Reducing the complexity of your apps saves you money

We help you to continuously evaluate and execute your core technology’s codebase, infrastructure and data model based on your business needs. This ensures efficiency and readiness for whatever the market brings.

We assess your application inventory to determine your strategy, providing clarity around the bigger picture for business cases and justifications.

TTG application rationalisation methodology will help you to manage your apps:

  • Discovery – we find apps and document how they are used
  • Create cohorts – we group your applications by value and complexity
  • Roadmap – we create a modernisation and migration journey for your apps
  • Execute and deliver – we manage the delivery of the roadmap

We have saved organisations £millions by helping them to focus on the right things.
