Enterprise IT has overseen the implementation of an array of data services with overlapping functionality leading to business inefficiencies. Which of the following is the MOST likely cause of this…

Insufficient information architecture is the most likely cause because it directly addresses the lack of a comprehensive, planned structure for how data services should be designed, organized, and integrated across the enterprise. Without a clear information architecture, different teams or projects may independently develop services that perform similar functions, leading to redundancy, lack of interoperability, and inefficiencies.

While ineffective project management can contribute to issues, it typically relates to execution failures within a project, not necessarily the overarching design leading to systemic overlapping functionality across multiple services.

An outdated service level agreement (SLA) primarily relates to the performance and availability of existing services, not the fundamental architectural design or prevention of overlapping functionality.

An incomplete cost-benefit analysis might lead to poor investment decisions, but it doesn't inherently cause overlapping functionality; rather, a lack of architectural oversight does.
