How we do software delivery

We’re proud to work with the public sector to transform its approach to software delivery. Building scalable, secure, and user-focused platforms that benefit people, places and the planet is at the heart of what we do. But how do we do that? Here, we share our framework for success, rooted in collaboration, pragmatism, and innovation.

The challenge of software delivery

Creating a robust software platform requires more than technical expertise. It’s about balancing the need for innovation with the responsibility to deliver secure, cost-effective, and scalable systems that evolve alongside user needs. For public sector organisations, this challenge is even greater. Systems must remain reliable under pressure, offer excellent value for money, and support long-term management by civil servants.

To meet these demands, we’ve fostered a culture that prioritises DevOps collaboration and embraces the 'you build it, you ship it, you run it' philosophy, ensuring engineers take full ownership of their work from development to production. This approach enhances efficiency and builds trust in the platforms we create.

Building software that works

At the heart of our software delivery strategy lies a guiding framework referred to internally as PROVE (Pragmatism, Reproducibility, Openness, Value, and Ecosystem). They help us deliver reliable, scalable, and impactful solutions.

Pragmatism: Lean software, maximum impact

We believe in keeping things simple. By embracing lean software principles, we focus on delivering the features that truly matter. 

• Streamlined processes: We eliminate unnecessary complexity to focus on the essentials.

• Constructive challenge: Teams challenge assumptions to ensure software aligns with real needs

• Iterative improvement: Regular retrospectives and feedback loops help us refine our approach.

By prioritising pragmatic solutions, we deliver systems that are not only functional but also efficient to maintain and scale.

Reproducibility: Building with confidence

Software should work the same way every time, no matter the environment. Predictability leads to reliability, so we ensure our systems are testable and reproducible at every level:

To achieve this, we focus on:

• Test-driven development: Writing tests first ensures systems behave as expected.

• Immutable infrastructure: Infrastructure-as-code guarantees environments can be recreated seamlessly, no more “it works on my machine”.

• Knowledge sharing: Comprehensive documentation ensures that future teams can confidently manage and evolve the platforms in the future.

This focus on reproducibility minimises risk, reduces downtime, and builds trust among users and stakeholders.

Openness: Sharing knowledge, building trust

We are committed to working openly, leveraging open-source software and fostering a culture of transparency. This involves:

• Collaborative problem solving: Multidisciplinary teams work together, breaking down silos, to tackle challenges more effectively.

• Community engagement: We actively participate in technical communities and open source projects, sharing lessons learned and helping others learn from our experience.

• Accessible, up to date documentation: Clear, continuously updated materials ensure that both our teams, future teams and end-users can easily understand and use our systems.

This openness not only enhances our work but also strengthens the communities we serve.

Value: Delivering early and often

We focus on quickly delivering functional, high-quality software to users while ensuring long-term sustainability.

• Maximise efficiency: Continuous integration and automated testing ensure issues are caught early, keeping development on track.

• Frequent, Incremental Releases – Small, regular deployments reduce risk and allow us to respond to changing needs.

• Maintain high standards: Proactive monitoring, performance tuning, and automated regression testing keep systems stable in production.

Focusing on delivering working software early and often, we minimise waste, adapt to user needs, and build trust in our platforms.

Ecosystem thinking: Designing for the bigger picture

Software rarely exists in isolation. Every system we build exists within a broader ecosystem. We take a systems-level perspective to optimise for holistic outcomes, ensuring:

• Scalability: Cloud-first infrastructure supports dynamic scaling as demand grows.

• Interoperability by design: Standardised API’s, formats and identifiers enable seamless integration with existing and future systems.

• Sustainability: Choosing technologies with strong ecosystems, long-term support, clear upgrade paths and adaptability.

• Security by default – We embed security at every layer, from software to architecture to deployment, ensuring our platforms are resilient to evolving threats.

By building with the bigger picture in mind, we create software that is resilient, adaptable, and future-proof.

Building a culture of excellence

Great software adapts, improves, and grows. Shaped by the people who build it and the users who rely on it. The best teams step up to this reality, continuously learning and delivering value every release.

At TPXimpact, we believe passionate people build the best products. We encourage a culture where curiosity, collaboration, and a commitment to excellence lead our actions. From iterative delivery and open knowledge sharing to secure, scalable engineering solutions, our goal is always the same: shipping high quality software that makes a difference.
