    Queen’s Award-Winning Delivery Approach

    Underpinning our delivery success is BJSS Enterprise Agile. Based on 30 years of technology delivery experience, Enterprise Agile is designed to accommodate the realities and constraints faced by large organisations delivering enterprise-scale systems.

    The approach is designed to accommodate the realities and constraints faced by large organisations delivering enterprise-scale systems and is founded on these principles:

    • Risk-first: Prioritising change based on risk profile
    • Sustainability: Building resilient solutions that can easily support change well into the future
    • Quality built-in: Embedding quality from the outset
    • Transparency: Clarity throughout the delivery process
    • Innovation: Thinking beyond the usual solution
    • 'Necessary and Sufficient': Doing just enough of the right things.


    How we deliver technology is as important as what we create together – and it’s what makes BJSS different.

    One-team Ethos


    Our teams love to work in blended environments, collaborating with our clients and other suppliers as much as they do together. Our T-shaped experts work with you to create multi-discipline delivery teams with the skills and freedom to deliver and operate production-ready software at scale. We will work with your teams to support their learning and development, ensuring that you have the skills necessary to be self-sufficient.

    End-to-end Focus


    Our services will support you from idea through to production operations at scale, whether a global enterprise or an innovative scale-up. We can help you turn opportunities and ideas into solutions, design them, build them, scale them and operate them - whether your model is ‘you build it, you run it’ or managed service.
