Excel used to be, and probably still is, the primary competitor to enterprise-developed apps - a lot of businesses run on it. But, that was a locally deployed phenomenon, with an added ability to deploy it somewhere else by simply emailing the workbook to someone else.
In your organization, how do your managers turn their code into working software?
Some users with privileged access can run their app locally in cli or browser, else most softwares we work with can use custom modules in specific languages (html, css, js, dax, vb.net, perl, python, sql, etc.). Ownership and trust must be established, for example only the commercial manager has access to deploy modules to CRM. They usually are constrained to read access, unless they are informed engineering managers.
Ideally I would share pipelines to deploy static pages, or a predefined dynamic architecture. I'm wary the security risks are too great, I don't trust they would have enough time / interest to become autonomous in unconstrained environments so I didn't pursue the idea, maybe I could for static pages, or in isolated networks ..
