Data Storytelling: Turning Data into Insight and Action

Data storytelling sits at the intersection of data, narrative, and visuals. It’s not just about analyzing numbers or building dashboards—it’s about communicating insights in a way that people understand, care about, and can act on. In a world overflowing with data, storytelling is what transforms analysis from “interesting” into “impactful.”

This article explores what data storytelling is, why it matters, its core components, and how to practice it effectively.

1. What Is Data Storytelling?

Data storytelling is the practice of using data, combined with narrative and visualization, to communicate insights clearly and persuasively. It answers not only what the data says, but also why it matters and what should be done next.

At its core, data storytelling blends three elements:

Data: Accurate, relevant, and well-analyzed information
Narrative: A logical and engaging story that guides the audience
Visuals: Charts, tables, and graphics that make insights easier to grasp

Unlike raw reporting, data storytelling focuses on meaning and context. It connects insights to real-world decisions, business goals, or human experiences.

2. Why Is Data Storytelling Important?

a. Data Alone Rarely Drives Action

Even the best analysis can fall flat if it isn’t understood. Stakeholders don’t make decisions based on spreadsheets—they act on insights they trust and comprehend. Storytelling bridges the gap between analysis and action.

b. It Improves Understanding and Retention

Humans are wired for stories. We remember narratives far better than isolated facts or numbers. Framing insights as a story helps audiences retain key messages and recall them when decisions need to be made.

c. It Aligns Diverse Audiences

Different stakeholders care about different things. Data storytelling allows you to tailor the same underlying data to multiple audiences—executives, managers, analysts—by emphasizing what matters most to each group.

d. It Builds Trust in Data

Clear explanations, transparent assumptions, and logical flow increase credibility. A well-told data story makes the analysis feel approachable and trustworthy, rather than mysterious or intimidating.

3. The Key Elements of Effective Data Storytelling

a. Clear Purpose

Every data story should start with a clear objective:

What question are you answering?
What decision should this support?
What action do you want the audience to take?

Without a purpose, storytelling becomes noise rather than signal.

b. Strong Narrative Structure

Effective data stories often follow a familiar structure:

Context – Why are we looking at this?
Challenge or Question – What problem are we trying to solve?
Insight – What does the data reveal?
Implication – Why does this matter?
Action – What should be done next?

This structure helps guide the audience logically from question to conclusion.

c. Audience Awareness

A good data storyteller deeply understands their audience:

What level of data literacy do they have?
What do they care about?
What decisions are they responsible for?

The same insight may need a technical explanation for analysts and a high-level narrative for executives.

d. Effective Visuals

Visuals should simplify, not decorate. Strong visuals:

Highlight the key insight
Remove unnecessary clutter
Use appropriate chart types
Emphasize comparisons and trends

Every chart should answer a question, not just display data.

e. Context and Interpretation

Numbers rarely speak for themselves. Data storytelling provides:

Benchmarks
Historical context
Business or real-world meaning

Explaining why a metric changed is often more valuable than showing that it changed.

4. How to Practice Data Storytelling Effectively

Step 1: Start With the Question, Not the Data

Begin by clarifying the business question or decision. This prevents analysis from drifting and keeps the story focused.

Step 2: Identify the Key Insight

Ask yourself:

What is the single most important takeaway?
If the audience remembers only one thing, what should it be?

Everything else in the story should support this insight.

Step 3: Choose the Right Visuals

Select visuals that best communicate the message:

Trends over time → line charts
Comparisons → bar charts
Distribution → histograms or box plots

Avoid overloading dashboards with too many visuals—clarity beats completeness.

Step 4: Build the Narrative Around the Insight

Use plain language to explain:

What happened
Why it happened
Why it matters

Think like a guide, not a presenter—walk the audience through the analysis.

Step 5: End With Action

Strong data stories conclude with a recommendation:

What should we do differently?
What decision does this support?
What should be investigated next?

Insight without action is just information.

Final Thoughts

Data storytelling is a critical skill for modern data professionals. As data becomes more accessible, the true differentiator is not who can analyze data—but who can communicate insights clearly and persuasively.

By combining solid analysis with thoughtful narrative and effective visuals, data storytelling turns numbers into understanding and understanding into action. In the end, the most impactful data stories don’t just explain the past—they shape better decisions for the future.

Common Data Mistakes Businesses Make (and How to Fix Them)

Most organizations don’t fail at data because they lack tools or technology. They fail, or have sub-optimal data outcomes, because of small, repeated mistakes that quietly undermine trust, decision-making, and value. The good news is that these mistakes are fixable.

Here we outline a few of the common mistakes and how to fix them.

Treating Data as an Afterthought

The mistake:
Data is considered only after systems are built, processes are defined, or decisions are already made. Analytics becomes reactive instead of intentional.

How to fix it:
Bring data thinking into the earliest stages of planning. Define what success looks like, what needs to be measured, and how data will be captured before solutions go live.

Measuring Everything Instead of What Matters

The mistake:
Dashboards become crowded with metrics that look interesting but don’t influence decisions. Teams spend more time reporting than acting.

How to fix it:
Identify a small set of actionable metrics and KPIs aligned to business goals. If a metric doesn’t inform a decision or behavior, question why it exists.

Confusing Metrics with KPIs

The mistake:
Operational metrics are treated as strategic indicators, or KPIs are defined without clear ownership or accountability.

How to fix it:
Clearly distinguish between metrics and KPIs. Assign owners to each KPI and ensure they are reviewed regularly with a focus on decisions and outcomes.

Poor or Inconsistent Definitions

The mistake:
Different teams use the same terms—such as “customer,” “active user,” or “revenue”—but mean different things. This leads to conflicting numbers and erodes trust.

How to fix it:
Create and maintain shared definitions through a business glossary or semantic layer. Make definitions visible and easy to reference, not hidden in documentation no one reads.

Ignoring Data Quality Until It’s a Crisis

The mistake:
Data quality issues are only addressed after reports are wrong, decisions are challenged, or leadership loses confidence.

How to fix it:
Treat data quality as an ongoing discipline. Monitor freshness, completeness, accuracy, and consistency. Build checks into pipelines and surface issues early.

Relying Too Much on Manual Processes

The mistake:
Critical reports depend on spreadsheets, manual data pulls, or individual expertise. This creates risk, delays, and scalability issues.

How to fix it:
Automate data pipelines and reporting wherever possible. Reduce dependency on individuals and create repeatable, documented processes.

Focusing on Tools Instead of Understanding

The mistake:
Organizations invest heavily in BI tools, data platforms, or AI features but don’t invest equally in data literacy.

How to fix it:
Train users to understand data, ask better questions, and interpret results correctly. The value of data comes from people, not platforms.

Lacking Clear Ownership and Governance

The mistake:
No one is accountable for data domains, leading to duplication, inconsistency, and confusion.

How to fix it:
Define clear ownership for data domains, datasets, and KPIs. Lightweight governance—focused on clarity and accountability—often works better than rigid controls.

Using Historical Data Only

The mistake:
Decisions are based solely on past performance, with little attention to leading indicators or real-time signals.

How to fix it:
Complement historical reporting with forward-looking and operational metrics. Trends, early signals, and predictive indicators enable proactive decision-making.

Losing Sight of the Business Question

The mistake:
Teams focus on building reports and models without a clear understanding of the business problem they’re trying to solve.

How to fix it:
Start every data initiative with a simple question: What decision will this support? Let the question drive the data—not the other way around.

In Summary

Most data problems aren’t technical—they’re organizational, cultural, or conceptual. Businesses that succeed with data focus less on collecting more information and more on creating clarity, trust, and action.

Strong data practices don’t just produce insights. They enable better decisions, faster responses, and sustained business value.

Thanks for reading and good luck on your data journey!

Metrics vs KPIs: What’s the Difference?

The terms metrics and KPIs (Key Performance Indicators) are often used interchangeably, but they are not the same thing. Understanding the difference helps teams focus on what truly matters instead of tracking everything.

What Is a Metric?

A metric is any quantitative measure used to track an activity, process, or outcome. Metrics answer the question:

“What is happening?”

Examples of metrics include:

Number of website visits
Average query duration
Support tickets created per day
Data refresh success rate

Metrics are abundant and valuable. They provide visibility into operations and performance, but on their own, they don’t always indicate success or failure.

What Is a KPI?

A KPI (Key Performance Indicator) is a specific type of metric that is directly tied to a strategic business objective. KPIs answer the question:

“Are we succeeding at what matters most?”

Examples of KPIs include:

Customer retention rate
Revenue growth
On-time data availability SLA
Net Promoter Score (NPS)

A KPI is not just measured—it is monitored, discussed, and acted upon at a leadership or decision-making level.

The Key Differences

Purpose

Metrics provide insight and detail.
KPIs track progress toward critical goals.

Scope

Metrics are broad and numerous.
KPIs are few and highly focused.

Audience

Metrics are often used by analysts and operational teams.
KPIs are used by leadership and decision-makers.

Actionability

Metrics may or may not drive action.
KPIs are designed to trigger decisions and accountability.

How Metrics Support KPIs

KPIs rarely exist in isolation. They are usually supported by multiple underlying metrics. For example:

A customer retention KPI may be supported by metrics such as churn by segment, feature usage, and support response time.
A data platform reliability KPI may rely on refresh failures, latency, and incident counts.

Metrics provide the diagnostic detail; KPIs provide the direction.

Common Mistakes to Avoid

Too many KPIs: When everything is “key,” nothing is.
Unowned KPIs: Every KPI should have a clear owner responsible for outcomes.
Vanity KPIs: A KPI should drive action, not just look good in reports.
Misaligned KPIs: If a KPI doesn’t clearly map to a business goal, it shouldn’t be a KPI.

When to Use Each

Use metrics to understand, analyze, and optimize processes.
Use KPIs to evaluate success, guide priorities, and align teams around shared goals.

In Summary

All KPIs are metrics, but not all metrics are KPIs. Metrics tell the story of what’s happening across the business, while KPIs highlight the chapters that truly matter. Strong analytics practices use both—metrics for insight and KPIs for focus.

Self-Service Analytics: Empowering Users While Maintaining Trust and Control

Self-service analytics has become a cornerstone of modern data strategies. As organizations generate more data and business users demand faster insights, relying solely on centralized analytics teams creates bottlenecks. Self-service analytics shifts part of the analytical workload closer to the business—while still requiring strong foundations in data quality, governance, and enablement.

This article is based on a detailed presentation I did at a HIUG conference a few years ago.

What Is Self-Service Analytics?

Self-service analytics refers to the ability for business users—such as analysts, managers, and operational teams—to access, explore, analyze, and visualize data on their own, without requiring constant involvement from IT or centralized data teams.

Instead of submitting requests and waiting days or weeks for reports, users can:

Explore curated datasets
Build their own dashboards and reports
Answer ad-hoc questions in real time
Make data-driven decisions within their daily workflows

Self-service does not mean unmanaged or uncontrolled analytics. Successful self-service environments combine user autonomy with governed, trusted data and clear usage standards.

Why Implement or Provide Self-Service Analytics?

Organizations adopt self-service analytics to address speed, scalability, and empowerment challenges.

Key Benefits

Faster Decision-Making
Users can answer questions immediately instead of waiting in a reporting queue.
Reduced Bottlenecks for Data Teams
Central teams spend less time producing basic reports and more time on high-value work such as modeling, optimization, and advanced analytics.
Greater Business Engagement with Data
When users interact directly with data, data literacy improves and analytics becomes part of everyday decision-making.
Scalability
A small analytics team cannot serve hundreds or thousands of users manually. Self-service scales insight generation across the organization.
Better Alignment with Business Context
Business users understand their domain best and can explore data with that context in mind, uncovering insights that might otherwise be missed.

Why Not Implement Self-Service Analytics? (Challenges & Risks)

While powerful, self-service analytics introduces real risks if implemented poorly.

Common Challenges

Data Inconsistency & Conflicting Metrics
Without shared definitions, different users may calculate the same KPI differently, eroding trust.
“Spreadsheet Chaos” at Scale
Self-service without governance can recreate the same problems seen with uncontrolled Excel usage—just in dashboards.
Overloaded or Misleading Visuals
Users may build reports that look impressive but lead to incorrect conclusions due to poor data modeling or statistical misunderstandings.
Security & Privacy Risks
Improper access controls can expose sensitive or regulated data.
Low Adoption or Misuse
Without training and support, users may feel overwhelmed or misuse tools, resulting in poor outcomes.
Shadow IT
If official self-service tools are too restrictive or confusing, users may turn to unsanctioned tools and data sources.

**What an Environment Looks Like Without Self-Service Analytics**

In organizations without self-service analytics, patterns tend to repeat:

Business users submit report requests via tickets or emails
Long backlogs form for even simple questions
Analytics teams become report factories
Insights arrive too late to influence decisions
Users create their own disconnected spreadsheets and extracts
Trust in data erodes due to multiple versions of the truth

Decision-making becomes reactive, slow, and often based on partial or outdated information.

**How Things Change With Self-Service Analytics**

When implemented well, self-service analytics fundamentally changes how an organization works with data.

Users explore trusted datasets independently
Analytics teams focus on enablement, modeling, and governance
Insights are discovered earlier in the decision cycle
Collaboration improves through shared dashboards and metrics
Data becomes part of daily conversations, not just monthly reports

The organization shifts from report consumption to insight exploration. Well, that’s the goal.

How to Implement Self-Service Analytics Successfully

Self-service analytics is as much an operating model as it is a technology choice. The list below outlines important aspects that must be considered, decided on, and implemented when planning the implementation of self-service analytics.

1. Data Foundation

Curated, well-modeled datasets (often star schemas or semantic models)
Clear metric definitions and business logic
Certified or “gold” datasets for common use cases
Data freshness aligned with business needs

A strong semantic layer is critical—users should not have to interpret raw tables.

2. Processes

Defined workflows for dataset creation and certification
Clear ownership for data products and metrics
Feedback loops for users to request improvements or flag issues
Change management processes for metric updates

3. Security

Role-based access control (RBAC)
Row-level and column-level security where needed
Separation between sensitive and general-purpose datasets
Audit logging and monitoring of usage

Security must be embedded, not bolted on.

4. Users & Roles

Successful self-service environments recognize different user personas:

Consumers: View and interact with dashboards
Explorers: Build their own reports from curated data
Power Users: Create shared datasets and advanced models
Data Teams: Govern, enable, and support the ecosystem

Not everyone needs the same level of access or capability.

5. Training & Enablement

Tool-specific training (e.g., how to build reports correctly)
Data literacy education (interpreting metrics, avoiding bias)
Best practices for visualization and storytelling
Office hours, communities of practice, and internal champions

Training is ongoing—not a one-time event.

6. Documentation

Metric definitions and business glossaries
Dataset descriptions and usage guidelines
Known limitations and caveats
Examples of certified reports and dashboards

Good documentation builds trust and reduces rework.

7. Data Governance

Self-service requires guardrails, not gates.

Key governance elements include:

Data ownership and stewardship
Certification and endorsement processes
Naming conventions and standards
Quality checks and validation
Policies for personal vs shared content

Governance should enable speed while protecting consistency and trust.

8. Technology & Tools

Modern self-service analytics typically includes:

Data Platforms

Cloud data warehouses or lakehouses
Centralized semantic models

Data Visualization & BI Tools

Interactive dashboards and ad-hoc analysis
Low-code or no-code report creation
Sharing and collaboration features

Supporting Capabilities

Metadata management
Cataloging and discovery
Usage monitoring and adoption analytics

The key is selecting tools that balance ease of use with enterprise-grade governance.

Conclusion

Self-service analytics is not about giving everyone raw data and hoping for the best. It is about empowering users with trusted, governed, and well-designed data experiences.

Organizations that succeed treat self-service analytics as a partnership between data teams and the business—combining strong foundations, thoughtful governance, and continuous enablement. When done right, self-service analytics accelerates decision-making, scales insight creation, and embeds data into the fabric of everyday work.

Data Conversions: Steps, Best Practices, and Considerations for Success

Introduction

Data conversions are critical undertakings in the world of IT and business, often required during system upgrades, migrations, mergers, or to meet new regulatory requirements. I have been involved in many data conversions over the years, and in this article, I am sharing information from that experience. This article provides a comprehensive guide to the stages, steps, and best practices for executing successful data conversions. This article was created from a detailed presentation I did some time back at a SQL Saturday event.

What Is Data Conversion and Why Is It Needed?

Data conversion involves transforming data from one format, system, or structure to another. Common scenarios include application upgrades, migrating to new systems, adapting to new business or regulatory requirements, and integrating data after mergers or acquisitions. For example, merging two customer databases into a new structure is a typical conversion challenge.

Stages of a Data Conversion Project

Let’s take a look at the stages of a data conversion project.

Stage 1: Big Picture, Analysis, and Feasibility

The first stage is about understanding the overall impact and feasibility of the conversion:

Understand the Big Picture: Identify what the conversion is about, which systems are involved, the reasons for conversion, and its importance. Assess the size, complexity, and impact on business and system processes, users, and external parties. Determine dependencies and whether the conversion can be done in phases.
Know Your Sources and Destinations: Profile the source data, understand its use, and identify key measurements for success. Compare source and destination systems, noting differences and existing data in the destination.
Feasibility – Proof of Concept: Test with the most critical or complex data to ensure the conversion will meet the new system’s needs before proceeding further.
Project Planning: Draft a high-level project plan and requirements document, estimate complexity and resources, assemble the team, and officially launch the project.

Stage 2: Impact, Mappings, and QA Planning

Once the conversion is likely, the focus shifts to detailed impact analysis and mapping:

Impact Analysis: Assess how business and system processes, reports, and users will be affected. Consider equipment and resource needs, and make a go/no-go decision.
Source/Destination Mapping & Data Gap Analysis: Profile the data, create detailed mappings, list included and excluded data, and address gaps where source or destination fields don’t align. Maintain legacy keys for backward compatibility.
QA/Verification Planning: Plan for thorough testing, comparing aggregates and detailed records between source and destination, and involve both IT and business teams in verification.

Stage 3: Project Execution, Development, and QA

With the project moving forward, detailed planning, development and validation, and user involvement become the priority:

Detailed Project Planning: Refine requirements, assign tasks, and ensure all parties are aligned. Communication is key.
Development: Set up environments, develop conversion scripts and programs, determine order of processing, build in logging, and ensure processes can be restarted if interrupted. Optimize for performance and parallel processing where possible.
Testing and Verification: Test repeatedly, verify data integrity and functionality, and involve all relevant teams. Business users should provide final sign-off.
Other Considerations: Train users, run old and new systems in parallel, set a firm cut-off for source updates, consider archiving, determine if any SLAs needed to be adjusted, and ensure compliance with regulations.

Stage 4: Execution and Post-Conversion Tasks

The final stage is about production execution and transition:

Schedule and Execute: Stick to the schedule, monitor progress, keep stakeholders informed, lock out users where necessary, and back up data before running conversion processes.
Post-Conversion: Run post-conversion scripts, allow limited access for verification, and where applicable, provide close monitoring and support as the new system goes live.

Best Practices and Lessons Learned

Involve All Stakeholders Early: Early engagement ensures smoother execution and better outcomes.
Analyze and Plan Thoroughly: A well-thought-out plan is the foundation of a successful conversion.
Develop Smartly and Test Vigorously: Build robust, traceable processes and test extensively.
Communicate Throughout: Keep all team members and stakeholders informed at every stage.
Pay Attention to Details: Watch out for tricky data types like DATETIME and time zones, and never underestimate the effort required.

Conclusion

Data conversions are complex, multi-stage projects that require careful planning, execution, and communication. By following the structured approach and best practices outlined above, organizations can minimize risks and ensure successful outcomes.

Configure a Semantic Model Scheduled Refresh (PL-300 Exam Prep)

This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Manage and secure Power BI (15–20%)
   --> Create and manage workspaces and assets
      --> Configure a Semantic Model Scheduled Refresh

Note that there are 10 practice questions (with answers and explanations) at the end of each topic. Also, there are 2 practice tests with 60 questions each available on the hub below all the exam topics.

Overview

A semantic model scheduled refresh ensures that Power BI reports and dashboards display up-to-date data without requiring manual intervention. For the PL-300 exam, this topic focuses on understanding when scheduled refresh is supported, what prerequisites are required, and how to configure refresh settings correctly in the Power BI service.

This skill sits at the intersection of data connectivity, security, and workspace management.

What Is a Semantic Model Scheduled Refresh?

A scheduled refresh automatically reimports data into a Power BI semantic model (dataset) at defined times using the Power BI service. It applies only to Import mode and composite models with imported tables.

Scheduled refresh does not apply to:

DirectQuery-only models
Live connections to Power BI or Analysis Services

Prerequisites for Scheduled Refresh

Before configuring scheduled refresh, the following conditions must be met:

1. Dataset Must Be Published

Scheduled refresh can only be configured after publishing the semantic model to the Power BI service.

2. Valid Data Source Credentials

You must provide and maintain valid credentials for all data sources used in the dataset.

Supported authentication methods vary by source and may include:

OAuth
Basic authentication
Windows authentication
Organizational account

3. Gateway (If Required)

A gateway is required when the semantic model connects to:

On-premises data sources
Data sources in a private network
On-premises dataflows

Cloud-based sources (such as Azure SQL Database or SharePoint Online) do not require a gateway.

4. Import Mode Tables

At least one table in the semantic model must use Import mode. DirectQuery-only models do not support scheduled refresh.

Configuring Scheduled Refresh

Scheduled refresh is configured in the Power BI service, not in Power BI Desktop.

Key Configuration Steps

Navigate to the workspace
Select the semantic model
Open Settings
Configure:
- Data source credentials
- Gateway connection (if applicable)
- Refresh schedule

Refresh Frequency and Limits

Shared Capacity

Up to 8 refreshes per day
Minimum interval of 30 minutes

Premium Capacity

Up to 48 refreshes per day
Shorter refresh intervals supported

These limits are enforced per dataset.

Refresh Options and Settings

Scheduled Refresh

Allows you to define:

Days of the week
Time slots
Time zone
Enable/disable refresh

Refresh Failure Notifications

You can configure email notifications to alert dataset owners if a refresh fails.

Incremental Refresh

Incremental refresh:

Requires Power BI Desktop configuration
Reduces refresh time by refreshing only new or changed data
Still depends on scheduled refresh to execute

Common Causes of Refresh Failure

Expired credentials
Gateway offline or misconfigured
Data source schema changes
Timeout due to large datasets
Unsupported data source authentication

Scenarios Where Scheduled Refresh Is Not Needed

DirectQuery datasets (data is queried live)
Live connections to Analysis Services
Manual refresh and republish workflows (not recommended for production)

Exam-Focused Decision Rules

For the PL-300 exam, remember:

Import mode = scheduled refresh
DirectQuery = no scheduled refresh
On-premises source = gateway required
Refresh settings live in the Power BI service
Premium capacity allows more frequent refreshes

Common Exam Traps

Confusing scheduled refresh with DirectQuery
Assuming all datasets require a gateway
Forgetting credential configuration
Thinking refresh schedules are set in Desktop

Key Takeaways

Scheduled refresh keeps semantic models current
Configuration happens in the Power BI service
Gateways depend on data source location
Capacity affects refresh frequency
Incremental refresh improves performance but still relies on scheduling
