What is a Collab365 Challenge?

Blue Certified Solution

In many cases, our Challenges are built so that you can "learn by doing". To achieve this we follow our B.L.U.E. Framework. Learn why BLUE is a superior way to learn. Here's a summary of the 4 phases.

step 1


Learners conceptualise and start creating the app during the ‘Build It’ phase. They tap into the Power Platform’s capabilities to design an intuitive and user-friendly interface while meeting the task’s business requirements. This hands-on experience, right from the start, deepens their understanding of the platform and its functionalities.

step 2


As they move into the ‘Learn It’ stage, learners realise the platform’s intricacies, discovering functionalities they were previously unaware of. This phase provides an immediate feedback loop, allowing learners to correct misconceptions, deepen their understanding, and improve their skills.

step 3


In the ‘Use It’ phase, learners experience their creations from a user’s perspective. They test the app, identifying any flaws or usability issues. This hands-on testing and usage phase provides invaluable insights into user experience, an essential aspect of any app development process.

step 4


Finally, during the ‘Enhance It’ stage, learners refine their app based on the feedback and insights gained during testing. This iterative process simulates a real-world development cycle, reinforcing the importance of continual learning and improvement in the technology industry.

"Now I get to show off my skills at work!"

I needed to understand Power Apps formulas and have an idea of the why's and order. The coach explained it clearly and put it in terms that made it easy to understand and now I get to show off my skills at work. Not only that, if asked I can explain why I did something instead of saying, "This is what I found online and this should work.", without being able to explain the why it would work.

The pace of the course was great. I was able to complete it between leaving work and before my next call.

The detailed explanations and the short challenges along the way for me to try first before being shown how to successfully complete were fantastic. It was a moment to show that I understood and was comfortable enough with what I had learned.

Earn an industry-recognised certification.

What do I need to take the challenge?

No Previous skills necessary

We've built the Challenge for anyone to follow along with, so you don't need any previous skills. Knowing a bit about Excel or being a bit 'technically minded' is really helpful but we'll give you what you need along the way.

A Windows PC or Virtual Machine

To follow along with this Challenge, you will need a Windows PC or a virtual machine running Windows. This is because Power BI Desktop won't install on a Mac or Linux machine. 

Access To Power BI Desktop

To get the most out of the Challenge, you'll want to practice using Power BI Desktop. You can do this either by joining the Microsoft 365 Developer Program, giving you access to all the Microsoft 365 services . Or, you can use your own Microsoft 365 Tenant.
