Research• How can operational need be determined so that

a long term asset management policy for a civil infrastructural work can be developed with the aim of achieving cost effectiveness during its life cycle?

Operational need

Operational need

• Operational need is a statement of required capability, reliability and availability.

Operational need• formulation of the problem• formulation of a concept policy• evaluation of the concept policy from the point of

view from the stakeholders• iteration• repeat evaluation

Influence of operational needOrganization Sober performance High performance

Size (no. of

employees)

Decreases, expected is that in this

scenario intervals of certain tasks will be

larger. This will put a smaller strain on

the organization (less tasks per shift).

The organization can do with less

employees.

Decreases, the organization will be

smaller, because a high level of skills is

necessary for tasks. Outsourcing is

therefore unavoidable

No. of tasks Decreases, because of the lower

ambitions, certain tasks (cleaning,

replacement of lamps, non mandatory

checks) will have a lower frequency.

Equal, the number of tasks is expected

to be equally. Improvement in scheduling

of tasks (clustering), in efficiency of

tasks (for example by better tools and

methods) is necessary to increase

performance (more reliability and

availability)

Education Equal, although the number of tasks

decreases due to larger intervals, the

type of tasks will be the same.

Employees with the same type of skills

(mostly technical) will be necessary.

Shift in education, there will be a shift

from technical orientated employees to

management orientated employees,

because outsourcing and better

scheduling demands good management

skills.

Conclusion & recommendations• Literature

• what is expected from the policy executing organisation;

• the ability of the organisation to execute the policy;

• willingness of the organisation to execute the policy.
