems |
| Logistics | Large driving distances (geographical spread) | Increased costs: more driving (fuel consumption) |
| |
| Composition/ Localization |
| Reduced costs: hiring of new, less experienced staff |
| |
| Reduced motivation due to changes in the localization | ||||
| Information | Purpose |
| No change | No change |
| Availability | Centralized: knowledge repository (geographical spread and network properties) | No change | No change | |
| Resource decisions | Influencing factors | Cost | Resilience | |
|---|---|---|---|---|
Availability and quality > price Collaboration with other water supply companies Variety of materials required/ used Different levels of inventory throughout year Hire tools | Reduced costs of spare parts: inventory pooling | Increased visibility and redundancy of spare parts: better overview of the overall availability of stock in one warehouse rather than three Decreased visibility and redundancy of tools: availability declined as there are less opportunities for return (see also logistics) | ||
| NA | Increased costs: larger distances (fuel consumption) | Decreased velocity: spare parts and tools further away | ||
Keep spare capacity Decentralized spare capacity throughout network Different amount of staff on standby throughout the year | Reduced costs: decreased amount of staff | No change: no capacity problems | ||
| Large driving distances | Increased costs: more driving (fuel consumption) | Increased redundancy: start work from home Decreased redundancy: more driving No change in velocity: Average response time between a disruption registered by the call center and fitters reaching leakage = 1 h | ||
If disruption > 24-h decision rights shift from decentral to central Variety of competences needed Decentralized amenities → Provide extrinsic motivation → Knowledge exchange Decentralized decision rights | Reduced costs: hiring of new, less experienced staff | Decreased flexibility: not all fitters can do every job as new staff do not have all competencies yet Increased flexibility: scheduling in one team including rotations over the geographical spread (competency development) Increased collaboration: more tacit knowledge due to one planning domain and team Reduced collaboration: less opportunities to exchange knowledge | ||
| Reduced motivation due to changes in the localization | ||||
| Information | Instructions: Decentralized decision making, but centralized if disruption >24 h requiring a crises team and involvement of government Reference, instruction and control →Knowledge repository | No change | No change | |
| Centralized: knowledge repository | No change | No change | ||
