Data-Driven Decision Making: Unlocking Smarter Choices in Business and Life
Between 2005 and 2009, Chicago had a challenging problem that the city leaders absolutely needed to solve: unacceptable rates of foodborne illnesses. The city had limited resources for making health inspections in food service spots. Restaurant inspections were generated from complaints or randomly, but they were ineffective in curbing the problem.
When the city turned to data, the game changed. Chicago’s Department of Public Health entered a partnership with data scientists to develop a predictive model. They analyzed things like weather patterns, social media posts, and a history of health code violations. Using the data points gathered, they were able to identify which restaurants were most likely to be in violation of health codes. By focusing inspections on those restaurants, they were able to identify critical health violations day sooner than before, which reduced the number of foodborne illnesses. Data-Driven Decision Making (DDDM) provided the information, gathered from a number of different – often unlikely – sources, to generate effective actions. We’re going to examine what DDDM involves and how it can provide better actionable information.
WHAT IS DATA-DRIVEN DECISION MAKING?
Data-Driven Decision Making (DDDM) is an approach that emphasizes using data and analysis instead of intuition to inform business decisions. Some of the data sources can include customer feedback, market trends, and financial data to guide the decision-making process. This method can help organizations make more accurate decisions, and, at least as important, more objective decisions, which will produce better outcomes and improvements in performance.
While we don’t need to use DDDM for everyday choices, it can be a significant improvement factor in many professional and organizational contexts. In business and marketing, companies are using data to recognize market trends, customer preferences, and to measure how effective their marketing campaigns are. Healthcare data provides crucial information for patient care, medical research, and public health initiatives. Medical and research professionals use the data to help diagnose diseases, predict outbreaks, and personalize treatments. Financial institutions are able to assess risks, detect fraud, and make investment decisions because of DDDM. We would expect these sectors to make use of such a practice.
Let’s look at some groups that we may not figure would be so data-driven. Supply Chain Management uses data to optimize logistics, manage inventory, and forecast demand. It’s why UPS trucks don’t turn left. Schools and universities track student performance, improve teaching methods, and allocate resources more effectively by leveraging data points. Governments and public policy centers use data-driven insights to help them in creating policies, manage resources, and more effectively address social issues. Sports teams and athletes use data to analyze performance, develop training programs, and device game strategies. The movie Moneyball demonstrated how using statistics could produce better outcomes for the team, and Ted Williams analyzed his hitting strategy using statistics from what kind of pitches he hit, and how well he hit them. Technology development relies heavily on data from users and other software data to develop new software, improve existing software, and enhance user experiences.
THE IMPORTANCE OF USING DATA IN THE MODERN DECISION PROCESS
As we saw in the examples above, data can play a crucial role in modern decision-making processes across various fields. Data can provide a factual basis for decisions, reducing our reliance on intuition or guesses, and thus leading to more accurate and reliable outcomes. Incorporating real, verified data into the process, we can analyze it and identify potential risks, and then we can take the appropriate steps to address the risks before they become significant issues. Data also helps us identify where we have inefficiencies and cost-reduction opportunities that won’t require compromises on quality or performance. Using data, we can streamline processes and improve productivity by finding spots where bottlenecks have occurred.
TRADITIONAL APPROACHES COMPARED WITH DATA-DRIVEN APPROACHES
Without data available, we’re often left to rely on intuition, experience, and established practices, none of which is absolutely “wrong.” But we may not see things exactly as they are, our intuition could be biased, our practices may be influenced by factors that have changed. As a result, process decisions are often made on gut feelings, instincts, or historical precedents. These decisions are almost always more difficult to evaluate objectively. Regardless of what the actual results are telling us, it’s tempting to fall back to the way we’ve always done it.
Using data analysis and empirical evidence involves collecting, analyzing, and interpreting data to guide decisions. The resulting decisions are more objective and can be evaluated based on metrics and actual, measurable outcomes. “The way it’s always been done” isn’t the standard anymore; the way the data tells us to do it is the new standard. DDDM also has the advantage of not only being more accurate, but also more adaptable to new information, because the organization won’t be killing someone’s pet.
THE KEY ELEMENTS OF DDDM
The first element in making data-driven decisions is collecting the data. Data can be quantitative – numerical information like sales figures, website traffic, and survey results – or qualitative – data that describes, like customer feedback, interviews, and discussions from focus groups. One type is not necessarily better than the other, and, in fact, we require both for a complete picture of reality.
The next element is analyzing the data. There are many tools to help with this, like SPSS data analysis software, R, or Python, which are both programming languages that work exceptionally well for data analysis. There are tools like Tableau and Power BI to create visual representations of the data, which can often be more beneficial than just the raw numbers. We can also use machine learning algorithms and models to help us recognize patterns and, from those patterns, make predictions.
From the analysis of the data, we form insights from which we can take action, and action is what we’re looking for from our efforts. We can interpret the data to identify any trends, opportunities, and areas that could use improvement. We’ll be making informed decisions based on those insights. Finally, we’re going to monitor the outcomes and performance on a continuous basis, using feedback to further refine the strategies and improve our decision-making processes in the future.
CHALLENGES IN IMPLEMENTING DDDM
Challenges? Of course there are challenges. Most of my articles talk about challenges in the innovations, because forewarned is forearmed. The quality of the data is one of the most important factors in accurate decision-making. If he data incorporates bias, incomplete data, or inaccuracies, the results won’t be true. Also, we can gather so much data that we’ll never get through it all. We’ll become overwhelmed by facts and enter a state of analysis paralysis. Another concern is that it’s also not easy to shift from intuition-based models to using just data. DDDM also requires access to proper tools and trained staff, and those can be difficult to find or develop.
BEST PRACTICES FOR EFFECTIVE DDDM
You know I never finish an article with the challenges. I always drop in some encouragement that will help us overcome those challenges. One of the most important things to understand is what the objective is – what’s the thing you want to have happen from the decision? It will also be helpful to know what the Key Performance Indicators (KPIs) will be that actually measure the effectiveness you seek. Remember that we have an ethical responsibility to ensure the privacy of the data we collect, and we have a professional responsibility to secure the data and also to make sure it’s accurate. Finally, to make it work its magic, DDDM needs to involve all the stakeholders and cross-functional teams.
YOUR TURN
DDDM can help organizations pivot more quickly in emergencies. As the world shut down in 2020, having data points from their customers may have helped many small businesses find ways to serve their customer base remotely until normalcy returned. Having Large Language Models (LLMs) ingesting ever increasing data stores will offer this type of opportunities to even solopreneurs. ChatGPT and its cousins aren’t logic models – they can’t accurately tell you to do for your customers, but they can tell you what was, what is, and from the was and is, what might be.
You likely use both intuition-based and data-driven methods for making your decisions, some more often than others – how much money you need to retire to the life you want to live, where to go on vacation, when to go on vacation, how to create a fitness plan to achieve the level you’re looking for.
