As organizations collect more data, understanding how to utilize it becomes paramount, driving the need for nuanced data analysis and interpretation. Data without analytics doesn’t make much sense, but analytics is a broad term that can mean a lot of different things depending on where you sit on the data analytics maturity model.Modern analytics tend to fall in four distinct categories: descriptive, diagnostic, predictive, and prescriptive. How do you know which kind of analytics you should use, when you should use it, and why?Understanding the what, why, when, where, and how of your data analytics through data analysis helps to drive better decision making and enables your organization to meet its business objectives.In this blog, we cover:What is Descriptive Analytics?↵How Do You Get Started with Descriptive Analytics?What is Diagnostic Analytics?↵How Do You Get Started with Diagnostic Analytics?↵What is Predictive Analytics?↵How Do You Get Started with Predictive Analytics?↵What is Prescriptive Analytics?↵How Do You Get Started with Prescriptive Analytics?↵Learn More About The Four Types of Analytics and How They Drive Better Business Decisions. Four Types of Analytics Descriptive Analytics What is Descriptive Analytics?Descriptive analytics answer the question, “What happened?”. This type of analytics is by far the most commonly used by customers, providing reporting and analysis centered on past events. It helps companies understand things such as:How much did we sell as a company?What was our overall productivity?How many customers churned in the last quarter?Descriptive analytics is used to understand the overall performance at an aggregate level and is by far the easiest place for a company to start as data tends to be readily available to build reports and applications.It’s extremely important to build core competencies first in descriptive analytics before attempting to advance upward in the data analytics maturity model. Core competencies include things such as:Data modeling fundamentals and the adoption of basic star schema best practices,Communicating data with the right visualizations, andBasic dashboard design skills. How Do You Get Started with Descriptive Analytics?It’s likely you’ve adopted some form of descriptive analytics internally, whether that be static P&L statements, PDF reports, or reporting within an analytics tool. For a true descriptive analytics program to be implemented, the concepts of repeatability and automation of tasks must be top of mind. Repeatability in that a data process is standardized and can be regularly applied with minimal effort (think a weekly sales report), and automation in that complex tasks (VLOOKUPS, merging of excel spreadsheets, etc.) are automated—requiring little to no manual intervention. The most effective means to achieve this is to adopt a modern analytics tool which can help standardize and automate those processes on the back end and allow for a consistent reporting framework on the front end for end users.Despite only being the first pillar of analytics, descriptive analytics also tend to be where most organizations stop in the analytics maturity model. While extremely useful in framing historical indicators and trends, descriptive analytics tend to lack a tangible call to action or inference on why something occurred which leads us to the next pillar of analytics: diagnostic analytics.Low value + high riskSlightly low value + slightly high riskMedium value + medium riskSlightly high value + slightly low riskHigh value + low riskCHAOTICREACTIVEDEFINEDMANAGEDOPTIMIZEDNo formal analytic structureNo formal integrated enterprise reportingNo formal integrated enterprise reportingIntegrated enterprise analyticsIntegrate enterprise analytics (including advanced analytics)No analytics management/occurs in silosAnalytics management is departmentalizedAnalytics management is departmentalizedAnalytics management and processes existStrong analytics management and processesEmployees' analytic capabilities varyEmployees' analytic competencies varyEmployee analytics competencies varyKPIs focus on future outcomes: measures leading indicators that provide prescriptive changes (e.g. how does changing x, y, and z impact outcomes?)KPIs focus on predictions: provide strong confidence levels for taking business actionsKPIs undefined: based on ad hoc & chaotic metricsKPIs focus on the past: asking what happened last week/month/yearKPIs focus on present metrics/real-time: asking what is happening today and whyLeveraging internal and external dataData science is operationalizedLow or mixed confidence in reportsDefined key metrics shown within dashboards and scorecardsMachine learning and AI analysis are used to project KPIsThe analytics maturity model—which has five levels—demonstrates where an organization is in its ability to make data-driven decisions, as well as also act on them.Diagnostic Analytics What is Diagnostic Analytics? Diagnostic analytics, just like descriptive analytics, uses historical data to answer a question. But instead of focusing on “the what”, diagnostic analytics addresses the critical question of why an occurrence or anomaly occurred within your data. Diagnostic analytics also happen to be the most overlooked and skipped step within the analytics maturity model. Anecdotally, I see most customers attempting to go from “what happened” to “what will happen” without ever taking the time to address the “why did it happen” step. This type of analytics helps companies answer questions such as:Why did our company sales decrease in the previous quarter?Why are we seeing an increase in customer churn?Why are a specific basket of products vastly outperforming their prior year sales figures?Diagnostic analytics tends to be more accessible and fit a wider range of use cases than machine learning/predictive analytics. You might even find that it solves some business problems you earmarked for predictive analytics use cases. How Do You Get Started with Diagnostic Analytics?Being at the diagnostic analytics phase likely means you’ve adopted a modern analytics tool. Most modern analytics tools contain a variety of search-based, or lightweight artificial intelligence capabilities. These features allow for detailed insights a layer deeper (for example: the Key Drivers visualization in Power BI, or Qlik’s search-based insight functionality). To be clear, these are an effective lightweight means to address diagnostic analytics use cases but are not a means to a full-scale implementation. Software vendors like Sisu have built their core business around addressing diagnostic analytics use cases (what they call “augmented analytics”) and are a great bet.Diagnostic analytics is an important step in the maturity model that unfortunately tends to get skipped or obscured. If you cannot infer why your sales decreased 20% in 2020, then jumping to predictive analytics and trying to answer “what will happen to sales in 2021” is a stretch in advancing upward in the analytics maturity model.Have a data strategy that isn’t delivering?Talk to an expert about your data strategy needsPredictive AnalyticsWhat is Predictive Analytics?Predictive analytics is a form of advanced analytics that determines what is likely to happen based on historical data using machine learning. Historical data that comprises the bulk of descriptive and diagnostic analytics is used as the basis of building predictive analytics models. Predictive analytics helps companies address use cases such as:Predicting maintenance issues and part breakdown in machines.Determining credit risk and identifying potential fraud.Predict and avoid customer churn by identifying signs of customer dissatisfaction.How Do You Get Started with Predictive Analytics?At the outset of any predictive analytics build, three core elements need to be established:Identify a problem to solve,Define what is you want to predict, andState what you will achieve by doing so.To start you should collect existing data, organize data in a useful way to allow for data modeling, cleanse your data and review overall quality, and finally determine your modeling objective.While modeling takes up the spotlight in predictive analytics, data prep is a crucial step that needs to happen first. This is why organizations with a rock-solid foundation in descriptive and diagnostic analytics are better equipped to handle predictive analytics. Simply put, the time and effort to prep, transform, and ensure data quality for retrospective reporting has already taken place. The groundwork should be relatively well laid to quickly identify and leverage data for the modeling phase. I always encourage customers with well-defined KPIs and business logic in a specific business reporting area (think sales reporting for example) to use that as the first predictive analytics use case. The goal is to derive value quickly, and there is no better place to start than an area where you know data is well defined and of high quality.Predictive analytics is the opening to the next step—prescriptive analytics.Prescriptive AnalyticsWhat is Prescriptive Analytics?Prescriptive analytics is the fourth, and final pillar of modern analytics. Prescriptive analytics pertains to true guided analytics where your analytics is prescribing or guiding you toward a specific action to take. It is effectively the merging of descriptive, diagnostic, and predictive analytics to drive decision making. Existing scenarios or conditions (think your current fleet of freight trains) and the ramifications of a decision or occurrence (parts breakdown on the freight trains) are applied to create a guided decision or action for the user to take (proactively buy more parts for preventative maintenance).Prescriptive analytics requires strong competencies in descriptive, diagnostic, and predictive analytics which is why it tends to be found in highly specialized industries (oil and gas, clinical healthcare, finance, and insurance to name a few) where use cases are well defined. Prescriptive analytics help to address use cases such as:Automatic adjustment of product pricing based on anticipated customer demand and external factors.Flagging select employees for additional training based on incident reports in the field.Prescriptive analytics primary aim is to take the educated guess or assessment out of data analytics and streamline the decision-making process.How Do You Get Started with Prescriptive Analytics?Prescriptive analytics is commonly considered the merging of descriptive, diagnostic, and predictive analytics. Getting started isn’t so much a step-by-step list but rather the time and effort up front to build your competencies within the analytics maturity curve.Simply put, there is no starting point in prescriptive analytics without the requisite first three pillars of modern analytics being established first. If you’re ready for prescriptive analytics, then quantifying your call to action and the underlying criteria will be the first requirement. For example: if the use case is to call corrective action for an employee (i.e. – additional training based on poor performance) then the factors that necessitate this action must be firmly established and the action itself must be clearly defined.Moving through the data analytics maturity model shouldn’t be a race. Knowing how each kind of analytics helps you better understand your data and how to use it move your business objectives forward is key to realizing the return on investment in data and analytics.
