What’s the latest in data-driven intelligence?

Across the public sector, the pressure to support data-driven decision making has never been greater. Whether you are in a local authority, an NHS body, or a central government department, the expectation is clear: use your data, demonstrate your impact, and make better decisions faster.

So when teams start investing in performance dashboards, it's understandable that the conversation quickly turns to software. Which platform should we use? Tableau, Power BI or another? Which is better for the government?

These are reasonable questions. But they are often the wrong place to start.

The dashboard isn't the strategy

Imagine this: a public sector team has just invested in a new visualisation platform. Licences are purchased, training is booked, and a handful of dashboards are built. Six months later, those dashboards are barely used. Senior leaders still ask for data by email. Decisions are still made on instinct and spreadsheets. And when reports do get read, they are often pages of explanatory text rather than the data itself - making it hard to spot what actually matters or track how things are changing over time.

Sound familiar? It happens more often than it should and the selected platform is rarely the problem.

Building performance dashboards that genuinely support data-driven decision making in government or the public sector requires something the software can't provide on its own: analysts who understand the audience, the context and the question being asked before they open the tool.

What good looks like - regardless of dashboard or visualisation platform

A skilled data analyst working in a public sector environment doesn't begin by choosing a chart type. They begin by asking: who is this dashboard for and what decision does it need to support?

This is something the Ministry of Housing, Communities and Local Government (MHCLG) took seriously when building their own internal performance dashboard. Before writing a line of code or choosing a chart type, their team attended delivery management meetings to observe how existing reports were actually being used and what senior leaders genuinely needed from them. What they found was instructive: senior civil servants weren't looking for reassurance about things on track. They primarily wanted to know where their intervention might be required. Everything else was noise.

A frontline service manager reviewing capacity needs something different from a director preparing a board report. A policy team tracking outcomes needs a different view from a finance team monitoring spend. Getting that right by understanding the audience and designing around their needs is what makes a performance dashboard genuinely useful rather than technically impressive.

The best analysts bring this thinking to every build. They invest time understanding the data model - knowing not just what fields exist, but how data is entered, how it relates to other data, and which of it actually matters to the people reading the report. They translate complex operational data into clear, honest, actionable views. They resist the temptation to include every available metric. They write labels that make sense to a non-specialist at 8am on a Monday. And they iterate with stakeholders until the dashboard earns regular use.

None of that lives in the software.

Where Tableau and Power BI really differ

That said, platform choice does matter, but more so practically, if not fundamentally. For public sector organisations, the decision usually comes down to environment and scale.

For public sector organisations already running Microsoft 365 infrastructure, which covers much of central and local government and the likes of the NHS, Power BI's native integration can offer a practical advantage. Dashboards embed into Teams and SharePoint without additional configuration and access management aligns with existing identity frameworks. Tableau can achieve similar integration, but may require additional display licences to scale that access broadly across an organisation, which is worth factoring in when thinking about how widely you want performance dashboards to be used.

Tableau tends to suit teams doing more investigative, exploratory analytical work. Its visual flexibility and fluid interface reward experienced analysts who need to interrogate complex data before presenting findings. For specialist analytics functions, it remains a highly capable tool.

Some public sector organisations find value in using both: Power BI for operational and organisation-wide performance reporting for public services, Tableau for deeper analytical work. That's not a compromise, it's a sensible reflection of the different needs that exist within a large, complex organisation.

The real enabler of data-driven decision making in government

The most valuable conversation in public sector data teams isn't really about which platform to use. It is about how to build and sustain the analytical capability to make any platform work to its full potential.

Building a culture of data-driven decision making requires more than good software. It requires analysts who understand the organisation's priorities and can connect data to them meaningfully. It requires leaders who trust the dashboards they're shown and know how to act on them. It requires data foundations - quality, governance, consistency - that make the numbers in those dashboards reliable in the first place.

When those things are in place, performance dashboards become genuinely powerful. And the good news is that many public sector organisations already have strong foundations to build on - the opportunity is in making the most of them.

Building dashboards that actually get used

For public sector teams looking to improve the impact of their performance or public service dashboards, the most valuable investment is rarely a new tool. It is developing analysts who ask better questions, understand their audience, and design with the end user in mind - whether that end user is a ward manager, a senior civil servant, or an elected member.

The platform is the medium. The analyst is the craft. And data-driven decision making in government depends far more on the latter than most platform conversations give it credit for.

Butterfly Data works with public sector organisations to build analytical capability, improve data foundations, and design performance dashboards that people actually use. Get in touch to find out how we can help.

Data is undoubtedly one of the government's most valuable assets. Whether it is policymaking and service delivery or public trust and transparency, the quality of government data directly affects outcomes for citizens and the effectiveness of public administration. However, many public sector organisations still struggle with inconsistent, incomplete or outdated data, which undermines evidence-based decision-making across departments.

Improving government data quality isn’t just a technical task. It should be a strategic priority that touches governance, processes, skills, culture and technology. This simple guide gives some practical steps government data professionals can take to raise the standard of their data and build confidence in how it’s used.

Why data quality matters in government

Good quality data is essential in the public sector because it:

· Enables accurate decisions in policy, budgeting and delivery. Poor data can misguide planning and resource allocation.

· Supports transparency and accountability to citizens, regulators and other stakeholders.

· Reduces risk, waste and inefficiency by preventing errors and duplication.

· Ensures compliance with standards, metadata requirements and legal frameworks (e.g. GDPR).

· Enhances interoperability across government systems and agencies.

The UK Government Data Quality Framework emphasises that poor quality government data undermines public outcomes and must be managed proactively, rather than reactively.

Core dimensions of high-quality government data

Government data quality should be assessed across six key characteristics, as outlined by DAMA UK as part of DAMA-DMBOK framework:

1. Completeness: Are all required fields present and meaningful?

2. Validity: Does the data conform to defined standards and formats?

3. Consistency: Are the same rules applied across datasets and systems?

4. Accuracy: Does the data reflect the real world correctly?

5. Timeliness: Is the data up-to-date and available when needed?

6. Uniqueness: Are records free of unnecessary duplicates?

These dimensions help government agencies understand where quality is lacking and prioritise improvements accordingly.

There's more information on these in our 'What does good data look like?' whitepaper.

7 steps to improve government data quality

1. Establish strong data governance

Quality improvements must be backed by clear governance structures. This includes defined roles (data owners, stewards, custodians), policies and accountability. Governance ensures consistency in how data is created, maintained, shared and used across departments.

· Define data ownership for each key dataset.

· Set policies on data naming conventions, classifications and standards.

· Embed quality KPIs in governance documentation.

Clear governance helps ensure data quality isn’t treated as a technical afterthought but an organisational priority.

2. Know your critical data assets

Not all data is equal. Government departments should:

· Identify high‑impact datasets that support major policy decisions or service delivery.

· Prioritise quality improvements based on risk and importance.

· Develop bespoke quality plans for each dataset.

This approach ensures resources are focused where they matter most first.

3. Develop a formal Data Quality Action Plan (DQAP)

A DQAP provides a roadmap to systematically raise quality by:

· Identifying critical data and quality standards.

· Assessing current data quality levels.

· Setting measurable targets and timelines.

· Assigning responsibilities and review cycles.

Government guidance recommends documenting findings and using dashboards to monitor progress over time.

4. Standardise data collection and handling

Errors often enter a system at the point of data capture. Standardised forms, validation rules and automated checks can reduce manual errors and ensure uniform data entry across teams and services.

Examples of this include:

· Use pre-defined value lists and structured formats.

· Implement automated data validation in citizen service forms.

· Use drop-down menus and input constraints where applicable.

Standardisation improves consistency and trust in datasets.

5. Automate quality monitoring and reporting

Automation can help simplify ongoing quality assurance:

· Implement automated quality checks and validation routines.

· Use data quality dashboards to surface problems early.

· Set up alerts for anomalies or missing critical fields.

Real‑time observability helps departments detect issues quickly rather than discovering errors after decisions have been made.

6. Invest in metadata and documentation

Metadata (information about your data) is crucial in government settings:

· Document the origin, meaning and lifecycle of datasets.

· Explain how data is collected, transformed, and used.

Good metadata helps users assess whether data is “fit for purpose” and supports interoperability across systems.

7. Build a data quality culture

Data quality is not just a technical problem, but also a cultural one. Departments with healthy data cultures share some common traits:

· Leaders understand why quality matters.

· Teams proactively address issues before they escalate.

· Quality practices are embedded early in data lifecycles.

· Regular training and upskilling opportunities.

Advanced practices for government data quality

Besides the above basics, government agencies can accelerate improvements by adopting modern, proactive practices (which is also where external support from specialists like Butterfly Data can make a difference).

These include:

· Data lineage and provenance: Tracing where data came from and how it has changed over time boosts transparency and understanding.

· Reproducible analytical pipelines: Developing automated, repeatable analysis workflows reduces variability and errors.

· Cross‑agency standards alignment: Aligning data definitions and formats across the public sector enhances data interoperability and integration.

· Leverage analytics and AI tools: Modern platforms enable predictive quality checks, anomaly detection, and pattern analysis to catch issues before they affect decisions.

Benefits of improving government data quality

Investing in data quality has measurable returns:

· Better informed policy decisions.

· Increased operational efficiency.

· Improved public trust and transparency.

· Easier compliance with regulations and standards.

· Reduced cost of rework and error correction.

High‑quality data empowers governments to serve constituents more effectively and supports a transparent, accountable data‑driven public sector.

Final comments

Improving government data quality is of strategic importance, not a one‑off project.

By grounding your efforts in governance, dimensions of quality, automation and culture change, you help your department make smarter decisions, deliver better outcomes and build trust in your public data assets.

Whether you’re a data steward, analyst, programme manager or senior leader, the steps above provide a practical roadmap to elevate your government’s data quality and make better use of this most critical asset.

Public‑sector organisations in the UK are under growing pressure to modernise systems, maximise the value of data, and deliver efficient, innovative services - all while adhering to strict procurement rules. Procurement frameworks provide a compliant, cost‑effective, and streamlined route for public bodies to access specialist data consultancy, cloud services, AI solutions, and broader technology services.

With the enactment of the Procurement Act 2023, the public procurement landscape has been overhauled. The Act aims to simplify and modernise procurement, ensuring public funds deliver the greatest public benefit, while improving transparency and encouraging access toa wider pool of suppliers, particularly SMEs such as Butterfly Data.

For a data consultancy like us, being on multiple frameworks means we are well-positioned to support public‑sector organisations efficiently, while remaining fully compliant with the latest regulations.

Key benefits of public sector frameworks for data and technology

Faster procurement

Under framework arrangements, public-sector organisations can “call off” services from pre-vetted suppliers rather than run a full tender process each time. This substantially reduces procurement lead times and speeds up project start dates. For initiatives like cloud migration, data analytics platform builds or AI implementation, this speed is often crucial to success.

Cost‑effective delivery

Frameworks reduce administrative burden and enable economies of scale. By pre-agreeing terms, pricing, and supplier criteria, public bodies can secure high-quality data or tech services with minimal overhead to deliver strong value for money.

Compliance, transparency and assurance

The Procurement Act 2023 defines clear legal parameters for public procurement. Frameworks fall under its scope: Section 45 and following set out how frameworks and any “call-off” contracts awarded within them must operate.

Through a framework, public-sector clients can be confident that suppliers meet rigorous standards around fairness, equality of treatment, transparency, value for money, and public benefit.

Access to innovation and specialist expertise

Frameworks give public authorities rapid access to suppliers who specialise in emerging technologies: cloud engineering, data platforms, legacy-modernisation, AI, data analytics and more. This allows organisations to adopt modern, future‑proof solutions without procurement delays or compliance risk.

Long-term and scalable partnerships

Many public‑sector challenges require more than a single project - whether modernising legacy systems, migrating data, adopting AI, or building new analytics pipelines. Frameworks support long-term engagement: once on a framework, a supplier like Butterfly Data can collaborate over multiple phases, helping organisations evolve over time.
