It's essential to consider lifecycle costs and employee adoption rates when assessing the ROI of technologies like RPA, AI, or digital platforms.

More detailed explanation, breaking down the key parameters involved in lifecycle costs and employee adoption rates , and how they impact the ROI of technologies : 1. Lifecycle Costs Lifecycle costs represent the total cost incurred from the introduction of a technology through its entire operational life, including purchase, implementation, maintenance, and decommissioning costs. Understanding lifecycle costs helps in estimating long-term expenses and can directly influence ROI. Key Parameters: Initial Acquisition Cost : This includes the upfront investment needed to purchase software, hardware, or licenses. For example, purchasing a new AI-powered system or RPA tool involves both one-time costs and implementation fees. Implementation Cost : This involves costs associated with integrating the technology into existing systems, training staff, and configuring infrastructure to ensure the technology works efficiently within the organization. Operational & Maintenance ...
