Don’t keep it to yourself - openness and honesty in the workplace

You must have sat in a meeting, listening to someone talk about the next great innovation and how it will revolutionise the way things are done. They’ve discovered the idea, approach, or improvement, that will take the business to the next level and they’re enthusiastically extolling its virtues. However, you’ve seen the flaw in their plan … and you said nothing. You sat there silently, letting them carry on and didn’t make a sound. Why?

There are many reasons why we don’t speak up in situations like this and we'll look at why we don't speak up and the consequences of not doing so.

How to use Apache Kafka and Grafana to visualise business process decisions running on the cloud!

Modern business relies on rapid feedback of data and an ability to easily process that data in order to make good business decisions. In this scenario we look at how a government department distributes grants to farmers ensuring that they have the resources that they need to feed a growing population.

Apache Kafka and Grafana you can have a visual representation of the impact of your business process and help to take these decisions across your organisation, be it different silos, applications, regions or more. Apache Kafka helps getting the information across multiple services and locations. This stream of information would then be captured by InfluxDB, which will help organising the collected metrics and then present these using Grafana.
