A recent blog post by marketing expert and author Seth Godin discusses the tensions between senior and junior management. Godin argues that companies can lose pace with what’s new when senior management continues to make decisions. He stresses that it’s important to bring junior employees into the decision making process – not necessarily because they are younger, but because they will offer fresher ideas to the company. 

Executives that stay with one company for too long are more prone to missing trends because they tend to stick with decisions that are comfortable. 

Godin ends his post with this quote: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is probably wrong." - Arthur C. Clarke
