IT Service Catalogue

The LEXTA approach to developing an IT service catalogue enables our clients to flexibly create IT services from modular IT service components and thus ensure that IT optimally supports business processes. .

A wide range of best practice templates ensures that the IT service catalogue is transparent, in accordance with market standards, and benchmarkable, including in terms of service level agreements and operational level agreements. To achieve this, LEXTA consultants adapt these templates to the individual client requirements, following a pragmatic approach instead of maximizing the depth of detail.

IT Service Catalogue: Targets and Requirements

  • Usage-based IT cost allocation
  • Budgeting is noticeably simplified and conversations with service users become easier.

  • Identifying cost drivers and levers
  • The IT organization’s services, quality, quantity structure and costs / prices become truly transparent.

  • Standardization of necessary IT services
  • Individual solutions are optimized to an economically reasonable level.

  • New IT services can be introduced flexibly and quickly
  • Tested component logic and standardizations minimize the cost of extensions and changes.

  • Improved steering of IT
  • Distinct responsibilities for services are defined and a base for meaningful leadership and decisions is created based on key figures.

  • Preparing for IT benchmarking and individual right sourcing
  • We deliver a service cut in accordance with market standards as well as costs / prices per defined service on the market.


As is our usual practice, we start IT service catalogue projects with an initialization phase during which we clarify deadlines and responsibilities and agree on the detailed scope. Once project planning is complete, the further process can be divided into 4 phases:

In an as-is-assessment we first analyze the current documentation and review the existing portfolio with regards to services provided, service levels, quantity structures and their variability as well as cost and price structures. A GAP analysis shows the resulting findings.

Using best practice approaches we then devise a service model and develop a technical service catalogue. This work leads to a business service catalogue with measured quantity structures adapted to your requirements and needs.

In the subsequent finance phase we draft a financial model displayed in spreadsheets and carry out unit cost calculations for services. This detailed assessment guarantees complete cost transparency of the services.

Finally, we plan the changes during transition to ongoing operations and document aspects such as elements and roles for the service model. We conclude the project with a final implementation plan and documentation.

Services of the IT Service Catalogue

The IT service catalogue largely covers the range of IT services – best practice profiles are available for all typical services:

  • Standard IT services (such as client PCs, e-Mail)
  • Network services
  • Computer center services
  • Standard applications (SAP)
  • Individual applications

Cost and performance accounting

Within the service catalogue project, we use cost object accounting to determine the actual costs of the defined IT services without overlap.

Cost type accounting Cost center accounting Cost object accounting
Which costs occur? Where do costs occur? What do costs occur for?
Cost type accounting forms the starting point and base of the entire cost accounting. Typical cost types within the scope of review are:
  • Personnel costs
  • External service providers
  • Depreciation of hard- and software
  • Hardware maintenance
  • Software support
  • Consumables
Cost types are then collected and assigned to independent fields of responsibility. Cost centers can be created based on following criteria:
  • Functional (e. g. IT purchasing)
  • Personnel (e. g. department server operation)
  • Local (e. g. computer center)
  • Calculatory (e. g. Oracle licenses)
Finally, costs are collected again and allocated to IT services (cost objects). This provides the base for unit cost accounting and Pricing.
