How do you measure the experience and knowledge of an IT professional? One way is through certifications. Earning any certification is a notable achievement, though not all certifications carry the same perceived worth.

Let's look at 10 ways the cloud will change (and to a large degree already has changed) the world.

No matter which IT field you're working in, there are several skills that are useful for every IT professional to know. Here, seven experienced IT professionals working in the networking, programming, project management, and security fields, share what they believe a...

Look back at the some of the highest paying IT certifications of 2020.

The question of how a project manager working in a functional or matrix organizational structure gets team members to perform is asked in almost every project management class I have taught.

In this series, we are looking at six things that can trip up project managers. We’ve covered the hazards of overcommitting, how to provide feedback, the importance of taking responsibility, staying focused, and what leading from the front can actually look like. Finally, we’ll take a look at handling team input.

This Certification Prep Guide provides an overview of the current Project Management Professional (PMP)® certification and offers helpful tips that you can use when preparing for your PMP certification exam.

The process of subnetting is both a mathematical process and a network design process. Mathematics drives how subnets are calculated, identified, and assigned. The network design and requirements of the organization drive how many subnets are needed and how many hosts an individual subnet needs to support. Binary basics and IPv4 address structure were covered in part one of this two-part paper.

This paper proposes a unifying model for project plans. A distinction will be made between the outputs of project planning and the project plan itself. The significance of this distinction is to allow projects of all types to be described at a high level, in a common language, regardless of the type of analysis used to develop the plan.

The CCNAX - CCNA Routing and Switching Boot Camp is a great option to obtain Cisco Routing and Switching skills while pursuing the CCNA Routing and Switching certification. 

The term "life cycle" implies two things: that a process is perpetual and that the sequence of events is obligatory or uni-directional. There is no beginning or end to a life cycle and the sequence of events cannot change. A seed cannot go directly to being a mature plant nor revert back to the blossom stage.

Project procurement activities are often managed by specialists. By this I mean that the procurement department takes over responsibility for purchasing and contract management from the project manager. As a result of this separation of responsibilities, the steps and stages of procurement are often poorly understood by PMs. In this and the next few blog submissions, I will attempt to shed light on procurement activities and relate these activities to the PMI PMBOK.

The tools described in this white paper are essential PM tools. Tools that will best be used, regardless of the project, are the WBS, communication model, and the precedence diagram. The other tools will be needed depending on the project.

I attended a meeting this week with a customer of mine and a potential new vendor. The new vendor was there to pitch his configuration and setup service offerings for a specific ITSM toolset. My customer has already had one bad experience with an ITSM tool configuration vendor who promised one thing and delivered much less. He ended up with a tool that’s minimally used and not configured to match his business needs. He’s looking for a vendor that can understand his business needs and priorities and quickly help him get his tool configured and working in a short time frame. Then the topic of standard changes came up. My customer asked for examples of standard changes. The vendor responded, “Server reboots are an example of standard changes.”

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicating ideas as well as creating new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

Diane Teare, Global Knowledge's Cisco Course Director, discusses the advantages to taking our CCNA Boot Camp.

Projects are a social endeavor. Traditional project management approaches have shied away from the social advantages a more agile project environment brings. By nature, we are storytelling, pattern seeking and social people. We need colocation to shine truly in a project environment.

The process of learning how to subnet IP addresses begins with understanding binary numbers and decimal conversions along with the basic structure of IPv4 addresses. This paper focuses on the mathematics of binary numbering and IP address structure.

Despite advances in security, hackers continue to break through network defenses. In this hour-long webinar, network security specialist Catherine Paquet will examine the favorite methods and targets of hackers and will introduce you to the different categories of security technologies. In this foundational presentation, you will learn about the benefits of security solutions such as firewalls, VPNs, IPS, identity services and BYOD.

The benefits of a RADIUS server are many. In addition to speed, you receive heightened security with user access monitoring, reporting and tracking functions and personalized restrictions. Setting it up costs less than $60 and this white paper walks you through each of the steps, settings, configurations and the equipment you will need.

Business processes are complicated, and mapping them is not a trivial task. Modelling standards give us the tools to model complex processes, but they do not tell us the best way to approach a model or effectively use the tool. In this hour-long webinar, Global Knowledge instructor Rod Fage will guide you through the best way to develop a model, from determining the goal and scope of the process and measuring its effectiveness, to modelling the process in a hierarchical top-down approach, enabling business analyst to continuously validate the model.

The value of IT certifications has grown considerably over the last decade. Examine the evolution of certification trends, see the top-paying certifications and learn how decision-makers are struggling to hire certified employees.

In support of software-defined networking, Cisco has introduced several products to strengthen networks and meet the increased demand for flexible and cost-efficient solutions. The Cisco SDN solution in the data center is ACI. Outside the data center the primary Cisco solution is DNA.

The traditional network engineering model of configuring one device at a time simply doesn’t scale to the growing needs of today’s network. Cisco's intent-based networks and software-defined networking solutions will enable your organization to meet the demands of network programmability and automation. The result will be greater network agility to support new applications while complying with increasing security needs.

The change we have been talking about for years is here: IT Departments are being torn apart and reassembled in new and interesting ways, as one by one companies make their move to the Cloud. As predicted, IT Pros are being asked to take on new and different roles and to be more involved in the business. In this session, we will look at some of these new roles; what’s working, what’s failing, who is succeeding and who has been left behind. Being an IT professional today is exciting as it is scary. There is lots of opportunity; but so many gaps to fall into. It is time to take inventory and ask yourself: are you well positioned to succeed? Related: Ten IT Skills on the Brink of Extinction

Often, we don't have time to learn the reasons behind the standards we use. But learning what instigated a standard goes a long way toward not only understanding its importance, but also more easily and effectively applying it in your workplace. In this hour-long webinar, Global Knowledge instructor Keith Sorn will discuss common networking standards and explain how they were determined and why they are relevant. He will fill you in on things like why it's important to use proper color-coding standards when making cable and why the length limitations on wired cable are essential. He will also explain new standards, such as power over fiber.

This paper covers the configuration of IP Multicast with Multiprotocol Label Switching (MPLS) including the basics of Multicast with the Group Encrypted Transport VPN (GETVPN).

Depending on the switch vendor, the exact steps will vary on how to set up and configure VLANs on a switch. For the network design shown, the general process for setting up VLANs on the switch is:

For us wireless folks that aren’t stellar routing and switching guys, one of the most daunting network tasks is integrating our WLAN infrastructure with the existing wired infrastructure and its services. Understanding wired design topics is pretty fundamental to installing or managing any network, so it really should be on our priority list to spruce up those skills. To give you a nudge on your journey, let’s talk about DHCP for wireless clients.

While Apple has created many fine things, they were yet to be created themselves when Xerox PARC scientists created Media Access Control addresses. These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below:

Wi-Fi networks have been misunderstood by much of the IT community since their inception. Even the reasons for this misunderstanding are kind of hard to understand. The result has been that myths about 802.11 (better known as Wi-Fi) networks have grown almost as fast as the technology itself. In this web seminar, we'll examine 11 common Wi-Fi myths and explore ways to use correct information to make your networks scalable, secure and satisfying for your users.

A local area network (LAN) provides a path of communication, allowing the delivery of packets of data, voice, or video originating from the sender (logical source address) to the receiver (logical destination address). Ethernet is the most common LAN used. As you start to learn about networking, remember that communication and the movement of large numbers, whether it is people, cars, mail, or network traffic, have a commonality. Everything you know and use in your daily life can be compared to the way traffic moves.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicate ideas as well as create new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

Introducing new talent to an established organization can be difficult for many reasons. Seasoned employees may view the incoming new hires as "too green" or as not having the required skills to contribute in a meaningful way. They may worry about having to "waste time" teaching the newbies things that they should already know or get aggravated when the new employees are not familiar with "the way we do things around here." Additionally, it is difficult to know if the right new hires are being put into the right positions for their interests, abilities and talents. After all, a resume and an interview can only tell a hiring manager so much about the person they are bringing on board, and often talented employees are simply being put into a role that is not a good fit.

Every manager wants to get the most out of every employee and maximize team cohesion and efficiency. Making your team members feel as if they are being heard, understood, and acknowledged is critical to any management strategy. Actively listening to team members’ thoughts, ideas, and challenges drives employee engagement and satisfaction, which drives better results. View the slide deck>>

The driver behind 802.11n is MIMO, or multiple input multiple output. This video explains how MIMO works to double your channel speed by sending two or more data streams over the same channel.

In this hour-long webinar, Global Knowledge instructor and PMP-certified project management expert Daniel Stober will look beyond the triple constraint model and focus on the true essence of project success: stakeholder satisfaction. Many project managers (PMs) fall into the familiar habit of managing based on the constraints of time, cost and scope. While all of these are important, managing them effectively doesn't guarantee project success if the PM fails to conduct proper stakeholder management. To manage stakeholders effectively, the PM has to set expectations. Once expectations are set, the PM must influence the perception of project performance with the stakeholder. Tune in as Dan explores methods you can use to accomplish that goal.

Good global project managers develop their own competencies, and those of their team members. We can use technology to bridge distance, but also focus on the human aspects of culture, work habits, management style, English as a mandated language, communication, and uncertainty. Perform a self-assessment and assess your team members, then look for on-the-job and other improvement opportunities. A good way to learn more about how to overcome these challenges is to become involved in the international community.

Complexity has always been a part of projects. But today, globalization, new technologies and changing markets have combined to add to the complexity. Today's projects have more stakeholders, more ambiguity and more politics than ever, and project managers need new tools and approaches to succeed. Join Alexander Stanisic and Michelle Moore of Global Knowledge for an information-packed hour on how to manage the complexity of the 21st-century project.

Knowledge Management examines how we acquire, organize, manage, share, and utilize knowledge and information. The Internet gives us an overwhelming amount of information on a daily basis — and the volume of information available is growing rapidly! One of the biggest challenges for individuals and organizations involved in project management is to make the best use of this knowledge and information so they can operate more efficiently, improve decision making, and sustain a competitive advantage.

As mentioned earlier, one of the most useful pieces of guidance that ITIL provides relates to the categorization of suppliers. ITIL describes four categories of suppliers:

Keep your project on time and within budget by controlling the baselines, budget, and schedule. View our comprehensive guide to project management, from project scheduling to cost control, from the experts at Global Knowledge.

Lessons learned is a theory, or conclusion, based on evidence at a given time and describes what went wrong (as well as what went right) throughout the lifecycle of a project. Although it’s completed during the project closeout process, it should occur during the entire project lifecycle to ensure all information is captured and documented. Consequences of not having a project review of lessons learned are the increased likelihood of repeating actions that might have caused:

In my last post I discussed aspects of problem management in the context of a real-life situation regarding the first vehicle I owned. In that scenario, and throughout this series of posts, I’ve demonstrated a real-life situation from a standpoint of the incident and problem management processes that ITIL describes.

Effective requirements collection at the outset of the project is the key step that will ensure that the project manager can deliver what is actually expected. In this respect, the business analyst must become a key ally and advisor to the project manager. Most project managers are not trained business analysts, so taking advantage of the skill set that a business analyst can offer can greatly enhance the possibility of project success.

In 1998, the Internet Engineering Task Force (IETF) released RFC 2460, outlining the technical specifications of IPv6, which addressed the shortcomings of the aging IPv4 protocol. As with any evolution of technology, new elements exist in the protocol that may seem strange and unfamiliar. This certainly includes address representation, space, and so forth, but also includes a number of different types of addresses as well. A subset of these new addressing types has corresponding types in IPv4, but many will seem significantly different. The purpose of this white paper is to examine addressing classifications in detail and outline their functions within the context of the protocol.

As with the adoption of any new technology, the move from IP version 4 to IP version 6 will take a number of years to complete. During that transition phase, various mechanisms will be necessary to continue support of the older protocol as the newer gains widespread momentum. In addition, there has been some evolution even within the availability of these mechanisms, some of which have already passed from general use into deprecated status. Network engineering professionals already proficient in the use of IPv6, as well as the available coexistence mechanisms, will undoubtedly stay in high demand throughout this process.

The first big push toward implementation of IPv6 was mobile devices. Now, one of the driving forces is the Internet of Things. As the name implies, this means everything, including machine to machine communication (M2M).

This power session is an introduction to Managing Stakeholder relations. It offers new ways of managing and dealing with projects, which focus more on communications, understanding stakeholders' needs and managing their expectations, as well as learning about organizational politics and culture, and performing value-add activities. It provides a practical approach to managing issues that matter most for project success - communication, stakeholder expectations, risk, change and quality; so that the scope, schedule and cost end up on target, achieving the desired outcomes for the organization.

We already covered the first three of the twelve advantages of Agile software development. These three advantages focus on team development and refining the process. Advantage #4: Motivated Development Team The positive relationship with a reasonable and satisfied customer is only one of the reasons why many developers prefer to work on Agile projects. The other main contributor is that they tend to value working in self directed teams (which the Agile methods require for success).

There is a reason why the Agile methods are becoming mainstream. They can work! Although every Agile practice is not necessarily appropriate for every organization, each practice has delivered real value to many organizations, and some Agile practices can be used by anyone! This four part series explores twelve ways in which the Agile methods are valuable. I’ll bet that you will find more than a few that could be valuable for you!

For a project manager (PM) who has served as a military officer on a battalion or higher staff, the parallels between the military decision-making process (MDMP), the orders production process, and project management doctrine prescribed by the Project Management Institute (PMI) are difficult to ignore. Both the MDMP and the processes outlined in A Guide to the Project Management Body of Knowledge—Fifth Edition (PMBOK® Guide) are iterative in nature, allow for the introduction of changes to the original plan, assign tasks and responsibilities, and involve the concept of managing the scope of the operation or project.

Now that we have looked at the similarities and differences between the first two steps of the military decision-making process (MDMP) and the project management processes from the planning process group that align with them, it’s time to take a look at the third ste...

Are you prepping for the PMP exam? What should you know about the impending new edition of A Guide to the Project Management Body of Knowledge PMBOK® Guide before scheduling your examination?

Quality, as we know it today, is an accumulation of several concepts that together create a comprehensive approach to quality. The views of quality, as described in A Guide to the Project Management Body of Knowledge (PMBOK® Guide) and tested on the PMP® exam, focus primarily on the work of three major contributors: W. Edwards Deming, Joseph M. Juran and Philip B. Crosby.

You are estimating the total project cost using three points for cost estimates with a 95 percent confidence level. What is the cost estimate range if the estimated project cost is $120,000 and the standard deviation is $2,500?

Your organization and a seller have just agreed to a contract with a total cost of $150,000, an estimated profit of $10,000, buyer/seller sharing of 70/30 and a ceiling price of $170,000. What is the PTA (point of total assumption)? A. $170,000 B. $160,000 C. $164,2...

You are the project manager on a construction project where you are deliberating between renting, leasing or purchasing a large piece of equipment. Equipment pricing: Rent at a cost of $2,500 per day; Lease for a 60 day period at $2,500 per day, with a 10% discount; Purchase at a price of $100,000. By looking at your project schedule, you have estimated that you will use the equipment about 50 to 60 days. Based only on price, which decision would you recommend?

Whether you're a Project Manager or a Business Analyst, you can certainly relate to a situation where you've felt like your cohort on a project was from a completely different planet! This panel discussion webinar between our PM expert, Ori Schibi, and our BA expert, Cheryl Lee, will explore some of the misconceptions that each role has and learn how to play nicely with each other in the project world.

In many organizations, the Program/Project Management Office (PMO) is viewed as purely a cost center, so it becomes marginalized by additional layers of bureaucracy, oversight and cost. But the essence of the PMO and portfolio management in general is to add value to the organization. So how do organizations reconcile the cost of the PMO versus the value it adds? The short answer is to flip the conversation on its head and talk about the PMO as a revenue driver rather than a cost center. In this hour-long webinar, Global Knowledge PMP-certified senior product manager Daniel Stober will explain how, by focusing on efficiencies gained and reduced waste, you can shift the conversation from the PMO being a necessary evil to the PMO being critical for organizational success.

Today, every project comes with limited resources and an impossible timeline. You have to prioritize, but how do you determine what's most important? The answer is to do more than just prioritize. You have to fully understand your company's strategic direction and make every action align with that strategy. In this hour-long webinar, project management expert Yvan Bastien will show you how to reach that full understanding and make the kinds of informed decisions that lead to success.

In this hour-long webinar, Global Knowledge instructor John Barnes will guide you through implementing Cisco private VLANs. He will review VLANs and 802.1q, and he will discuss private VLAN fundamentals and operation, covering primary VLANs and secondary VLANs. He will cover VLAN mapping and discuss using private VLANs between multiple switches. He will also provide a use case example.

Change managers and project managers come at the same goal of maximizing ROI for their organizations, but from different perspectives and approaches and with different skill sets. While project managers are responsible for achieving specific objectives on time and on budget, the change manager's role is broader. Change managers apply a structured approach to helping individuals, teams and organizations negotiate relentless change. A project manager turns ideas into reality. Increasingly, project managers are required to take on the role of change manager as well. Business today can't afford to carry out tasks without considering the larger picture. Today, integration is unavoidable - and expected. In this hour-long interactive session, we'll discuss the similarities and differences between project management and change management. We'll also identify the occasions when both a project manager and a change manager might be needed.

Agile project management literally turns the world of managing projects upside down. The triple constraint is balanced in an unconventional way, the role of the matrix team coordinator is downplayed, and risk management can be built into the prioritization approach. So, what is left for the PM to do?

Project Scope Management sets the foundation for the creation, development and successful delivery of a project. Learn about the project management process here.

Most project team members report to a functional manager who controls their assignments, performance appraisals, raises, bonuses, etc. Until recently, project managers (PMs) had little input into any of these processes.
