Profile bio

About Mark De Jong

Many rapidly evolving service delivery organizations face a dilemma: The larger and more complex they grow, the lower their revenue and margin per employee become.As complexity increases the dynamics explode. And that leads to suboptimal staffing, compromised billability, and unnecessary hiring. Why? Blind spots. This makes it very hard to see resource demand shifts, staff current demands without delays, and signal project failures timely enough.The result: an increasing struggle to meet performance expectations, constant feeling out of control, and an unhealthy outlook for the future. This should stop. That's why we created Timewax.Our resource planning platform helps them solve the dilemma by removing 3 traditional blind spots in planning people: capacity blind spots, margin blind spots and future demand blind spots. So they can deliver more work more profitably … without unnecessary hiring.

Listed skills include Project Portfolio Management, Management Consulting, Project Management, Change Management, and 11 others.
