The merging of AV technology with IT and IP has occurred at a pace few could have predicted. This rapid evolution has created a wide disparity of skills and abilities among AV integrators with regard to overlapping into traditional IT territory. Some have adapted and are moving forward, others are struggling, but most are somewhere in the middle. Still, many would agree that global adoption of AV over IP has been slower than expected.
Speeding adoption and management of proposed technology solutions creates an environment in which the best and most sustainable solutions for the enterprise can be the driving factor in technology selections. The technology, rather than ability, can be the driver in these decisions, and AV over IP challenges can be turned into opportunities.
There are a few general principles that are preventing wholesale implementation of an AV and IP convergence. In exploring what is keeping us apart, we can begin a conversation, and maybe define concrete actions that can draw us together and deliver more cohesive results.
Understanding and Adopting IP/IT Practices
AV professionals often do not understand the basics of how IP protocols work, or how to address issues and concerns that reside within the IT department. Conversely, the IP focus is completely different than the AV focus, and too often both sides struggle to reach across the aisle, so to speak. But AV and IT must collaborate for successful IP network convergence.
“Actually understanding and adopting IP and IT practices to enterprise and industry-standard levels have delayed true adoption, in my mind,” said Derrick Kelly, director of technical service operations at Whitlock.
Kelly suggested more robust cross-training between areas where there is overlap. At Whitlock, many senior managers have altered their hiring practices to develop blended teams with different areas of expertise. In understanding one another’s goals, capabilities and limitations, both AV and IT teams become better trained on what works and what doesn’t in terms of both AV technology and IP protocols.
Bandwidth issues are probably the largest point of contention between the two departments. As long as AV is pushing 4K (and beyond!) through the network, there will be bandwidth restrictions. IT is not very happy when the AV group comes in making demands. So if both groups have a better understanding of the needs and abilities of the other, they are more likely to work together for the good of the final product.
As AV and IT continue to merge, it can be challenging to determine where one department’s responsibilities end and another’s begin. If hardware takes up too much bandwidth on the system, who is responsible for resolving that? In reverse, some AV hardware requires sophisticated programming to maximize efficiencies. Who will do that and ensure it works with existing interfaces? What is the best way to communicate what’s needed and how to prioritize the work?
Mark Coxon, sales director at Tangram, insists it’s essential to move away from a siloed view of the world and toward one that allows for collaborative work among IT, AV, furniture, architecture, customers, on-site tech managers, and anyone else whose expertise contributes to a better outcome. The more complex the project, the more critical this collaboration becomes.
“By looking at the whole instead of the parts and working toward partnerships with customer IT teams/end users/decision-makers and all of the important elements of a customer’s team—both internal and external—allows for a holistic approach to the customers’ needs. The more protected and siloed groups are, the less likely true adoption and growth will occur.”
“Some of that does mean checking egos and biases at the door, and going in with an open and willing mindset to provide the best solutions,” Coxon explained. “That attitude removes barriers and allows for better adoption. The more collaboratively delivered projects and systems that there are, the better the products, work and adoption will be.”
It’s important to remember that each side of the equation has a knowledge base that is critical for success.
Partnerships create wins. Kelly explained how the teams at Whitlock have adopted a partnership mentality that has led to success.
“We believe strongly that the customer’s IT team is a partner in our technology deployments instead of a hurdle or adversary,” Kelly commented. “In the past, people avoided certain conversations because the climate was always more of ‘us versus them.’ Now our goal is always working toward the strongest partnership possible for the deployment. There will always be situations where that doesn’t work, but those should the exceptions, not the rule.”
By necessity, that process and relationship-building means taking a longer-term view of the sales cycle, design, and project deployment expectations. Kelley added that at Whitlock, this approach has proven beneficial in providing solutions in line with the current technology, as well as keeping future expectations in mind.
“It’s tempting to fall back to what is comfortable and just wanting to get things completed as quickly as possible—and sometimes with good reason,” Kelly said. “But that continues the cycle of slow adoption. We have to push ourselves beyond our comfort zone on a daily basis.”
Dollars and Sense
Coxon agrees that many integrators have limited IT skillsets, but he adds that margin protection is also driving their mindset. “Some integrators lack the needed skillsets to configure layer 3 managed switches or to determine QOS settings,” said Coxon. “On the other end of the spectrum, many firms shied away from AV over IP—especially the ‘V’ part—because the gross profit dollars of a proprietary matrix switch are much higher. They need to protect product margins to support their business models.”
Making a Change
To smooth the transition of AV over IP, integrators look to senior members of their respective teams to set direction and model the right approach. Depending on the culture of each company, this may be a rapid change or a slow evolution.
“Whitlock has always made choices to look for appropriate foundational adjustments to our offerings,” Kelly pointed out. “Sometimes that involves organizational or structural changes, and the shift to a broader skillset and product offering falls right in line with that philosophy. Innovation is talked about in multiple stages—short term, mid term, long term, etc. A focus on long-term relationships with both customers and manufacturers allows the ability to discuss current and future trends. This, in turn, allows us to work on pain points for us, our customers, and our manufacturing partners. That process helps us understand where we need to adjust and how quickly. If we listen and partner correctly, the shift to new technologies, options, and processes becomes much easier.”
Tangram has focused on developing the needed skillsets in-house, and even leveraging the internal corporate IT department. “We have found strategic partners like Access Networks that have already undergone AVoIP certification with leading manufacturers,” Coxon said. However, he cautioned that it’s important to partner with organizations that share your corporate values. “Access Networks, like Tangram, offers white glove service to help design, configure, and manage networks. With a similar approach to business, it’s proven to be great partnership.”
Communication Is the Driver
Within the company, look to specific subject matter experts to discover which parts of the company understand certain things better, and then shine a light on their capabilities. The team should work together to make sure that the right people are involved in customer and internal conversations, design/sales opportunities, and deployment needs. In this way, there is true relationship development and continual refinement of processes to incorporate AVoIP into day-to-day business practices.
“Communication will help everyone become very familiar and comfortable with IP protocols, managed networks, and timecodes,” Coxon said. “But even more important is the idea of transitioning to a services-based industry as opposed to a product sales-based industry. That will take time and effort.
The debate between open platforms and proprietary platforms continues to rage. Coxon predicted that AVoIP will see proprietary ecosystems fade.
“From an audio perspective, AVoIP is already gaining traction, with products like Dante, AES67, and Q-SYS,” Coxon noted. “Similarly, on the video side, we need more cross-platform devices. A video extender should work with any video receiver, regardless of brand. The proprietary ecosystem and secret sauce models will only last in the short term. Just like the world wide web’s strength was that it was an open platform given freely to all, we need AVoIP protocols that do the same to create one sandbox and encourage the kids to play nicely together.”
Kelly also shared his take on what lies ahead: “Long term, there will continue to be a consolidation toward consistent interfaces, processes, and protocols. A good percentage will adopt standard IT methods and may move beyond AV integration or design firms for delivery and focus.
“If the products continue to become easier to deploy and become familiar to IT teams by adhering to their standards, it will be harder for AV teams to silo themselves from IT or other technology providers,” Kelly added.
True service will continue to be a differentiator within this AVoIP space. In fact, services could well be the differentiator in building successful long-term relationships.
“With services attached, capabilities and flexibility will become the true path forward and the differentiator for the AV integration and design firms over the expanded competitive base of IT and technology providers,” concluded Kelly.
The adoption of AVoIP is only going to grow, so identifying areas where your team needs to better embrace this shift is a great place to start. Education is key, so as training sessions are offered by manufacturers, get all the right players involved so the team can move cohesively toward what lies on the horizon.
