Perform impact analysis of downstream dependencies from lakehouses, data warehouses, dataflows, and semantic models in Microsoft Fabric

 
This post is a part of the DP-600: Implementing Analytics Solutions Using Microsoft Fabric Exam Prep Hub; and this topic falls under these sections: 
Maintain a data analytics solution 
    --> Maintain the analytics development lifecycle 
        --> Perform impact analysis of downstream dependencies from lakehouses, 
            data warehouses, dataflows, and semantic models

Impact analysis in Microsoft Fabric helps analytics engineers understand how changes to upstream data assets affect downstream items such as datasets, reports, dashboards, notebooks, and pipelines. It is a critical lifecycle practice that reduces the risk of breaking analytics solutions when making schema, logic, or data changes.

For the DP-600 exam, you should understand what impact analysis is, which Fabric tools support it, what dependencies are tracked, and how to use it in real-world lifecycle scenarios.

What Is Impact Analysis?

Impact analysis answers the question:

“If I change or delete this item, what else will be affected?”

It allows you to:

  • Identify downstream dependencies
  • Assess risk before making changes
  • Communicate potential impacts to stakeholders
  • Support safe development and deployment practices

Impact analysis is observational and informational—it does not enforce controls.

Where Impact Analysis Is Used in Fabric

Impact analysis applies across many Fabric items, including:

  • Lakehouses
  • Data Warehouses
  • Dataflows Gen2
  • Semantic models
  • Reports and dashboards
  • Notebooks and pipelines

These items form a connected analytics graph, which Fabric can visualize.

Lineage View: The Core Tool for Impact Analysis

The primary tool for impact analysis in Fabric is Lineage View.

What Lineage View Shows

  • Upstream data sources
  • Transformations and processing steps
  • Downstream consumers
  • Relationships between items

Lineage view provides a visual map of dependencies across workloads.

Impact Analysis by Asset Type

Lakehouses

Changing a Lakehouse can impact:

  • Notebooks reading tables
  • Semantic models using Direct Lake
  • Dataflows writing or reading data
  • Reports built on dependent models

Common risk: Dropping or renaming a column.

Data Warehouses

Warehouse changes may affect:

  • Views and SQL queries
  • Semantic models using DirectQuery
  • Reports and dashboards
  • External tools

Exam insight: Schema changes are a common source of downstream failures.

Dataflows Gen2

Dataflows often sit between raw data and analytics.

Changes can impact:

  • Lakehouses or Warehouses they load into
  • Semantic models consuming curated tables
  • Pipelines orchestrating refreshes

Semantic Models

Semantic models are among the most sensitive assets.

Changes may affect:

  • Reports and dashboards
  • Excel workbooks
  • Composite models
  • End-user self-service analytics

Exam note: Removing measures or renaming fields is high risk.

How to Perform Impact Analysis (High Level)

  1. Select the item (Lakehouse, Warehouse, Dataflow, or Semantic Model)
  2. Open Lineage view
  3. Review downstream dependencies
  4. Identify:
    • Reports
    • Datasets
    • Pipelines
    • Other dependent items
  5. Communicate or mitigate risk before making changes

Impact Analysis in the Development Lifecycle

Impact analysis is typically performed:

  • Before deploying changes
  • Before modifying schemas
  • Before deleting items
  • During troubleshooting

It supports:

  • Safe Git commits
  • Controlled pipeline deployments
  • Production stability

Common Exam Scenarios

You may see questions such as:

  • A column change breaks multiple reports → impact analysis was skipped
  • An engineer needs to know which reports use a dataset → lineage view
  • A Lakehouse schema update affects downstream models → review dependencies
  • A dataset should not be modified due to executive reports → high downstream impact

Example:

Before removing a table from a semantic model, what should you do?
Correct concept: Perform impact analysis using lineage view.

Impact Analysis vs Deployment Pipelines

These concepts are related but distinct.

Best Practices to Remember

  • Always check lineage before schema changes
  • Pay extra attention to semantic models and certified items
  • Communicate impacts to report owners
  • Pair impact analysis with:
    • Version control
    • Development pipelines
    • Endorsements and certification

Key Exam Takeaways

  • Impact analysis identifies downstream dependencies
  • Lineage view is the primary tool in Fabric
  • Applies to Lakehouses, Warehouses, Dataflows, and Semantic Models
  • Supports safe lifecycle and governance practices
  • A common scenario-based exam topic

Final Exam Tip

  • If a question asks what will break if I change this, the answer is impact analysis via lineage view.
  • If it asks how to safely move changes, the answer is pipelines or Git.
  • Expect questions that test:
    • When to perform impact analysis
    • Which items are affected by changes
    • Operational decision-making before deployments
  • Common traps:
    • Confusing impact analysis with lineage documentation
    • Assuming Fabric blocks breaking changes automatically
    • Forgetting semantic models are often the most impacted layer

Create and Update Reusable Assets, including Power BI template (.pbit) files, Power BI data source (.pbids) files, and shared semantic models in Microsoft Fabric

 
This post is a part of the DP-600: Implementing Analytics Solutions Using Microsoft Fabric Exam Prep Hub; and this topic falls under these sections: 
Maintain a data analytics solution 
    --> Maintain the analytics development lifecycle 
        --> Create and update reusable assets, including Power BI template (.pbit) 
            files, Power BI data source (.pbids) files, and shared semantic models

Reusable assets are a key lifecycle concept in Microsoft Fabric and Power BI. They enable consistency, scalability, and efficiency by allowing teams to standardize how data is connected, modeled, and visualized across multiple solutions.

For the DP-600 exam, you should understand what reusable assets are, how to create and manage them, and when each type is appropriate.

What Are Reusable Assets?

Reusable assets are analytics artifacts designed to be:

  • Used by multiple users or teams
  • Reapplied across projects
  • Centrally governed and maintained

Common reusable assets include:

  • Power BI template (.pbit) files
  • Power BI data source (.pbids) files
  • Shared semantic models

Power BI Template Files (.pbit)

What Is a PBIT File?

A .pbit file is a Power BI template that contains:

  • Report layout and visuals
  • Data model structure (tables, relationships, measures)
  • Parameters and queries (without data)

It does not include actual data.

When to Use PBIT Files

PBIT files are ideal when:

  • Standardizing report design and metrics
  • Distributing reusable report frameworks
  • Supporting self-service analytics at scale
  • Onboarding new analysts

Creating and Updating PBIT Files

  • Create a report in Power BI Desktop
  • Remove data (if present)
  • Save as Power BI Template (.pbit)
  • Store in source control or shared repository
  • Update centrally and redistribute as needed

Power BI Data Source Files (.pbids)

What Is a PBIDS File?

A .pbids file is a JSON-based file that defines:

  • Data source connection details
  • Server, database, or endpoint information
  • Authentication type (but not credentials)

Opening a PBIDS file launches Power BI Desktop and guides users through connecting to the correct data source.

When to Use PBIDS Files

PBIDS files are useful for:

  • Standardizing data connections
  • Reducing configuration errors
  • Guiding business users to approved sources
  • Supporting governed self-service analytics

Managing PBIDS Files

  • Create manually or export from Power BI Desktop
  • Store centrally (e.g., Git, SharePoint)
  • Update when connection details change
  • Pair with shared semantic models where possible

Shared Semantic Models

What Are Shared Semantic Models?

Shared semantic models are centrally managed datasets that:

  • Define business logic, measures, and relationships
  • Serve as a single source of truth
  • Are reused across multiple reports

They are one of the most important reusable assets in Fabric.

Benefits of Shared Semantic Models

  • Consistent metrics across reports
  • Reduced duplication
  • Centralized governance
  • Better performance and manageability

Managing Shared Semantic Models

Shared semantic models are:

  • Developed by analytics engineers
  • Published to Fabric workspaces
  • Shared using Build permission
  • Governed with:
    • RLS and OLS
    • Sensitivity labels
    • Endorsements (Promoted/Certified)

How These Assets Work Together

A common pattern:

  • PBIDS → Standardizes connection
  • Shared semantic model → Defines logic
  • PBIT → Standardizes report layout

This layered approach is frequently tested in exam scenarios.

Reusable Assets and the Development Lifecycle

Reusable assets support:

  • Faster development
  • Consistent deployments
  • Easier maintenance
  • Scalable self-service analytics

They align naturally with:

  • PBIP projects
  • Git version control
  • Development pipelines
  • XMLA-based automation

Common Exam Scenarios

You may be asked:

  • How to distribute a standardized report template → PBIT
  • How to ensure users connect to the correct data source → PBIDS
  • How to enforce consistent business logic → Shared semantic model
  • How to reduce duplicate datasets → Shared model + Build permission

Example:

Multiple teams need to create reports using the same metrics and layout.
Correct concepts: Shared semantic model and PBIT.

Best Practices to Remember

  • Centralize ownership of shared semantic models
  • Certify trusted reusable assets
  • Store templates and PBIDS files in source control
  • Avoid duplicating business logic in individual reports
  • Pair reusable assets with governance features

Key Exam Takeaways

  • Reusable assets improve consistency and scalability
  • PBIT files standardize report design
  • PBIDS files standardize data connections
  • Shared semantic models centralize business logic
  • All are core lifecycle tools in Fabric

Exam Tips

  • If a question focuses on standardization, reuse, or self-service at scale, think PBIT, PBIDS, and shared semantic models—and choose the one that matches the problem being solved.
  • Expect scenarios that test:
    • When to use PBIT vs PBIDS vs shared semantic models
    • Governance and consistency
    • Enterprise BI scalability
  • Quick memory aid:
    • PBIT = Layout + Model (no data)

Analytics, Business Intelligence, Data Analysis, Data Strategy

Developing metrics for your analytics project

When starting an analytics project, one of the most important decisions you will make is identifying the right metrics. Metrics serve as the compass for the initiative—they show whether you are on the right track, communicate achievements, highlight challenges, uncover blind spots, and ultimately, along with guiding future decisions, they demonstrate the value of the project to stakeholders. But designing metrics is not as simple as picking a single “success number.” To truly guide decision-making, you need a holistic set of measures that reflect multiple dimensions of performance.

Why a Holistic View Matters

Analytics projects sometimes fall into the trap of focusing on only one type of metric. For example, a project might track quantity (e.g., number of leads generated) while ignoring quality (e.g., lead conversion rate). Or it may measure cost savings but fail to consider user satisfaction, leading to short-term wins but long-term disengagement.

Develop Metrics from Multiple Dimensions

To avoid this pitfall, it’s critical to develop a balanced framework that includes multiple perspectives:

  • Quantity: How much output is produced? Examples include number of units produced, sales revenue, or number of new customers added.
  • Quality: What is the quality of the output? Examples include accuracy rates, defect counts, or error percentages.
  • Time: How long does it take to achieve the output? Or in other words, what timeframe is the quantity and quality measured over? Is it Sales revenue per hour, per day, per month, or per year?
  • Costs: What resources are being consumed? Metrics might include infrastructure costs, labor hours and costs, materials costs, or overall project spend.
  • Satisfaction: How do stakeholders, customers, or employees feel about the results? Feedback surveys, adoption rates, product ratings, and net promoter scores (NPS) are common ways of identifying this information.

Each of these perspectives contributes to the full story of your analytics project. If one dimension is missing, you risk optimizing for one outcome at the expense of another.

Efficiency, Effectiveness, and Impact Metrics

Another way you can classify your metrics to achieve a holistic view is with three overarching categories: Efficiency, Effectiveness, and Impact.

  • Efficiency Metrics
    • These measure how well resources are used and answers “are we doing things right?“. They focus on inputs versus outputs.
      • Example: “Average work hours per product” shows how quickly work gets done.
      • Example: “Cost per customer acquired” reflects the efficiency of your sales operations.
    • Efficiency metrics often tie directly to quantity, cost, and time.
  • Effectiveness Metrics
    • These measure how well goals are achieved—whether the project delivers the intended results, and answers “are we doing the right things?“.
      • Example: “Customer satisfaction” demonstrates how happy customers are with our products and services.
      • Example: “Actual to Target” shows how things are tracking compared to the goals that were set.
    • Effectiveness metrics often involve quality, satisfaction, and time.
  • Impact Metrics
    • These measure the broader business or organizational outcomes influenced by some activity.
      • Example: “Market share and revenue growth” shows financial state from a broader market and overall standpoint.
      • Example: “Return on Investment (ROI)” is the ultimate metrics for financial performance.
    • Impact metrics communicates how we are doing with our long-term, strategic goals. They often combine quantity, quality, satisfaction, and time dimensions.

The Significance of the Time Dimension

Among all the dimensions used in metrics, time is especially powerful because it adds critical context to nearly every metric. Without time, numbers can be misleading. Just about all metrics are more relevant when the time component is added. Time transforms static measures into dynamic insights. For instance:

  • A quantity metric of “100 new customers” becomes far more meaningful when paired with “this month” versus “since company founding.”
  • A quality metric of “95% data accuracy” is less impressive if it takes weeks to achieve, compared to real-time cleansing.
  • A cost metric of “$100,000 project spend” raises different questions depending on whether it’s a one-time investment or a recurring monthly expense.

By always asking, “Over what time frame?”, you unlock a truer understanding of performance. In short, the time dimension transforms static measures into dynamic insights. It allows you to answer not just “What happened?” but also “When did it happen?”, “How long did it take?”, and “How is it changing over time?”—questions that are generally crucial for actionable decision-making.

Time adds context to every other metric. Think of it as the axis that brings your measures to life. Quantity without time tells you how much, but not how fast. Quality without time shows accuracy, but not whether results are timely enough to act upon. Costs without time hide the pace at which expenses accumulate. And satisfaction without time misses whether perceptions improve, decline, or stay consistent over an initiative’s lifecycle.

The Significance of the Timeliness

Another important consideration is timeliness. Metrics must be accessible to decision makers in a timely manner to allow them to make timely decisions. For example:

  • A metric may deliver accurate insights, but if it takes three weeks to refresh the data and the dashboard that displays it, the value erodes.
  • A machine learning model may predict outcomes with high accuracy, but if the scoring process delays operational decisions, the benefit diminishes.

Therefore, in addition to deciding on and building the metrics for a project, the delivery mechanism of the metrics (such as a dashboard) must also be thought out to ensure that the entire process, from data sourcing to aggregations to dashboard refresh for example, can all happen in a timely manner to, in turn, make the metrics available to users in a timely manner.

Putting It All Together

When developing metrics for your analytics project, take a step back and ensure you have a comprehensive, multi-angle approach, by asking:

  • Do we know how much is being achieved/produced (quantity)?
  • Do we know how well it is being achieved/produced (quality)?
  • Do we know how fast results are being delivered (time)?
  • Do we know how much it costs to achieve (costs)?
  • Do we know how it feels to those affected (satisfaction)?
  • Do we know whether we are efficiently using resources?
  • Do we know whether we are effective in reaching goals?
  • Do we know what impact this work is having on the organization?
  • And for the above questions, always get a perspective on time … when? over what timeframe?
  • When are updates to the metrics needed by (real-time, hourly, daily, weekly, monthly, etc.)?

By building metrics across these dimensions, you create a more reliable, meaningful, and balanced framework for measuring success. More importantly, you ensure that the analytics project supports not only the immediate technical objectives but also the broader organizational goals.

What is HR / People / Workforce Analytics?

An organization’s most important resource is its staff. Understanding how to take the best care of your staff and help them to be highly engaged and productive is key to the success of the organization. HR Analytics / People Analytics / Workforce Analytics can help with this. But what is that exactly?

Analytics is a multi-disciplinary field that involves the collection and curation of data, and the analysis of that data using a variety of methods and tools, to discover, interpret and share information and insights, to help develop better business understanding and help guide decision making, usually toward achieving an organization’s goals. HR / People / Workforce Analytics is analytics around an organization’s candidates and staff, and HR actions and operations. The term most commonly used for this area of specialization by people in the field has shifted from HR Analytics to People Analytics over the years, and is now trending toward Workforce Analytics, so I will just use Workforce Analytics for the rest of the article.

The data used for Workforce Analytics will come from many sources inside and outside the organization including, but not limited to, Human Capital ERP systems, Workforce applications, Recruiting applications, Payroll applications, scheduling applications, employee and candidate surveys, social media, Glassdoor, and more. This data can be transformed, integrated and aggregated as appropriate, and then analyzed to provide information to help with operational and strategic decision making around areas such as staffing, recruiting, retention, turnover, absence, compensation and benefits, employee engagement, job satisfaction, performance and productivity, training and development, diversity, equity and inclusion, and operational efficiency, among others.

This analysis is usually performed across time periods (months, years) to allow for period-to-period comparisons and trend analysis to determine if the various metrics being measured and analyzed are improving or not. And the analysis is also usually done across all levels of the organization, so that information is available to support decision making for the entire organization or for a single department or for a specific segment of employees (such as all the clinical employees within a healthcare organization) or potentially for an individual employee.

The end goal usually includes helping with efforts such as:

  • Understanding the current workforce landscape and knowing any operational tasks that need to be performed
  • Hiring better candidates by predicting candidate success and reducing recruiting/hiring costs
  • Improve employee engagement through a better understanding of employee’s true needs, and what is working and what is not, and reducing absences as a result
  • Increase employee productivity through a better understanding of how employees work and things that slow them down
  • Reducing turnover by predicting employees at a high risk of turnover and implementing proactive retention measures
  • Forecast future staffing needs to better prepare for it with recruiting and training & development
  • Determining the business impact of HR initiatives

The diagram below summarizes the Workforce Analytics components to give you an overview of this article in a quick glance.

Of course, all organizations are different, and so the goals of an organization, the type of data available and the type of analyses of interest to an organization, will vary. But the importance and value of Workforce Analytics, which helps organizations make the most of their most important resource, is critical to just about all medium to large organizations, regardless of industry and prior success.

Good luck on your analytics journey!

The 5th type of analytics – cognitive analytics

Sometime ago, I wrote an article titled “What is data analytics? And what are the different types of data analytics?”. In that post, I described four types of analytics:

  • Descriptive Analytics – what has happened?
  • Diagnostic Analytics – why something happened?
  • Predictive Analytics – what may happen (in the future)?
  • Prescriptive Analytics – what to do to make something happen?

You can read that full article here.

New capabilities and solutions have led to a new classification of analytics called Cognitive Analytics.

Cognitive Analytics involves bringing together technologies such as Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning to apply human-like behavior to data tasks at unhuman scale, such as, searching through massive amounts of data and making sense of its contexts and be able to provide information from it, such as a likely answer or a sentiment score. This form of analytics provides new solutions that do not fit into any of the other four classifications and, in short, can be dubbed as “what is found or derived“.

There are many use cases that could benefit from this type of analytics, such as, personalization of services at scale, and improved customer service efficiency.
