Feel the Fear

Edge Perspectives

I perceive that fear is becoming pervasive and increasingly intense around the world. When I share this perception with others, I often get the response: “What fear? I don’t know many people who are afraid.”. That’s part of the problem. The fear is often not visible unless we know where and how to look for it. Why is that the case?

The Agile Manager

From the COO's perspective, the corporate IT department has hit rock bottom and they keep digging. Very little gets deployed, and the software that does make it live is embarrassingly bad. IT is not exactly a clean canvas. ERP, CRM, document management and other key systems started life as COTS products but have been configured beyond recognition to a point where they can't be upgraded, and they're so ancient they've been disavowed by their vendors.
