Common Challenges

  1. Complex Landscape

    Often the full application portfolio is unknown, with information residing in a complex landscape of systems, people and artifacts.

  2. Unwieldy Portfolio

    Even if the portfolio is known, ongoing management is laborious and error prone, relying on the maintenance of Excel and other MS Office documents. Collaboration and communication is rendered extremely difficult.

  3. Time Consuming and Costly Assessment

    Gathering vital data from application owners to understand how rationalization impacts and informs decision making is vital, but often tedious and reliant on expensive consultancy to conduct interviews and assessments.

  4. Buried Information

    Key information pertinent to the rationalization effort may be stored in disparate systems, such as CMDBs, making it difficult to collate

  5. Uncertain Methodology

    Organizations attempt to devise methodologies for assessing or scrutinizing the portfolio, or for structuring application portfolio data without knowledge of industry best practices or methods. Often, this results in a directionless or drawn out project.

  6. Lack of Visibility

    Teams undertaking rationalization often lack the tools and techniques required to efficiently and effectively visualize application data.

Application Rationalization in Four Weeks


Kicking off an application rationalization project will require input, such as:


  • The application catalog (whole or in fragments).
  • Artifacts linking application to business capabilities, technologies, and related concepts.
  • Lists of application owners, vendors, locations and meta-data.
  • Scoring questionnaires and worksheets.

Week One

Establish Goals and Centralize Data

  • Establish your goals and parameters for this application rationalization initiative e.g. functional duplication; vendor consolidation.
  • Gather and load available application data into the iServer repository, centralizing the disparate data sources. Predefined data fields structure and guide data towards best-practice analysis.

Week Two

Assess and Augment Data

  • Start to build a comprehensive picture of impacts by easily linking applications to key enterprise concepts, such as business capabilities, all from within the iServer repository.
  • Use predefined scoring methods to survey application owners or other SMEs throughout the business, filling in gaps and gathering key information on applications.
  • Collate all information seamlessly and dynamically in the iServer repository.

Week Three

Visualize and Analyze Your Application Portfolio

  • Bring your application portfolio to life through powerful predefined visualizations and reports.
  • Quickly and clearly visualize your portfolio according to the key criteria identified at the start of the initiative, and use industry best-practice methods, such as TIME analysis.

    iServer has met our requirements and expectations. Orbus have provided attentive and timely support throughout our relationship.
