FROM RETURN ON INVESTMENT (ROI) TO VALUE OF INVESTMENT (VOI)
For too long, the true value of human and organizational development have been invisible to traditional metrics. AATD was established to change that. We provide a new gold standard for performance, grounded in a holistic, evidence-based methodology that captures the complete picture of organizational excellence.

Why ROI is No Longer Enough
Return on Investment (ROI) is a valuable but incomplete metric. It measures efficiency in a linear system, but it fails to capture the complex, multi-layered impact of strategic development initiatives. An ROI-only focus creates a dangerous tunnel vision, ignoring critical performance drivers like:
- Enhanced leadership capabilities and decision-making quality.
- Increased employee engagement and retention of top talent.
- Improved innovation culture and organizational agility.
- Strengthened employer brand and market reputation.
To measure the true impact of performance development, a more intelligent and comprehensive metric is required.

The Gold Standard: Value of Investment (VOI)
At the heart of the AATD Standard is the Value of Investment (VOI). Unlike ROI, the VOI framework is a holistic methodology that measures the total strategic value created by a development program, including both financial and crucial non-financial outcomes.
This is not a theoretical concept. The VOI model was developed and introduced to the industry by the President and CEO of the United States Online University (USOU.EDU), and author of the seminal book, “Value of Investment: New Methods in Educational Controlling.”
Practiced by thousands of leading companies worldwide, the VOI framework is the only proven methodology to provide a clear, comprehensive, and credible picture of performance improvement. It is the bedrock of every AATD accreditation.

The Formula for Future-Ready Performance: HI + AI = SI
Performance is no longer just about human skill. It’s about how effectively human talent is amplified by technology. Our standard validates an organization’s mastery of Symbiotic Intelligence (SI)—the powerful fusion of Human Intelligence and Artificial Intelligence.
- Human Intelligence (HI): We validate the cultivation of core human competencies that technology cannot replicate: strategic foresight, complex problem-solving, ethical leadership, and creative innovation.
- Artificial Intelligence (AI): We validate the proficient use of AI not as a replacement, but as a powerful tool to augment human capabilities, accelerate processes, and deliver data-driven insights.
An AATD certification is the definitive proof that your organization excels at this critical fusion, making you a verifiable leader in your industry.
THE PIONEERS OF TRAINING AND DEVELOPMENT EVALUATION

Dr. Jack Phillips, ROI Institute
The industry waited nearly thirty years for Jack Phillips to come along, who expanded on Kirkpatrick’s idea and developed a system to calculate ROI. Kirkpatrick was truly brilliant in his ability to grasp this concept. Had he developed tools to concretely analyze his abstract ideas, there would be no talk of Jack Phillips and the ROI network today. Neither of these highly respected experts has outlined the fact that the quality of benefits derived from training & development is generally the most important part of this process.
Dr. Herbert J. Kellner, United States Online University
Consequently, the research team at USOU under the direction of Dr. Herbert J. Kellner developed the Value of Investment System (VOI). With ROI, Jack Phillips greatly improved upon Kirkpatrick’s model. At last, with the arrival of the Value of Investment System, it is now possible to subject training & development to a critical, qualitative analysis. This type of analysis takes into consideration derived benefits and paints a complete picture of the effects of training & development.
