During the startup phase of the company, it's common for structure and coordination mechanisms to emerge organically, without a clear vision or plan for how work should be organized.
This approach, allthough agile, does not scale very well when the organization starts to grow.
When entering the scaleup phase, the same intentionality and meticulousness that has been put into designing and developing the product, needs to be put into designing and developing the organization.
Being knowledgable and intentional about organizational development ensures that the organization grows into a highly functioning and attractive workplace (and avoids the pitfalls of dysfunctionality).
