Landmines to avoid when selecting a TEM

Andrew Hartwyk, Senior Research Analyst


No single TEM vendor offers the best solution for all enterprises because TEM vendors, like enterprises, are unique. Selecting a TEM vendor by matching features and benefits with business requirements is critical to sustainable relationship success. Focusing on business requirements and the delivery capabilities of vendors will yield fruitful results. Conversely, selecting the lowest price without regard to proper solution alignment can doom a relationship. This Analyst Perspective report helps enterprises avoid cost-focused selection pitfalls and other selection landmines by sharing keen insights that influence positive TEM vendor selection results.

According to AOTMP Research & Advisory, just more than half of enterprise respondents have a relationship with a telecom expense management provider, while a little more than a third want to change providers within the next 24 months, or at the end of their current contracts (see Figure 1 sidebar).

This indicates a gap in vendor service delivery or enterprises not selecting the best partner for their environments. Given the evolving state of telecom environments, finding the right solution can be a challenge. As enterprises invest in the next wave of technology, they expect their vendors to provide consultative leadership and guidance, and ensure correct implementation and management in accordance with business goals. This can only be done well when collaborating with the TEM vendor. Luckily, as AOTMP Research & Advisory has found, most vendors are eager to become more engaged in the tactical planning and strategic deployment of their clients’ new services.


Enterprises that understand the makeup of their telecom and mobility environments are better positioned to select the correct TEM vendor. For organizations that are seeking outsourced assistance for the first time or that are leaving a vendor due to lapses in inventory and management practices, taking the time to baseline inventory and invoices will improve engagement with a TEM provider exponentially. 

Doing this also helps an enterprise to pinpoint the types of services it is seeking in a TEM provider. As noted in the 2018 TEM Market Landscape from AOTMP Research & Advisory, the enterprise engagement style with vendors still varies (see “TEM Vendor Configurations” below);  however, more enterprises are choosing fully outsourced BPO or technology and managed services. That way, their professionals can focus more on strategic, revenue-generating projects rather than mundane daily activities.

The type of engagement an enterprise seeks with a TEM provider is not exclusive to the technologies deployed. Many TEM vendors are proficient in managing the various technologies in telecom environments. But enterprises must also consider the factors of culture – self-service versus managed services, help desk support structure, inventory management practices, IT service management policies, and the level of telecom management training for employees. Organizations that do not account for these components may well find themselves stepping on more than one TEM landmine.

Enterprises must also understand the condition of their environments and the elements that influence them. Realizing the need for services and then using them can be two separate challenges in themselves, but the process starts with knowing what the organization needs. Therefore, AOTMP Research & Advisory recommends completing service proofs of concept, wherever possible, prior to contract negotiation. This allows an enterprise to test the apparent service delivery methods of the vendors under consideration and identify the vendor that best meets the unique challenges of the business. This helps steer an organization away from the wrong TEM vendor fit – another landmine best avoided.



The vendor provides software-as-a-service (SaaS) or on-premises software, the enterprise performs all the work.


Via SaaS, the vendor loads carrier invoices while the enterprise handles all other work.


Through SaaS or on-premises software, the vendor does everything specified in the statement of work, while the enterprise handles whatever the vendor does not.


The vendor assumes all TEM work streams, including bill pay, and the enterprise receives the results.


The vendor completes specific telecom management tasks (contract negotiations, technology refresh, project management, etc.) on a project basis.


Enterprises making robust change based off an initial audit that did not verify inventory has led to critical errors. For instance, say a circuit was mislabeled and not caught during inventory validation. Trying to shut down that circuit later to save money could result in call center downtime. Or say a router was misidentified and later shut down to save expenses – and that router controlled the corporate Wi-Fi network. Avoid this landmine first by verifying all inventory and, second, by viewing services and assets as strategic, rather than commodities to immediately be eliminated. That way, the enterprise will only shut down telecom components that have proven they do not serve business outcomes.


When speaking with enterprises, each one differentiates itself from its peers – different needs, different vendor management and accountability practices, different vendor treatment methods for scope creep, etc. – and AOTMP Research & Advisory observes this same reality in its enterprise engagements. Divergent client requirements push TEM vendors in new directions while also demanding better outcomes from their standard service delivery. This is less extreme for some vendors than for others, but not a single enterprise AOTMP Research & Advisory spoke with could hold back about one key frustration: Overwhelmingly, enterprises are vexed by inventory and invoice inaccuracies, and by limits to their TEM vendors’ platform reporting capabilities.

Not surprisingly, the reason these areas cause upset varies widely, but enterprises are most frustrated with a lack of reporting creativity and access to the APIs that provide core TEM data to other systems. After recently reviewing the TEM vendor landscape, AOTMP Research & Advisory sees the tide in these two areas changing among vendors. Many vendors are strategically selecting third-party systems to integrate with based on client demands and making those latest reporting capabilities the focal point of their go-to-market strategies. And yet, the feedback from enterprises indicates a communication gap that has become prevalent in an industry bustling with new technology investments, and robust merger and acquisition activity over the last 24 months. While vendors are investing in improved technology capabilities to support clients, some lack the service delivery depth to ensure existing clients – the ones demanding the change – are properly informed and implemented. 

To continue to hear from enterprises about the lack of accuracy within invoice processing and inventory management is painful. After all, one of the paramount best practices of telecom management is to nail the basics of inventory and invoicing. 

While the blame may not rest solely on the TEM vendor, that may still be unacceptable to enterprises that outsource the bulk or all of their telecom management activity, including bill pay. Consider the point made earlier about the lack of depth in service delivery – critical breakdowns are dismantling client relationships despite advanced technology capabilities. Technology will not fix broken client relationships regardless of who holds the lion’s share of blame for service issues. Technology will aid in the improvement of client relationships when coupled with knowledgeable, consistent service delivery agents. 

Enterprises that continue to experience problems with invoice processing and inventory management must use a scorecard that measures vendor performance and tracks the vendor’s ability to effect change. The scorecard can establish a baseline for engagement with a new vendor or help the enterprise to implement service level agreements at contract renewal time to hold the existing vendor more accountable. If the enterprise is not willing to engage in more measured management of the vendor and create the mechanisms for accountability, then it is accepting the lack of accuracy regardless of the level of frustration. 

Finally, in addition to the above, AOTMP Research & Advisory heard from enterprises peers seeking global coverage. The meaning of “global” can vary wildly for enterprises, ranging from feet on the street across all major regions to local language help desk support. Any oversight in correctly matching a vendor’s global capabilities with enterprise requirements will toss a landmine into the service delivery process, and impact the relationship. Therefore, enterprises must carefully consider their environments and demographics.


As the TEM market matures and vendor tenure with a client grows, the relationship should continue to evolve as well. This can be a critical component of the success of an enterprise’s telecom ecosystem and strategy, especially when telecom is managed as a strategic asset, rather than just as a means for saving money. After all, when viewed and administered through the lens of productivity and efficiency, telecom contributes to key business outcomes, including higher profit margins and expanded competitive advantage. 

With that in mind, enterprises must decide how they want to interact with a TEM vendor. Some are waiting for their TEM providers to saddle up and take charge of the environment – to act without waiting for direction, to not tip-toe around the truth and wait to implement the painfully obvious. Conversely, others are quick to exert control over a vendor as a way of ensuring authority over the decisions impacting their environments, which highlights the overarching theme of this report: every enterprise is unique. Enterprises must choose one approach or the other. Either embrace the vendor’s abilities and choose to trust its expertise, or continue to develop the internal expertise that will contribute to ongoing gaps in the telecom ecosystem.

Global can be a rabbit hole that is best served by its own report – refer to AOTMP Research & Advisory’s forthcoming report European TEM Market Landscape, for examples of providers based outside of North America. Overall, more enterprises are demanding that TEM vendors’ global services rise to greater heights.


“I feel like they want us to succeed in our work as much as we want to. That is a good feeling to have,” one enterprise telecom management executive recently told AOTMP Research & Advisory. This testimonial speaks volumes to the value of the relationship and the level of engagement possible when both parties come to the table and work together. 

Across the board, the industry is showing the signs of life and improvement that enterprises have been demanding. When TEM vendors meet enterprises’ basic needs, a lot of excitement about the vendor and its results can arise. Businesses are eager to see the opportunities found in an invoice audit or optimization. 

They may lack the confidence to implement those discoveries and leave some savings on the table, but they appreciate the accuracy when it’s there. 

Plus, a proactive TEM will guide the organization in acting on the results and making the most of them. Altogether, these outcomes provide the enterprise with validation of the TEM provider’s contract and offer the opportunity to build the business case for deeper engagement.

Perhaps surprisingly, AOTMP Research & Advisory also received some positive responses to the recent merger and acquisition activity within the TEM market. Where managed appropriately, with new platforms acquired or capabilities added, this activity can have positive consequences on client engagement. AOTMP Research & Advisory must emphasize this was not widespread feedback; rather, it stood out as an example of a well executed service delivery transition amid M&A. TEM consolidation can benefit enterprises when overseen correctly, and when vendors engage clients in training and implementation of any new technology.  

Enterprise respondents further indicated that they are attracted to the consolidation of data sources happening in the market, whether that comes from TEM vendors adding more data to their native platforms or whether they integrate with critical third-party enterprise systems (i.e., ITSM, finance, human resources, etc.). As AOTMP Research & Advisory has discussed in recent reports, many TEM vendors are adding cloud management, “enterprise of things” management and communication lifecycle management to their primary service capabilities. This is helping enterprises to engage more with their vendors.


Each enterprise will approach TEM to solve to its own problems. However, considering advice from peers who have lived through similar implementations can make the process easier. Here is some insight AOTMP Research & Advisory gathered from enterprise respondents in October 2018:

Avoiding landmines when choosing a TEM requires willingness to investigate vendor possibilities in-depth. This takes time. While cost will always be a core reason for using a TEM, it should never be the only one or the main one. Thus, the enterprise telecom management group must present the business case that convinces executives to allow three to six months to vet vendor candidates that emphasize far more than saving money. 

Look for TEM vendors that want to contribute to business outcomes such as helping the enterprise to increase its revenue, customer retention and market share. Acting on the best practices noted throughout this report, and covered in others from AOTMP Research & Advisory, will help the enterprise whittle down its list of potential TEM vendors and ultimately land on the one that will best serve its long-term goals.
