Exam AB-100 Topic 2 Question 77 Discussion

Comprehensive and Detailed Explanation From Agentic AI Business Solutions Topics:
The correct answer is D. Identify and quantify all the development, deployment, and operating costs .
A reliable ROAI analysis must start with a clear understanding of the full cost base of the AI solution. If the cost side is incomplete or inaccurate, the return calculation will be flawed no matter how strong the projected benefits look.
In this scenario, the customer service app will:
* autonomously manage interactions
* escalate complex cases
* learn from historical ticket data
That means the solution likely includes multiple cost layers such as:
* design and development effort
* model integration and testing
* licensing and platform costs
* Azure or cloud compute usage
* data preparation and storage
* monitoring and governance
* security and compliance overhead
* maintenance and retraining costs
* support and change management costs
From an AI business solutions perspective, ROAI accuracy depends on capturing both initial and ongoing costs before estimating business value. This is especially important for AI systems, because organizations often underestimate recurring expenses such as inference costs, telemetry, human oversight, prompt updates, and model lifecycle management.
Why D is correct
Before you can calculate return, you need the denominator side of the investment equation. Without a full cost baseline, you cannot accurately determine:
* payback period
* net value
* savings versus current process
* scalability economics
* long-term sustainability
This is the first step because it establishes the financial foundation for all later evaluation.
Why the other options are incorrect
A). Establish the AI performance metrics
This is important, but it comes after understanding the investment. Performance metrics help measure operational success, such as resolution rate, deflection rate, escalation quality, or response accuracy. They support benefit measurement, but ROAI must first define total costs.
B). Conduct an AI market benchmarking study
Benchmarking can provide useful external context, but it is not the first step in building an accurate internal ROAI model for a specific deployment.
C). Model the customer experience
Customer experience modeling is useful for estimating business impact, adoption, and service outcomes, but it does not come before quantifying the investment itself.
Expert reasoning
For AI investment analysis, the most defensible first step is:
* define the full cost structure
* then estimate operational and strategic benefits
* then apply performance metrics and outcome measures
