Software Application Support

Dunstan Thomas has provided outsourcing services for software support and maintenance since 1986. With ever decreasing IT budgets and legacy technology becoming harder to support internally, outsourcing has become the cost effective method of supporting internal applications. From its support base in Portsmouth, it uses remote connections to its customers’ sites to support a range of applications across a wide choice of software development platforms. Dunstan Thomas offers a comprehensive support infrastructure which can be tailored to each customer’s requirements ensuring that development teams replicate their environment as closely as possible.

Despite the risk that will arise over time, many businesses have justification for keeping a legacy software system, such as:

  • Cost and ROI – re-writing a system in newer technology is not cheapedl
  • “If it ain’t broke – don’t fix it” – the software is doing the job and replacement cannot be justified
  • Stability – the software has become stable and works well
