This can lead to increased efficiency, collaboration, and innovation, as well as reduced turnover and absenteeism.

Calculating ITRaaS ROI

To calculate the ROI of ITRaaS, organizations need to quantify the costs and benefits over a specific time period, typically 3-5 years. The ROI calculation should include the following components:

1. Upfront Costs: The initial costs of implementing ITRaaS, such as migration, integration, testing, and training.
2. Ongoing Costs: The recurring costs of ITRaaS, such as subscription fees, support and maintenance, and internal labor.
3. Cost Savings and Avoidance: The quantified cost savings and avoidance from ITRaaS, such as reduced infrastructure and facilities costs, labor and skills costs, downtime and data loss costs, and compliance and regulatory costs.
4. Business and Operational Benefits: The quantified business and operational benefits from ITRaaS, such as increased revenue, customer retention, and employee productivity.

The ROI calculation can then be expressed as:

ROI = (Cost Savings and Avoidance + Business and Operational Benefits - Upfront Costs - Ongoing Costs) / (Upfront Costs + Ongoing Costs) x 100

For example, if an organization expects to achieve $500,000 in cost savings and avoidance and $200,000 in business and operational benefits over a 3-year period, with an upfront cost of $100,000 and an ongoing cost of $50,000 per year, the ROI would be:

ROI = ($500,000 + $200,000 - $100,000 - $150,000) / ($100,000 + $150,000) x 100 = 180%

This means that the organization expects to achieve a 180% return on its investment in ITRaaS over a 3-year period.

It's important to note that the ROI of ITRaaS can vary based on the specific needs, capabilities, and goals of each organization, as well as the specific ITRaaS solution and provider chosen. Organizations should work closely with their ITRaaS provider to develop a customized ROI model that reflects their unique context and priorities, and to track and measure the actual costs and benefits over time. By carefully evaluating and communicating the ROI of ITRaaS, organizations can build a strong business case for adoption and ensure ongoing support and investment in this critical capability.
