Legacy Application Support

Securing the future of your established systems and software

Inevitably as with most things technology moves on with new tools, development platforms and software development frameworks ever emerging.  Yet, for most businesses the vast bulk of their IT systems and applications are based on earlier technology – legacy software and architecture.  These legacy systems often sustain the business’ IT and are core to one or more business services and its critical these established systems are supported. 

Established Systems (Legacy Software) Challenge

It’s common that IT departments follow their business drivers, investing in and acquiring new skills and experiences to secure the apps, services and mould the IT architecture towards the future IT platforms.  The IT expertise evolves and retaining the skills and experiences to sustain the Established Systems based on legacy software becomes an increasingly significant challenge. Whilst the IT architecture, software and deployment methods may be outdated, reflecting being of a past legacy, these Established Systems and their applications continue to provide services valued by their business communities, often managing data and information flows underpinning new frontline application services and systems.  These Established Systems retain business value, yet within the IT departments a skillset gap expands.

Established Systems Support

OCS Insurance has a proven track record in securing Established Systems.  Being an IT service provider for more than 30 years, OCS has provided business as usual (BAU) to many systems and applications over the last three decades.

Adopting Established Systems and Applications as their legacy nature has made them undesirables; unsupportable within their business’ IT departments, is a service OCS has and continues to provide.  The most common catalyst is the legacy systems being orphaned by new IT architectures and new enterprise platforms, such as occurs with business mergers and acquisitions.

An example of the technologies OCS is sustaining within Established Systems and Applications are:

  • Java, SEAM, Swing, Struts, Ruby, PowerBuilder, Progress 4GL, PHP, RPG, VB6, VBA, VB.NET, ASP.NET, UNIFACE, Delphi, Informix 4GL, Access, SQL Server 2000, Sybase and Oracle.

What to do with Established Legacy Systems?

What is given, is these Established Systems must work. They are delivery business services, adding value, meeting business needs. The technology may be legacy, the business services may be maturing, the skills and experiences required to sustain may become less available, there may be a timetable for decommissioning, yet today they need to work.  So a support capacity is required:

  • Internal IT – struggle to retain resources due to limited future value in the legacy skillsets, become dependent on freelancers that need to be managed and seek “commitment” that may not match to what is required (unproductive for much of the time)
  • External IT – needs to be based on a Service rather than Capacity, where “ownership” can be shared or even transferred.  Need to have capability to ensure value is sustained within the Established Systems and Applications and the business can continue to derive value from integration with new systems and platforms as and when desired.

Over three decades of custom application development and support provides OCS Insurance with a pedigree ideally suited to the legacy technologies, frameworks and methodologies abundant within the Established Systems and Applications.  High OCS employee retention within the consultant pool secures technical specialists who are proficient with current technologies and methods, yet retaining knowledge and skills of past technologies and implementation variations.  Further, OCS seeks out multi-talented hybrids when recruiting, who bring further technical depth and capability.  Our consultants are the kernel of our Established Systems and Application Support Services. 

If you’re thinking about how to maintain and support your legacy software within your Established Systems and Applications, we welcome the opportunity to assist you and secure continuing value from your Established Systems and Applications.
