Modernising Legacy Systems with Project-Based Resourcing

 

Some systems in every business quietly run day after day… until one day they don’t.

 As Grace Hopper famously warned,

“The most dangerous phrase in the language is, ‘We’ve always done it this way.’”

For one Fortune 500 multinational, a set of applications more than 15 years old had quietly become a critical bottleneck. Years of incremental changes, unresolved issues, and gaps in documentation meant modernisation was no longer optional — it was urgent.

Internal teams were stretched. Specialist skills were scarce. The usual options — consultancy, outsourcing, or hiring permanent staff — each carried risks or delays that the organisation could ill afford.

This is where TechHeads’ Project-Based Resourcing (PBR) came in. It allowed the client to retain control, preserve intellectual property, and keep critical knowledge in-house, while accessing a fully dedicated, specialist development team.

PBR isn’t just another outsourcing model. It’s about embedding dedicated, self-contained teams into your project, tailored to your needs and working under your direction.

It gives organisations the flexibility to scale the team as required, without losing control or intellectual property. It also provides immediate access to specialist skills that might be difficult—or even impossible —to hire permanently.

In short, it combines the focus and accountability of an in-house team with the expertise and flexibility of an external resource.

This client’s situation was familiar to many enterprises managing older systems:

• Ageing legacy applications – The software had accumulated technical debt over 15 years, undergone numerous incremental changes, and lacked comprehensive documentation.
• Skills gaps – Very few internal engineers had experience with both the legacy technology and the modern frameworks needed for the upgrade.
• Capacity constraints – Teams were already committed to day-to-day operations, leaving little bandwidth for major modernisation work.

They needed a solution that could deliver results quickly, while keeping knowledge and control firmly within the organisation.

TechHeads initially deployed a 10-person specialist team aligned with the client’s technology stack. The team included full-stack engineers, SDETs, Angular specialists, a software development lead, and a cybersecurity expert.

Working closely with internal stakeholders, the team:

• Modernised legacy applications to meet current security and performance standards
• Created complete documentation and transferred knowledge to the internal teams
• Delivered the project on time and within budget
• Provided a sustainable, maintainable platform for future needs

The team’s structure and embedded approach allowed the client to maintain control over priorities while accessing the skills they needed immediately.

The engagement delivered outcomes that went beyond expectations:

• Ahead of schedule and under budget
• Zero risk to intellectual property — all work owned by the client
• Full knowledge retention through documentation and training
• Positive feedback from end-users on performance, usability, and stability

Beyond the numbers, the key takeaway was that PBR enabled the organisation to continue running smoothly while modernising critical systems — something traditional hiring or consultancy models would have struggled to achieve so efficiently.

Legacy systems don’t just age — they quietly slow innovation, increase risk, and make change more difficult than it needs to be. For organisations facing these challenges, hiring permanent staff or engaging traditional consultancies can be slow, expensive, and risky.

Project-Based Resourcing offers an alternative. It provides flexible, specialist teams embedded under your direction, delivering outcomes without overheads or IP risk.

The result is simple: the client successfully modernised their legacy systems, maintained full control, and retained critical knowledge — all while staying on time and on budget. For enterprises navigating complex transformation projects, PBR isn’t just an option; it’s a smarter, more effective way to get things done.
