Strengthen data quality

Understand how starting with good data quality improves decisions and AI outcomes

Data is one of the most important inputs for modern business systems, including AI.

You may already rely on data created or collected through daily tasks, such as:

  • responding to customer enquiries
  • selling and managing stock
  • scheduling staff
  • managing budgets, payroll and cash flow
  • marketing your business.

AI can help you get more value from your data by turning it into insights that support better workflows and business growth.

How AI uses data

AI systems can analyse large amounts of information quickly. This allows you to use data for tasks that would otherwise take a lot of time to do manually.

Data can be structured (such as records in a system or spreadsheet) or unstructured (such as emails and documents).

Regardless of format, good data management is important. It helps you:

  • identify trends or issues earlier
  • provide better customer service
  • meet privacy, cyber security, contractual and intellectual property obligations
  • reduce time spent on repetitive tasks
  • support better informed decisions
  • scale services without increasing effort at the same time.

Even with AI and good data, you still need to place people at the centre. 

The cost of bad data

An AI system depends on the information you give it. If data is incomplete, outdated or inconsistent, the results will reflect those weaknesses.

Poor data quality can lead to:

  • incorrect or misleading outputs
  • automation that behaves in unexpected ways
  • breaching your legal obligations
  • decisions that are hard to explain
  • lower confidence from staff or customers.

Understand the 1‑10‑100 rule

The 1-10-100 rule, first developed by Labovitz  et al. (1992), highlights why preventing data issues early costs far less than fixing problems later.

The $1 prevention

It costs relatively little to prevent data issues at the start. In practice, this means checking that data is accurate, complete and structured before you use it in an AI system.

The $10 correction

It costs around 10 times more to fix problems once poor-quality data is already in the AI system. In practice, this means extra time spent on cleaning data, correcting mistakes or re-running processes. 

The $100 failure

It costs around 100 times more when an AI system is trained on bad data. In practice, this is when an AI tool produces biased or inaccurate outputs, or fails when it matters most. It often damages trust and can lead to serious consequences.

Example: How bad data creates confusion for customers and staff

A small clothing retailer uses an AI tool to answer customer questions and manage stock across its online and in-store systems.

Product and inventory data aren’t consistent across these systems. Because of this, the AI gives wrong information about what's in stock and customers receive conflicting messages. Staff end up checking real stock in store and at their warehouse.

Over time, trust in the system and confidence from customers drop. Even though AI could save time and effort, poor data quality prevents it from providing reliable value and impacts business revenue. Depending on the information provided to the customer, the business may be at risk of misleading and deceptive conduct under Australian Consumer Law.

Good data improves outcomes

Organisations that treat data as a core asset are better positioned to use AI effectively.

You don’t need complex systems or large teams. Start by:

  • understanding what data you have and where it comes from
  • keeping important data accurate and up to date
  • being clear about who's responsible for managing data
  • collecting, using and disclosing data in accordance with your organisation's privacy policy and Australian Privacy Principles
  • protecting data with cyber security processes so that sensitive information isn't shared by accident
  • using data in line with data usage rights including intellectual property, privacy, confidentiality and contractual rights
  • monitoring for leaks of any personal or sensitive information.

When you manage data with care, AI systems are more reliable, easier to govern and more likely to deliver useful outcomes.
