From Raw Data to Better Decisions

Data analytics is not simply the process of creating charts.

Professional analytics begins with understanding the problem that needs to be solved and ends when data leads to an informed decision or measurable action.

The IBACTP® Data Analytics Guides provide practical resources across the complete analytical lifecycle.

THE DATA ANALYTICS LIFECYCLE

Step 1 DEFINE THE QUESTION Read this step

Good analysis begins with a good question.

Before opening a spreadsheet, database, notebook, or dashboard platform, analysts should determine:

What decision needs to be made?

What business problem are we attempting to solve?

Who will use the analysis?

What information do decision-makers need?

What outcome should the analysis influence?

What data is available?

What constraints exist?

How will success be measured?

Weak questions produce weak analytics.

Instead of asking:

“What does the data say?”

Professional analysts ask:

“What decision are we trying to improve, and what evidence is needed to make that decision?”

Step 2 IDENTIFY & COLLECT DATA Read this step

Analytical data may come from:

• Transaction systems
• CRM platforms
• ERP systems
• HR systems
• Financial systems
• Websites
• Mobile applications
• IoT devices
• Sensors
• APIs
• Surveys
• Social platforms
• Cloud applications
• Data warehouses
• Data lakes
• Government datasets
• Research repositories
• Third-party providers

Before using data, professionals should evaluate:

Relevance

Does the data answer the question?

Accuracy

Can the information be trusted?

Completeness

Are important records or variables missing?

Timeliness

Is the data current enough for the decision?

Consistency

Are definitions and formats aligned?

Legality & Ethics

Is the organization authorized to collect and use the information?

Step 3 PREPARE & CLEAN THE DATA Read this step

Most Analytics Work Begins Before Analysis

Poor-quality data can produce misleading conclusions regardless of how sophisticated the analytical technique may be.

Data preparation can include:

• Removing duplicates
• Managing missing values
• Identifying outliers
• Correcting inconsistent formats
• Standardizing categories
• Converting data types
• Combining data sources
• Reshaping tables
• Validating records
• Creating calculated fields
• Handling invalid values
• Detecting data-entry problems

The Objective

Transform raw information into a dataset that is:

• Accurate
• Consistent
• Complete enough
• Relevant
• Structured
• Analysis-ready

Step 4 EXPLORE THE DATA Read this step

Understand Before You Model

Exploratory Data Analysis helps analysts understand patterns, distributions, relationships, anomalies, and potential data-quality issues before formal modeling begins.

Common techniques include:

• Summary statistics
• Frequency distributions
• Histograms
• Box plots
• Scatter plots
• Correlation analysis
• Cross-tabulation
• Trend analysis
• Segmentation
• Outlier analysis

Professionals should ask:

What does a typical observation look like?

Which variables vary significantly?

Are there unusual values?

Which variables appear related?

Are there important differences among groups?

Does the data contain seasonal or time-based patterns?

Step 5 ANALYZE Read this step

Different questions require different analytical methods.

Descriptive Analytics

What happened?

Examples:

• Monthly revenue
• Employee turnover
• Website traffic
• Customer complaints
• Security incidents
• Inventory levels

Diagnostic Analytics

Why did it happen?

Examples:

Why did sales decline?

Why did customer churn increase?

Why did a project exceed budget?

Why did network availability decrease?

Predictive Analytics

What is likely to happen?

Examples:

• Demand forecasting
• Customer churn prediction
• Fraud detection
• Equipment failure prediction
• Credit-risk modeling

Prescriptive Analytics

What should we do?

Examples:

• Inventory optimization
• Route optimization
• Workforce scheduling
• Pricing recommendations
• Resource allocation

Step 6 VISUALIZE Read this step

Visualization transforms analytical results into forms people can understand.

Common visualizations include:

• Bar charts
• Line charts
• Scatter plots
• Histograms
• Heat maps
• Maps
• Treemaps
• Waterfall charts
• KPI cards
• Dashboards

The best visualization is not necessarily the most visually impressive.

It is the visualization that communicates the insight quickly, accurately, and without distortion.

Step 7 INTERPRET Read this step

Analytics requires professional judgment.

Analysts should distinguish among:

Correlation

Variables move together.

Causation

One factor contributes to another.

Association

A relationship is observed without establishing cause.

Statistical Significance

A result may be unlikely to have occurred by chance.

Practical Significance

The result is important enough to influence a real-world decision.

Step 8 COMMUNICATE Read this step

Analytics Must Be Understood to Create Value

Analysts increasingly need the ability to communicate with:

• Executives
• Managers
• Technical teams
• Customers
• Regulators
• Auditors
• Business stakeholders

Effective analytical communication should explain:

• What happened?
• Why does it matter?
• What evidence supports the conclusion?
• What should be done next?
• 9. ACT

Analysis should lead to a decision, intervention, experiment, or operational action.

Step 10 MEASURE Full detail

Determine whether the action produced the intended result.

This creates a continuous analytics cycle:

• QUESTION
• DATA
• ANALYSIS
• INSIGHT
• DECISION
• ACTION
• MEASUREMENT
• IMPROVEMENT

ESSENTIAL ANALYTICS SKILLS

Modern analysts should develop competency across several areas.

Data Literacy
