Power BI is a visualisation and Business Intelligence (BI) tool from Microsoft, aimed at helping turn data into insights.
Power BI allows you to stitch together data from across your organisation and create beautiful reports and dashboards.
You can connect hundreds of data sources in Power BI, including many competitor services to Microsoft.
The Components of Power BI
There are 3 main components of Power BI:
Power BI Desktop
Power BI Desktop is a Windows application that allows you to build reports, dashboards and analyse data.
Power BI Services
Power BI Services is a cloud-based Software as a Service (SaaS) application. It extends the reporting that is created by adding secured sharing (dynamic row-level security), refreshes, and various other functionality.
Power BI Mobile
Power BI Mobile allows you to view any of your reporting through your phone.
Comparing Power BI vs Excel
There are a great many similarities between Power BI and Excel.
Excel is a great tool for doing calculations and things like budgets.
Excel can do some basic reporting with pivot tables and charts but is not designed for reporting.
Reporting is where Power BI comes into its own.
Not only can you create beautiful visualisations (see this article for customising your Power BI themes), but the user interface allows users to interact with the data with things like the tree decomposition visual. This enables users to draw many more insights from the data.
Power BI is also much more robust for building reports and dashboards than Excel.
For a more detailed description of the differences between Power BI and Excel, you can look here.
Competitors To Power BI
Power BI has many competitors offering reporting and BI tools. Each has its own pros and cons.
Below is Gartner’s Magic Quadrant report that they produce every year, showcasing in their view the leaders in the Analytics and Business Intelligence space.
Practical Use Cases For Power BI
There are many great use cases for Power BI that cover different industries and roles, let’s walk through a few of them.
Scenario 1: An Organisation That Uses Excel For Reporting
One scenario is you work in an organisation that has historically done all of your reporting in Excel.
Your reports are manually generated or updated and emailed around each day, week or month. This is a very typical situation.
Power BI is great in this situation. In fairly short order, you will be able to connect the variety of spreadsheets, as well as other data sources and to create reports and dashboards.
Power BI will also ensure that confidential data is far more secure and confidential than simply emailing spreadsheets.
Scenario 2: An Organisation With Lots Of Reporting Tools
Another common scenario is an organisation that uses a number of different reporting tools. This can happen when a mix of IT systems are implemented, all with their own built-in reporting tool.
The challenge is that you have to go into each system to view reports in isolation, or worse, export the data and create a summary report.
The biggest benefit here is being able to schedule the refresh of your data loads without having to export or import data, although manually exporting to PowerPoint and other Office applications is very simple, as you’d expect from a Microsoft product.
The value of Power BI is not just for people analysing data, it is for every decision-maker as well.
Imagine having a link to your own report or dashboard that has been curated from many different data sources.
It not only contains the information that is relevant to you, but is also refreshed daily (or potentially more often), easy to navigate and is simple for you to explain and share with others.
Enabling others to explore data in a simple way is one of the first steps to becoming a data-driven organisation.
Scenario 3: Getting Started With Power BI
Power BI is also a great tool for anyone or any business trying to learn business intelligence and analytics.
Since it is a free tool (initially), anyone with access to a Windows computer can run it. With its similar feel to Excel, users that currently create reports in Excel will have an easier time picking up Power BI and very sooner be doing things like combining and merging data using merge queries or manipulating difficult date formats.
However, Power BI comes with a number of different licences. As you subscribe to more powerful Power BI licences, it allows you to do more with your data. This means that Power BI can very easily adapt with an organisation as it develops its business intelligence capabilities.
In its most advanced offering Power BI offers automated machine learning capabilities.
Different Components of Power BI
For anyone new to Power BI, there will likely be some unfamiliar terminology:
- Power Query: A tool used to transform your data and prep it to be used in reporting
- DAX: Stands for Data Analysis Expressions, and it is the language you write formulas in.
- Measures: Similar to calculated fields in Excel, they allow for dynamic results based on how you interact with the report.
- Interactions: The ability to click on, drill into and slice reports to uncover additional insights.
- Slicer: The equivalent to a filter.
- Data Model: The ability to transform your data, connect it with other datasets and build relationships between your data.
- Power Query: For data processing & management
- Power Pivot: For data modelling & calculations
- Power BI Visuals: For data visualisation and interactions (for example the Q&A visual, or the smart narrative visual)
