The demand for skilled business analysis (BA) professionals is on the rise, and a great way to declare your expertise is with a BA certification. But which BA certification is right for you: PMI-PBA, CBAP or CCBA? Here is a look at the eligibility requirements and steps for obtaining each.

Kirsten Lora, Global Knowledge Senior Product Director, explains why business analysts are essential to organizations and how our Business Analysis Essentials and Business Process Analysis courses can help them in these roles

Kirsten Lora, Global Knowledge Senior Product Director, explains the difference between our Business Analysis Essentials course and Business Process Analysis course.

Communication is vital within projects and contributes significantly to project success. PMs and BAs have important—and different—roles. Let's take a look.

Instructor Carol Kavalla talks about the advantages of taking a Cisco Data Center Unified Fabric Implementation class from Global Knowledge.

Enterprise thinking, simply put, is the practice of considering the entire enterprise in decision-making, not just a given group or department. This style of thinking makes the organization both leaner and more agile—lean by reducing the waste and inefficiencies that come from blinkered and siloed thinking and agile by increasing everyone’s understanding of enterprise goals, vision, and functions.

Enterprises, whether they are commercial, non-profit, or government entities, are operational organizations that operate through the execution of hundreds of processes. The quality of these processes affects every aspect of the enterprise and these processes are rarely static. Business Process Analysis (BPA) is the discipline of examining processes so that they may be changed to align with enterprise objectives.

That depends on their configurations. For example: While it makes very good sense to include redundant physical links in a network, connecting switches in loops, without taking the appropriate measures, will cause havoc on a network. Without the correct measures, a switch floods broadcast frames out all of its ports, causing serious problems for the network devices. The main problem is a broadcast storm where broadcast frames are flooded through every switch until all available bandwidth is used and all network devices have more inbound frames than they can process.

As we discussed previously, Cisco created the Nexus Operating System (NX-OS) to power its next-generation data-center switching platform. While this new OS shares many similarities to the original IOS, there are some definite differences that you need to be aware of as you begin using it.

“Twisted Pair” is another way to identify a network cabling solution that’s also called Unshielded Twisted Pair (UTP) and was invented by Alexander Graham Bell in 1881. Indoor business telephone applications use them in 25-pair bundles. In homes, they were down to four wires, but in networking we use them in 8-wire cables. By twisting the pairs at different rates (twists per foot), cable manufacturers can reduce the electromagnetic pulses coming from the cable while improving the cable’s ability to reject common electronic noise from the environment.
