The End2End Capacity Planning Project
The experienced service problems demonstrated some weak points in the Capacity Management Process :
The capacity planning was an activity distributed over the different infrastructure departments
The capacity planning process was not always formalizedBasic performance data not always available or put in a
Performance DBApplication drivers not always used or availableNo End2End view on the available/needed capacity for the
applicationPlanning mostly made based upon simple extrapolationProcess with very uneven maturity level
SAS FORUM 22/6/05 - J.P. Remory
The End2End Capacity Planning Project
A project leader has been appointed A theoretical model has been developedThe platforms in the scope for the capacity planning project
were identifiedThe technical solution has been setupAnd as usual, a planning has been proposed

Main objective of Capacity Management : To Manage our actual and future ICT-Configuration as
efficient as possible, respecting the SLA
Capacity Management activity can be seen from different points of view :
Functional : Capacity management is a set of functions concerned with determining and maintaining
the proper balance between workloads and resourcesproviding high service levels for the supported applicationat minimum cost
Departmental : Capacity Management needs a x-platform approach and should be implemented for both mainframe and distributed systems. Every concerned department should be implicated in the process. Organisational : Capacity Management activity builds, operates and maintains an organisation to meet the capacity management objectives.
Capacity Planning : a Capacity Management Process
SAS FORUM 22/6/05 - J.P. Remory
In the Capacity Management Model used in Fortis, different activities are related to each other to realise the SLAs, Capacity Planning (Workload Management) is one of them. SLAs are considered as the driving force that enforces these activities
