Job description
The Capacity Management team (part of the Service Strategy and Operations department within the Group Technology Services Division) is currently organized around 3 main domains: One domain is responsible for the Mainframe and Tandem technologies, another domain is specialized in the Distributed Technologies and the third domain is supporting Business and Service Capacity Management. The team is responsible for a full set of activities covering both Capacity and Performance aspects. It produces the “capacity plan” on a yearly basis and performs monthly follow ups; it collects the demand and forecasts the need in term of IT infrastructure; it handles capacity and performance operations to prevent Capacity and/or Performance incidents. All of this is done keeping in mind the cost impact (hardware and software) of IT infrastructure evolution.
The team is also involved in various projects, ensuring that an application is rightly sized and well-tuned before going in production. Via the projects, capacity indicators are selected to report on resource usage, quality of services and Business volume evolution. Based on this, the team develops models to correlate resource consumption with volume changes and quality of service.
Finally, the team took over the Volume forecast activity, aiming to forecast the cost of IT services to be recharged to our customers. This activity is based on actual and forecasted resource consumption of the IT services, often in line with Business evolution. The forecast is monitored on a monthly basis to identify any deviation and adapt the associated cost for the customer.
