Application Development, Support and Renewal (ADSR)

The challenge

AppdevMany businesses have bespoke IT systems which have, over the years, been extended and integrated with a number of 3rd party components, often with a high level of complexity.

This leads to a significant amount of interdependency, vendor lock-in and frustration amongst those who are subsequently tasked with making changes to those systems to align them with ever-developing business strategy.

The complexity and inflexibility of these systems can lead to the consumption of considerable internal resource in order to be able to fully understand the effect of applying any change to the system. In our experience it is not uncommon in such systems that making a simple change in one functional area of the system, can introduce multiple defects elsewhere.  

This lack of understanding of both the application and its interaction with the databases typically leads to the systems becoming unstable over time.

Often, the business IT strategy is to move towards more modern, industry standard technology, but in scenarios where even comparatively simple change projects can have such severe implications in terms of business and commercial risk, any form of major transformation is often considered unfeasible, or even unthinkable.

The solution and benefits


Jumar Solutions has a proven track record in rapidly understanding these complex systems and third-party components - and then developing and executing a robust roadmap for their improvement and/or transition to more maintainable technologies. 

Its team of system renewal experts undertake development over the entire software lifecycle. Where required, the improved code can be transitioned to our ITIL-based support function (including genuine 3rd line support). The company’s heritage in transforming complex IT systems enables it to provide advice and guidance on how the system can be improved and maintained in a manner which:

  • reduces the total cost of ownership 
  • improves performance and stability of the system
  • reduces risks associated with making changes to the system
  • accelerates deployment time of any changes
  • implements software control and release management
  • increase the ability for digital enablement allowing exposure to web and mobile technology
  • allows clients to take control of their IT estate 

The approach

Jumar employs a five-stage process.  Please click the image below to see more detail:


The first stage in any engagement is for Jumar to become a subject matter expert on all areas of the bespoke system, and build up an empathy with all relevant stakeholders.

Jumar has a track record in flexible delivery management, and can take on responsibility for the running of the system, either in whole or in part. 

Its proven processes in...

  • Service take-on
  • Understanding current landscape to a very detailed degree
  • Service management
  • System rationalisation/re-architecting

…are the result of the company’s long and successful history in modernising and supporting enterprise-level IT systems or all sizes in dozens of countries worldwide.

Ongoing relationships are underpinned by Jumar’s proven ability to provide support for organisations during any transformation project – particularly where it involves a major operational and/or cultural change.
