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?
• asset management policy• operational need• cost effectiveness • influence on organisation

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.
