I find it best to drive this decision through organizational strategy and competences within the business and IT.

For instance:

- What tier is the business and BCP group defining this initiative/solution will fall under. This will provide context when reviewing vendors capabilities against your own.

- What is the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) expected for this product?

- Do you have the in house competences to support developing your own solution?

- Is your IT strategy Cloud first? SaaS first etc.?

- What is the business urgency?

- What is the budget?

- Does this need to be resilient and/or scalable? Goes along with Tier and RTO/RPO discussion.

I would have more if I think on it more, but this is some of the core things I am looking at when reviewing a solution. We actually took these types of criteria and ranked the priority and assigned a weight to each item. Then rank SaaS, IaaS, On-Prem etc to see what would win out.

This is not the end all on the decision, but can provide a level of objectivity to the review.

I am curious if your organization has used code generators in any real way. Not low-code tools, but actual generators like RAD-style scaffolding or Domain Specific Languages. I feel that building simple apps is still as complicated as it was twenty years ago, maybe even more. With everything we have today, why does it still feel this heavy? I would love to hear past experiences, suggestions, or ideas from people who have tried to make this easier in their teams.

I am interested in people who have tried generative AI coding projects.  In your experience, are there project attributes that make generative AI coding capabilities a "good fit"?  Are there project attributes that are likely indicators that generative AI will not result in something useful?  I would think complexity of requirements is a big factor.  If the complexity of the project or its requirements is low - I assume genAI coding can get you within the ballpark.  For instance, logic stores: if your project has critical business logic spread out all over the place and not centralized I think that generative AI would not be able to make sufficient sense of that.
