How do you evaluate the return on investment of your cloud data projects?

First step is define business sponsorship, business owners and a high level outline of data products/ use cases including use of solutions like Gen AI

Defining clear objectives and success metrics is the critical first step in assessing your cloud data project's ROI. What specific business goals do you aim to accomplish - reduced costs, increased revenue, better customer satisfaction? Ensure your metrics directly measure progress toward those goals and align to overall strategy. Well-defined metrics should meet the SMART criteria - Specific, Measurable, Achievable, Relevant and Time-bound. This concrete foundation enables accurate tracking of outcomes versus targets. With crisp objectives and metrics guiding your path, you can reliably evaluate if your cloud data project's delivering the expected ROI and business value. Monitoring aligned metrics makes course corrections smoother too.

Before going into the details and putting security on the side for the moment, the first think you should ask your teams is : can you do what you do faster and/or better and/or easier. Using Time as your default metric as the advantage of focusing on a universal ressource, that is finite for everybody. Ask your teams to compare the way it was done before and the way it is done know and if there is no change... make it happen. The rest will follow.

Estimate both costs and benefits - the cornerstones for cloud project ROI analysis. Tally all direct expenses like hardware, software, migration, costs around integration, security, training. Benefits can be tangible like cost savings or revenue increases, but also intangible like improved quality and innovation. Take a long view - consider how costs and benefits may evolve over time as needs change. And be realistic about risks - factor in uncertainties that could impact your projections. A rigorous upfront analysis of estimated costs and benefits establishes your business case and expectations. With eyes wide open to the full range of costs and benefits, you can evaluate if the ROI merits the cloud investment.

To quantify ROI, a common approach is the Net Present Value (NPV) analysis, which discounts future cash flows to current dollar values for an apples-to-apples comparison. If the present value of benefits exceeds costs, you get a positive NPV and green light on ROI. Consider multiple indicators - NPV for overall value, payback period to recover costs, break-even point for profitability. Use ROI calculators to model different scenarios. And remember ROI is an estimate, not a guarantee - keep quantifying and tracking post-deployment to validate. Armed with rigorous ROI projections, you can make data-driven decisions on cloud investments. But use ROI as a guide, not gospel - continually verify delivered value matches estimates.

Compare continuing on-premise operations or hybrid models to shifting completely to the cloud. If going cloud, analyze tradeoffs between providers - weigh strengths of AWS, Azure, Google Cloud against your architecture, budget, needs. Plot each path against your objectives, metrics and total costs. Factor in opportunity costs - the value forfeited for alternatives not chosen. This deliberate, structured approach prevents tunnel vision. And it may reveal hybrid solutions blending existing systems with selective cloud components as the optimal course. Evaluating multiple angles illuminates the pros, cons and trade-offs of each potential road. So confidently choose the best path – cloud or non-cloud – by exploring all options.

ROI analysis isn't a one-time deal. Continuously track performance, costs, benefits. Collect feedback, adjust, optimize. Stay agile, respond to realities. Monitor, review, fine-tune. ROI's ongoing dialogue between data, systems, and value.
