I work for a non-tech-focused small business that has grown from 50 to 75 people over the past year. Our CTO (title inflation) has always primarily been in charge of infrastructure but much out of it is outsourced and she primarily handles tickets and on-premise gear. Support requests go unanswered, other users assume tech support in order to keep things running, and things break constantly. Without getting into too much detail, a good recent example is a work stopping, critical outage a few months ago where she did not communicate with the firm at all, and no resolution timeline or post-morterm was provided.
This has been barely tolerable over the years but she is not the right fit for the growth of the business. Additionally, she is not involved in the development process at all and this has proven frustrating for recruitment (candidates are confused by hierarchy/red flag) and coordinating on infrastructure needs; developers need to do a ton of work before they can even start writing a single line of code. There's an additional worry that developers are going to get pulled more and more into supports needs given that the person in charge of support lacks the technical ability to do so.
The audience I want to communicate with lacks a technical background, has a very hands off management style, and a pretty short attention span. I want to illustrate that this person is not the right fit for the growth and future of the firm and that they introduce a ton of friction into several teams actually just getting work done. Without overwhelming people, what is a good way to communicate this in a concise, non-ranty manner?
Edit: To be clear, without going into a ton of detail, I am very confident that this will not blow up in my face and that leadership is just not aware of pervasive these issues are and how large the spillover efffects are. I just want some advice on how to properly communicate with this particular audience in a way that they will understand. I won't have multiple opportunities to bring this up without coming off like I have a grudge so I want to make sure the first time is properly handled.
However the organization management got to where it is, trying to get a senior manager/director removed by rational argument presents a high probability of blowing up in your face. The facts may not matter nearly as much as the perception you got out of line and threatened the hierarchy. You might get fired for rocking the boat.
In other words, think very carefully before you act, and make sure you can die on that hill. In my career experience less than competent managers survive and punish those who challenge them.
I don’t know enough about your situation, but the incompetent CTO may present an opportunity for you to step up and take charge, without directly challenging their authority. Have you thought about offering to take on some of the responsibility?
2) It is possible that the CTO doesn't care, but it's also possible that they care but just don't know what to do about it. If the CTO had an assistant who was good at managing things, they might be willing to let that assistant do the things they aren't. Convincing the CTO to get an assistant to manage stuff like support requests, infra needs, etc. might fix the problem. She may also be actually good at very high level stuff you don't see, like for example relations with other CxO's, at your company or customers.
