Being Agile is very important to be flexible, fast and succesfully work together. I believe this is not a trend, but here to stay and that interaction models like Scrum, DevOps or SAFe can help you in becoming more Agile.
A lot of companies use Agile approaches like Scrum, DevOps or SAFe. This might lead to applying a technique, rather than truly adapting the mindset: understanding Agile is different from being Agile.
It is not difficult to understand the Agile Manifesto, but already more difficult to apply it and even more difficult to live according to these principles. But here is where the real value shows up: where customers are at the heart of your company and employees understand their contribution in the whole. I believe this is not a trend, but a Philosophy that lasts and I can help companies step by step with this Cultural Transformation.
