6 Common Mistakes to Avoid When Developing a Data Strategy


In a tech-driven industry, having a solid strategy is essential for success. Organizations that invest in a clear, well-structured approach to data are better equipped to protect sensitive information and unlock the full potential of their machine learning (ML) models.

A thoughtful strategy ensures data is accessible and aligned with business goals, which leads to more reliable insights and faster, smarter actions. It also builds a stronger security framework by addressing compliance, access controls and governance from the ground up. Most importantly, it provides consistent and high-quality information to train powerful ML models that can drive innovation across departments.

1. Underestimating Data Governance and Security

Overlooking compliance, access control and data ownership exposes companies to serious risks beyond technical issues. In 2024, the average breach cost for U.S. companies reached $9.36 million – highlighting how expensive poor planning can be.

When security isn’t prioritized, businesses become vulnerable to attacks, insider threats and penalties for noncompliance with regulations. A weak strategy often leaves gaps in how sensitive information is stored and protected. That’s why building security and governance frameworks into an organization’s strategy from day one is critical. They ensure accountability, transparency and resilience as ecosystems grow.

2. Collecting Data Without a Plan

Not all data is valuable – collecting everything without a clear plan can create more problems than solutions. When organizations try to gather every possible data point, they end up with cluttered systems, higher storage and security costs, and a sea of irrelevant information that’s tough to navigate. In fact, 80% of a data professional’s time is spent finding and preparing information rather than analyzing it or generating insights.

This slows analytics workflows and weakens machine learning models by introducing noise and unnecessary features. A strong strategy should focus on quality over quantity – prioritizing relevant, well-structured data that directly supports the organization’s goals. By narrowing in on what truly matters, teams can work faster, smarter and more securely.

3. Not Defining Clear Data Ownership

When data roles and responsibilities aren’t clearly defined, confusion over who owns what quickly arises. This lack of accountability can lead to inconsistent quality and delays in decision-making. Without a clear chain of ownership, teams may duplicate efforts or overlook critical errors that impact everything from reporting accuracy to machine learning outcomes.

That’s why it’s essential to establish clear roles early on in a strategy. Assigning dedicated stewards helps ensure everyone knows who is responsible for managing, validating and maintaining the integrity of key data assets. Clear ownership allows teams to collaborate more effectively and keep processes running smoothly.

4. Ignoring Business Objectives

Failing to align data initiatives with clear business goals is a costly misstep that can drain time, money and momentum. When teams dive into projects without a defined purpose, they often invest heavily in efforts that don’t move the needle. Companies usually focus on squeezing short-term customer revenue rather than using insights to build better, long-lasting relationships. This is especially prevalent in the consumer goods market, where companies are 1.7 times more likely to do so.

A strong strategy should always tie back to measurable outcomes – boosting customer retention, reducing risk or improving operational efficiency. Starting with the end in mind can ensure every dataset and model answers a meaningful business question and delivers real value.

5. Skipping Data Quality Checks

Machine learning models and analytics are only as good as the data that powers them, and that makes quality a nonnegotiable priority. Roughly 80% of the information organizations collect is unstructured, so the risks tied to messy inputs are higher than ever. Inconsistent formats, duplicate entries or missing values can easily weaken model accuracy and lead to decisions based on flawed insights.

Even the most advanced algorithms struggle to deliver value when trained on unreliable data. That’s why it’s critical to implement regular validation and cleansing processes as part of a strong strategy. Clean, accurate and timely information ensures models perform at their best and that analytics reflect the reality leaders must act on.

6. Leaving Out the Right Stakeholders

When a strategy is developed in isolation, it often misses the mark by overlooking the practical needs and insights of those who rely on it daily. Real-world success depends on input from across the organization – data scientists, engineers, compliance teams and business leaders bring unique perspectives that help shape a more effective, realistic approach.

Ignoring this collaboration can create costly blind spots, especially in cybersecurity, where 68% of security leaders say talent shortages expose their companies to greater risk. Involving technical and nontechnical stakeholders in planning allows businesses to build a comprehensive, scalable strategy aligned with broader goals.

Build Smarter From the Start

Organizations should take time to audit their current strategy and identify any gaps in quality, security or alignment with business goals. Fixing these blind spots early creates a stronger foundation for future growth and more reliable results.
