When companies grow their ways of work stop being effective. For example, while a tightly-knitted team could manage a small number of customers, as each member becomes busier they can no longer rely on memory and important information is lost. Effectiveness also drops when team members make improvements to their own working methods and those changes compromise the team.
I like to fix things, best of all with the people who are impacted by change. For businesses that are growing this form of help can range from facilitated sessions to design new processes to better communications to customers or detailed process development.
