Each protocol has its own pros and cons, and works better in some situations than others. In this paper, we explore the strengths and weakness of RIP, EIGRP, OSPF, and IS-IS, and discuss when it is appropriate to use each. We will evaluate each protocol in terms of five criteria: • Convergence speed • Ease of use • Network topology required • Vendor support • IPv6 support...

A meeting will not be successful unless someone has put some effort into its planning. Most meetings are undermanaged. If any other business activity were as poorly managed as the average meeting, those responsible would have their careers seriously abbreviated. The effectiveness, productivity, and ultimate success of a meeting is directly related to the amount of planning. Someone must take management responsibility seriously. This paper introduces the four stages of meeting management: planning, preparation, process management, and follow-up.

In a 2004 survey of 200 IT professionals from 14 countries in the Americas, Asia/Pacific and Europe, the IT Governance Institute (ITGI) found that in 80% of organizations, IT management is solely responsible for defining and addressing IT risk impact. This widespread lack of involvement by business unit managers demon- strates a consistent—and alarming—gap in mapping technology risk to the business. Additionally, this gap als shows that most organizations have inadequate IT risk assessment processes across their enterprises.

Understanding the current state of your storage infrastructure—what capacity you have, where it is located, who is using it, who is paying for it, how efficiently it is being used, and how well it is meeting SLAs—is fundamental to intelligently planning, provisioning, and managing storage. Buying and deploying storage as it is often done on a per-project basis— based on loose estimates of immediate and future required capacity, application requirements, and response times—typically results in over-purchasing of hardware and poor allocation of resources.

Management is delegation. Either learn to delegate or you will be buried in work that others could, and should, be doing. ‘Managing’ is the alternative to doing something yourself. Management responsibility is the del- egation of tasks to others, and the control of outcomes. If you could get everything done your- self, there would be no need for staff. If you cannot do everything yourself, there needs to be delegation. If there needs to be delegation, then someone must manage the assignments....
