The landscape for Enterprise Telecom Expense Management (TEM) has evolved significantly as internet networks have become central in corporations. In the past, TEM was primarily focused on managing fixed-line and mobile telecommunications expenses. However, the rise of the internet has led to a proliferation of new communication and collaboration technologies, such as cloud computing, unified communications, and the Internet of Things (IoT). This has made TEM more complex and challenging, but it has also created new opportunities to save money and improve efficiency.

One of the key ways in which TEM has evolved is to become more data-driven. In the past, TEM resources relied on manual processes to collect and analyze telecom data. However, today's TEM solutions use automation and artificial intelligence to provide real-time visibility into telecom usage and costs. This data can be used to identify billing errors, optimize service plans, and negotiate better rates with carriers.

Another key trend in TEM is the shift towards a more holistic approach. In the past, TEM was often focused on managing individual telecom services, such as voice, data, and mobile. However, today's TEM solutions take a more integrated approach, considering all of an organization's telecom expenses together. This makes it possible to identify opportunities for savings that would not be visible when managing services in isolation.

The rise of the internet coupled with cloud adoption has also led to the emergence of new TEM services. For example, many organizations are now using TEM solutions to manage their cloud computing expenses. TEM subject matter experts already possess the reconciliation skillsets needed to effectively manage the new monthly recurring expense. These solutions coupled with management expertise can help organizations to optimize their cloud usage and costs, and to avoid overpaying for cloud services.

Overall, the evolution of TEM has been driven by the need to manage a more complex and dynamic telecom environment. Today's TEM solutions are more data-driven, integrated, and holistic than ever before. This enables organizations to gain better visibility into their telecom expenses, identify opportunities for savings, and optimize their telecom services.
