Findings influencing factors and outcomes

ResourcesResource decisionsInfluencing factorsCostResilience
Spare parts and toolsQuantity
  • Availability and quality > price (regulations and company philosophy)

  • Collaboration with other water supply companies (regulations)

  • Variety of materials required/ used (geographical spread and network properties)

  • Different levels of inventory throughout year (network properties)

  • Hire tools (network location and geographical spread)

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)

LogisticsNAIncreased costs: larger distances (fuel consumption)Decreased velocity: spare parts and tools further away
ManpowerQuantity
  • Keep spare capacity (regulations)

  • Decentralized spare capacity throughout network (geographical spread)

  • Different amount of staff on standby throughout the year (network properties)

Reduced costs: decreased amount of staffNo change: no capacity problems
LogisticsLarge driving distances (geographical spread)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

Composition/ Localization
  • If disruption > 24-h decision rights shift from decentral to central (regulations)

  • Variety of competences needed (geographical spread)

  • Decentralized amenities

  • → Provide extrinsic motivation (geographical spread and network location)

  • → Knowledge exchange (geographical spread, network properties)

  • Decentralized decision rights (geographical spread)

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
InformationPurpose
  • Instructions: Decentralized decision making, but centralized if disruption >24 h requiring a crises team and involvement of government (regulations)

  • Reference, instruction and control

  • →Knowledge repository (geographical spread, network location and network properties)

  • → Preventive maintenance costs are high (network location)
