When is it time to invest in data mapping software?

Depending on the size of your project or company, it might be possible to keep up with manual data mapping, via spreadsheets or otherwise. However, chances are data mapping tools will be a big relief.

Here are a four key turning points that should trigger the start of a software search:

1. You’ve hit a wall with manual data projects

If you’ve tried and failed at data mapping in the past, it might be time to take your infrastructure up a notch by engaging data mapping software. While manual data mapping can work for extremely small and simple companies, if you’re a larger or evolving company — your manual data mapping will probably continue to fail.

2. Your data maps go stale too quickly

Data mapping requires constant upkeep. Because your data is always growing and changing, if you don’t have an automated solution, it’s easy for your output to become outdated. Manual data map updating is a massive time drain, so investing in a tool is a smart allocation of resources.

3. You’ve got a team of 3+ working on it

If data mapping is a priority to your business, you’re going to have a larger team dedicated to making it happen. However, a larger team also proves that data mapping is worth resource investment. The smartest way to take advantage of your resources is to engage software to carry some of the load for you and your team.

4. You need better reporting or insights

If you’re looking at your data and feeling confused or hoping to get a better answer to some of your data-related questions, grabbing a data mapping software is a great start to gaining clarity.

What to define before comparing data mapping tools

The first step to finding the right tool isn’t to start scheduling calls with every data mapping software on the market. Instead, you’ll need to answer a few questions internally about your company’s data mapping needs and wants.

What matters more: breadth or depth?

While every company wants a magic bullet solution that offers total breadth and depth, the reality is that you’re going to have some trade-offs. Sit down with your team and identify the core issues you want to solve. 

Do you want a broader-reaching data map that lacks some detail, or would you prefer a deep dive into a few of your databases? Knowing your breadth versus depth priorities will help lead your software decision-making.

Where does your data live?

Where your data lives will dictate what software pairs well with your data organization. Does your data live in SaaS applications, or is it all in a simple database? How many different applications are you using? You’ll want to be clear about your data storage before heading into software conversations.

What is your primary issue or challenge?

Again, while it’s every company’s dream to find an all-encompassing software that checks every box, it’s just not the reality of the data mapping landscape. Certain software addresses some concerns better than others, so clarity on your primary challenge is important. Here are a few potential priorities your company may have:

• Reporting. You’re interested in getting the most information from the data you’ve collected and channeled into your data map. You want to slice and dice it, interrogate it, and pull analyses out of your data at every level
• Discovery. You want a high-level understanding of the data you’ve collected. What pools of data has your company collected? You want to see it laid out in a broad, but not particularly deep, manner
• Collaboration. You want your data to aid in collaborative efforts between stakeholders in different departments. You’d like to optimize processes and facilitate a smooth workflow with your data map

Clarifying your priorities is going to help drive decisive software conclusions. By identifying what you’d really like your tool to do, you and your team can move through the weeds quickly to identify the right tool for your company.

What data mapping software can and can’t do

Before you start exploring the software market, it’s important to understand the reality of data mapping tools. Especially if data and data mapping are outside your area of expertise, understanding software abilities and limitations is a valuable way to appropriately align your expectations. While innovation is always happening, here’s a quick overview of the state of data mapping tools in 2024.

✅ What can data mapping software do?

Data mapping software can do the following:

• Data discovery
• Data classification
• Data categorization
• Discovery for residency
• Prioritization of work
• Facilitation of human workflow and collaboration
• Unstructured data discovery

An important note on the last bullet: unstructured data discovery. While some data mapping software is capable of conducting unstructured data discovery, it can be cost-prohibitive depending on your expectations for scope. If you have expectations of reading every line of text in every PDF document, be prepared to pay a very high cost. It’s worth considering if taking a sample from various locations will satisfy your need to evaluate the risk.

⚠️ What can’t data mapping solutions do?

Auto data flow maps

‍Because your data ecosystem likely exists in multiple spaces, it’s nearly impossible for software to build an automated data flow map. This is often a buyer's expectation, and it’s important that you understand the difficulty of this task and the likelihood that your tool will not be able to do it. If a vendor tells you this is possible, you need to dig into the details. In nearly all cases, it’s simply not a realistic expectation in the face of modern business data locations and complexity. 

Knowledge of business context

No matter how smart the tool is, it won’t know your exact company’s comprehensive business context. Human participation in your data mapping remains a must, even after software implementation.

Auto building assessments (e.g. DPIA)

As is the case with business context limitations, your data map tool cannot automatically fill out assessments. Answers are subjective, so it’s unrealistic to expect a machine to be able to produce automated responses.

Useful “magic” risk scores

Loads of tools promise risk assessments, and many can be beneficial. However, we’re generally skeptical of a simple risk score that promises to capture all the complexities of your data map.

Essential reminders for the vendor evaluation process

Now that you have a good idea of your company’s priorities and a strong handle on realistic expectations for technology capabilities, it’s time to head into conversations with data mapping software vendors.

As you start lining up demo calls and enrolling stakeholders, it’s easy to get caught up in shiny objects and interesting features. But remember! Shiny objects don’t matter if they don’t come back to your specific challenges. 

‍How to evaluate data mapping software vendors

Once you know your needs, use these questions to evaluate vendors:

• Does the tool integrate with your current data stack?
• Is there a clear implementation roadmap aligned with your timeline?
• How does the vendor treat you during the sales process?
• Is the vendor early-stage and agile, or late-stage and stable?
• Are you looking for mapping, discovery, or both?
• Do you know how you’ll operationalize the platform internally?

Keep one central question in focus throughout: What problem are we trying to solve?
