|Abstract: ||Many companies have had adverse experiences of information system costing more and delivering less
than originally planned. This thesis proposes a tool set for effective IT portfolio management. RollsRoyce
Naval Marine sponsored a study to create, develop and evaluate a practical IT portfolio
management toolset. One implication of this was tat the study took place entirely within a 'live'
environment - the tools were developed in close partnership with the employees of Rolls-Royce, and
the work performed was a significant contributor to the profit margin of Rolls-Royce Naval Marine
Support. The initial version of the toolset was piloted in the Configuration Management area of the
Submarine Support business units. Other Rolls-Royce business units then provided a test for the
general applicability of the methodologies and tools developed. The objectives of the IT portfolio
management strategy were to maintain current business capability, enable future business, and where
possible, identify possible cost savings through betrer usage of information.
The portfolio management framework drew upon Checkland's soft systems methodology, extensively
adapting it to suit the specific situation faced. Various tools were employed to solicit current and future
business requirements. Feature analysis was evaluated for use in matching features to systems, cost,
strategic intent, and process. Diagrammatic tools included different types of rich pictures, entity
relationship diagrams and contextual data flow diagrams. Gap analysis illustrated the difference
between capability and requirements. Techniques were developed to portray the results so that they
could be effectively communicated. Options were evaluated using various methods for assessing costeffectiveness.
A technique was developed to manage the various stakeholders involved in the
information systems strategy.
The output was a cost-effective, implementable strategy that supported both current and future business
requirements, and had buy-in from users, developers, and management. The IT portfolio management
strategy was evaluated by identifying actual and potential operational savings, leading to a
rationalisation of the methodology to provide more flexibility.
The IT portfolio management strategy developed is specific to the business site. However, the process
by which it was created can be used by any business, and is very flexible. Several of the tools have
been used in other parts of Rolls-Royce with success, two of them are under consideration for adoption
into Rolls-Royce processes for global deployment. IT portfolio management in other areas of RollsRoyce
is being increasingly influenced by the framework and toolset created during this thesis.|
