The list of inevitabilities in the life of a data analyst or engineer includes death, taxes, unreasonable ad hoc requests from business stakeholders, and slow dashboards.

As you have countless times sat waiting for the loading wheel in Looker, Power BI, Tableau, or Google Analytics to stop spinning, you may have wondered…

• “Why is this dashboard so slow?” 
• “Can I make it faster?”
• “How hard would it be to build a real-time dashboard?”
• “Are real-time dashboards worth it?”

I’m here to tell you that, yes, real-time dashboards are worth it. Not only are they exceptionally useful for operational decision-making, real-time data analysis, and tracking key performance indicators (KPIs), but they’re also becoming the de facto standard for data visualization, driven by a growing trend in data engineering and data-driven software development towards providing users - both internal and external - with better user experiences powered by real-time data analytics.

Are dashboards outdated?

Despite what some might say, no. Dashboards are not “dead,” nor are they outdated or obsolete.

There’s a common misconception that dashboards aren’t necessary; we should skip the visuals and go straight to AI-powered analytics and machine learning models for automated decision-making, predictive forecasting, real-time automation, and the litany of promises that AI adherents would have us believe.

But this is a false premise, driven by those who have lost faith in dashboards that are chock full of terrible, unreliable, low-quality data.

Those who think AI is the antidote to their data-driven ailments are wrong. In reality, just like machine learning models, dashboards are becoming more and more useful as data teams in data-driven organizations continue to improve the quality, consistency, veracity, and performance of data pipelines. As data gets better, dashboards get better.

People distrust dashboards because of low-quality data. AI won't fix that.

So, no, dashboards aren’t outdated. They’re better than ever.

But why are many dashboards so slow?

Dashboards are slow because the data pipelines underpinning them are slow. In many cases, this is due to poor data design: bad queries, improper indexing, expensive aggregates saved for query time, inefficient caching, etc.

But even if your tables and SQL are in tip-top shape, your dashboards still might be a bit sluggish.

Dashboards are slow because of bad data models and tools that aren't meant for real-time.

To understand why, you can flip through the pages of enterprise data history books. From the Big Data movement to the Modern Data Stack, most data infrastructure and data tools were created to support a singular function: strategic decision-making by C-level executives.

The time horizon for boardroom decisions is far-reaching: often quarters or years. Because of this, business intelligence dashboards don’t need to be fast. It’s perfectly fine to run a report overnight and fire off a PDF to the CEO’s inbox at 7 AM the next morning.

Cloud data warehouses, business intelligence reporting tools, and the data engineers who wield them take advantage of this. They make conscious choices to trade speed for user-friendly interfaces and the ability to process large amounts of data on distributed storage and compute. These technologies weren’t built for real-time operational intelligence, automation, or interactive user experiences. The ETL/ELT pipelines that data engineers build to create business metrics and feed these tools often run infrequently, resulting in potentially out-of-date information.

But with the rise of real-time data and streaming architectures, we have an opportunity to build faster dashboards based on the freshest data. These are what we call “real-time dashboards”, and they are definitely worth it.

What is a real-time dashboard?

A real-time dashboard displays metrics or KPIs built from data that is seconds old (or fresher) as well as historical data, returns a response to new queries in only milliseconds, and can support thousands of concurrent requests without lagging.

What is the objective of a real-time dashboard?

Real-time dashboards serve two primary functions: operational intelligence and enhanced customer experiences. They enable high-speed data visualization that allows internal stakeholders and external customers to act upon the freshest data available.

Real-time dashboards can be used for internally-facing operational intelligence or externally-facing customer experiences.

Real-time dashboards for operational intelligence

Whereas business intelligence is used to make decisions on time horizons spanning quarters or years, operational intelligence is used to make day-to-day, hour-to-hour, and minute-to-minute decisions within a business.

Analysts, operations managers, and engineers can use live dashboards displaying critical KPIs to make snap decisions about how to operate the business effectively and in the moment.

Some examples:

• Sales and marketing teams at large retail companies monitor the performance of sales in real-time, optimizing advertising campaigns to drive higher conversion rates.
• Logistics managers use live dashboards to track inventory in real-time, making decisions to divert inventory where demand is higher.
• Airline technicians use real-time dashboards to track customer luggage from terminal to terminal, reducing the number of bags that get lost or misplaced.
• IT managers use real-time dashboards to identify DDoS attacks, server downtime, or performance degradations across a company's IT infrastructure.

Real-time dashboards for enhanced customer experiences

In the old days, a company’s data was mostly used for internal decision-making. Now, that data is being injected back into the product. Real-time analytics is powering differentiating user experiences, using dashboards and real-time data sources to help customers make better use of the product, increasing customer satisfaction.

Some examples:

• A bank or investment company shows its customers how their investments are performing in real time compared to historical trends. 
• A MarTech SaaS serves customers with real-time analytics on search data so that marketers can optimize SEO campaigns.
• A social media platform gives content creators real-time insight into media engagement and performance.
• A sports betting company shows live bet spreads on their media channels.

What are the benefits of real-time dashboards?

Broadly speaking, dashboards are valuable because they allow humans to make informed decisions.

An article from Harvard Business School outlines a few examples from Google, Starbucks, and Amazon. These enterprises use data visualizations to improve favorability scores for managers, pinpoint ideal store locations, and increase customer conversion rates, respectively.

What makes real-time dashboards so special is their ability to massively shorten the time to a decision and the subsequent feedback loop. In terms of business performance, this has obvious operational implications. Those with fresher, faster data can make faster decisions, generate feedback on those decisions more quickly, and iterate new solutions faster than the competition. Speed is a serious competitive advantage, and real-time dashboards increase decision-making speed.

But the benefits of real-time dashboards extend beyond business decisions and into the realm of customer experiences and product differentiation.

As I described above, real-time dashboards aren’t just used for internal stakeholders, but also for external customers. You can embed real-time dashboards into user interfaces to give users information that helps them better use the product. Real-time dashboards make a meaningful difference in improving customer satisfaction, reducing churn, and increasing customer lifetime value.

When embedded into user experiences, real-time dashboards can become powerful, differentiating features.

Said differently, dashboards are no longer tools for dropping the bottom line, but also for increasing top-line revenue through differentiation and increased customer value.

Designing Real Time Dashboards That People Actually Use

Building a real time dashboard is not just about making data update faster. It is about creating a tool that helps people act with confidence. Fresh data is only meaningful when it is presented clearly, prioritized well, and aligned with the decisions teams need to make.

This is why strong dashboards focus on clarity, intent, and usability, not just raw speed. A powerful real time dashboard starts with one question: what decision should this help someone make faster. When that question is answered, every chart, threshold, and interaction becomes easier to design.

When it is not, dashboards turn into dense walls of metrics that look impressive but rarely change anyone’s behavior. You can see applied examples of good design principles in this guide on real time data visualization.

Start with the decision, not the metric

It is tempting to assemble a dashboard by listing all the KPIs available. But real time surfaces work best when they start at the opposite end. Begin by defining the moment of action the dashboard supports.

Are you helping a team spot a sudden traffic drop, investigate a spike in latency, balance inventory in real time, or monitor onboarding friction?

Once the intended action is clear, the dashboard should elevate only the metrics directly tied to that moment. Everything else becomes secondary. This avoids noisy layouts and keeps attention on what matters when it matters.

Embrace a clear visual hierarchy

Real time dashboards need a visual structure that guides the eye without effort. Users should know instantly whether things are normal or not.

This requires a strong hierarchy: a few high signal KPIs at the top, secondary details grouped beneath them, and deeper data behind interactions rather than on the main canvas.

Color should be used thoughtfully. Real time dashboards often rely too heavily on bright alerts, which can train users to ignore them. Good dashboards reserve alert colors for true anomalies and rely on clean spacing, bold typography, and logical grouping to convey importance.

Context matters as much as freshness

A real time number without context is meaningless. A dip may look alarming, but without historical reference you do not know if it is a normal daily pattern or a real issue. A spike may be healthy growth or a data glitch.

Adding small historical markers, trailing averages, or comparisons to the same period last week turns real time metrics into real insight.

Real time dashboards benefit from blending live data and historical trends. It gives the user a fast frame of reference and prevents knee jerk reactions to normal fluctuations.

Avoid data overload by prioritizing signals

Because real time data feels exciting, teams often pack in too many metrics. That is a mistake. A dashboard does not become more useful by becoming more exhaustive. It becomes powerful by being focused.

Choosing what to exclude is just as important as what to include. Many metrics belong in analytical dashboards, not real time ones.

Real time dashboards should only display metrics where seconds or minutes matter. Everything else belongs elsewhere.

Tune refresh rates to real human behavior

A common misconception is that real time dashboards must update every second. In reality, constant flicker creates noise and distracts from the story.

The refresh interval should match how quickly humans can act and how often the metric truly changes.

Some dashboards update every few seconds. Others every 30 seconds or every minute. Some work best with event driven updates that refresh only when something meaningful happens.

The right refresh strategy makes the dashboard feel alive without becoming hectic.

Design for exploration without overwhelming the main view

Real time dashboards become far more valuable when users can explore details without cluttering the main screen.

Filters, drill downs, hover details, and collapsible sections let teams investigate anomalies without turning the primary layout into a puzzle.

This separation between overview and deep dive keeps the dashboard calm, while still providing the depth users need to solve issues.

Think in experiences, not pages

Dashboards are not static pages. They are experiences that serve different purposes depending on context. A dashboard shown on a large screen in an operations room needs to emphasize big, stable numbers.

A dashboard used by an engineer on call should highlight alerts, errors, and anomalies. A dashboard opened by a product manager benefits from interactive breakdowns and contextual comparisons.

Designing with context in mind turns real time dashboards into tools, not just displays.

Real Time Dashboards Across Roles and Industries

Real time dashboards are not limited to analytics teams. They empower multiple roles across an organization, and the impact grows dramatically when dashboards are tailored to the specific needs of each team.

Adding these perspectives expands the usefulness of any real time analytics guide, because it demonstrates how live data supports diverse workflows across operations, finance, product, marketing, healthcare, retail, and more.

Real time for operations teams

Operations is one of the clearest beneficiaries of real time dashboards. These teams often make minute to minute decisions.

They need visibility into bottlenecks, fulfillment delays, capacity constraints, and service level degradations.

A real time operations dashboard helps teams catch issues before they cascade. Early detection of anomalies in throughput, routing, delivery times, or stock ensures smoother workflows and higher service quality.

Real time visibility prevents small issues from becoming costly incidents.

Real time for product and engineering teams

Product teams rely heavily on real time insight to track adoption, usage behavior, and friction in the experience. When a new feature rolls out, real time dashboards show whether users are adopting it, how performance evolves, and where drop offs appear.

Engineers use real time views to monitor latency, errors, deployment impact, and system health.

Together, these teams use real time dashboards to diagnose issues in minutes instead of hours or days. This rapid feedback loop is invaluable for maintaining reliability and delivering better experiences.

Real time for finance teams

Finance decisions often require stability, but the visibility provided by real time dashboards can prevent surprises. Real time tracking of revenue, expenses, cash flow, and unsettled transactions gives financial teams a clear view of short term risk.

Sudden shifts in payment volume or unexpected fluctuations in cost centers become visible the moment they occur.

This level of immediacy helps financial leaders forecast more accurately, respond to anomalies early, and support other teams with data driven guidance.

Real time for marketing and revenue teams

Marketing teams operate in environments where timing is everything. A campaign can burn budget quickly if something goes wrong.

Real time dashboards show conversion changes, audience behavior, spending pace, and channel performance as they unfold.

Revenue teams benefit from the same responsiveness. They can see trends forming in real time, analyze dips or surges, and respond to demand signals immediately.

This creates a dynamic operating rhythm where teams can course correct fast and capitalize on opportunities.

Real time for retail environments

Retail is full of micro moments that influence outcomes. Real time dashboards empower store managers, ecommerce teams, and retail operations by showing stock levels, sales trends, customer behavior patterns, and in store performance indicators.

A spike in demand, a risk of stockout, or a drop in conversion becomes visible instantly.

The result is a more agile retail operation where teams can reallocate inventory, adjust staffing, or fine tune promotions in real time.

Real time for healthcare and critical services

Healthcare environments benefit deeply from real time dashboards because lives and safety are impacted by delays.

These dashboards help teams monitor capacity, patient flow, wait times, resource availability, and quality indicators as they change. Real time visibility ensures faster decisions and better outcomes.

Even outside clinical settings, real time dashboards support administrative efficiency and improve the overall experience for patients and staff.

Real time for compliance, legal, and risk

Dashboards in this domain monitor contract timelines, policy breaches, audit triggers, and regulatory requirements. When a risk condition emerges, real time visibility prevents escalation.

This proactive model replaces the old paradigm of discovering issues only after audits or scheduled reviews.

Why these perspectives matter

Different teams have different rhythms and responsibilities. Real time dashboards only deliver value when they reflect the unique pressures and workflows of the people who use them.

By incorporating cross functional examples and role specific insights, a real time analytics guide becomes far more actionable.

It illustrates how live data supports decisions at every layer of an organization and across industries where timing, clarity, and responsiveness can change outcomes.

There is also a specific example that explains how to create a real time dashboard using BigQuery, which illustrates another common architecture: bigquery real time dashboard.

How do I create a real-time dashboard?

Creating a real-time dashboard is easier than you think. You can follow this step-by-step tutorial and have a beautiful, responsive, and interactive real-time dashboard built in less than an hour.

The important thing when creating a real-time dashboard is to use tools fit for the purpose. If you’re trying to build real-time dashboards using Looker and BigQuery, PowerBI and Azure Synapse Analytics, or Tableau and Postgres, then you’re going to either struggle to make things real-time or end up paying a ton to do so.

You need to choose real-time data infrastructure that’s designed to support real-time dashboards.

What tools should I use to build real-time dashboards?

The tools for real-time dashboards can be broken down into four basic categories:

1. Real-time data collection. Use real-time data architectures and streaming platforms for real-time data ingestion to collect and process the freshest data sets.
   
   Streaming platforms like Apache Kafka, Confluent, Redpanda, and Amazon Kinesis or message queues like Google Pub/Sub or RabbitMQ allow you to capture data using event-driven architectures, ensuring you have the freshest data available for visualization.
2. Real-time data processing. Real-time dashboards require real-time data processing engines. You need to be able to filter, join, aggregate, and otherwise transform data streams as they arrive to build useful KPIs and performance metrics for your dashboards.
   
   For real-time processing, you can use real-time databases (like ClickHouse®, Apache Druid, and Apache Pinot), stream processing engines (like Apache Flink), or analytics engines (like Apache Spark), each with varying degrees of complexity.
   
   To avoid complexity, you can turn to a real-time data platform like Tinybird, which provides end-to-end real-time processing capabilities through native streaming data connectors and an intuitive SQL interface to build and publish analytics metrics for your dashboards.
3. Real-time data storage. Real-time dashboards visualize data stored in a database. That can be anything from a cloud data warehouse like BigQuery or Snowflake to in-memory key-value stores like Redis.
   
   There’s also a middle ground of real-time databases that provide the flexibility of a full online analytical processing (OLAP) engine but at speeds closer to in-memory stores. Examples here include those mentioned above (ClickHouse®, Druid, and Pinot).
4. Real-time visualization tools. Depending on your use case, classic business intelligence tools like Looker, Power BI, and Tableau might not work. For example, if you want to embed your real-time dashboard directly into a web application, you’ll be better off using a modern JavaScript framework like React or Next.js to build visualizations in the product.
   
   For some, more modern BI tools like Domo or Apache Superset can alleviate some of the pains of traditional BI tools.
