Show HN: Open IT Maintenance Planner

https://maintenance-planner.vangemert.dev/
13•spmvg•6mo ago
Made and open-sourced a little web-based tool I use to generate maintenance plans for IT. Let me know what you think, contributions are welcome!

Comments

bflesch•6mo ago
I like the simple icons and it feels like a snappy application. Well done.

However, as a new user it's not immediately clear where to click, for example the button in the top left corner which lets you switch between the plan and the diagram editor. Also the small sidebar for inputting the data might not be the most optimal place to do the data input.

What is the goal of the application? What is the benefit of having the diagram? Maybe I'm misunderstanding the purpose but to me it seems like the main output from this software is the "maintenance table", but how do the pointers/diagram help instead of just having a dropdown in the table?

Maybe you can share a more elaborate example and then I understand it better.

Overall, could be more polished but I really like the simplicity and the combination of table & visualization.

spmvg•6mo ago
Thanks for your feedback! I'm not very proud of the data input in the sidebar as well (especially when there is also a scrollbar).

Let me illustrate a bit what my motivation was:

Q: What is the goal of the application?

A: The goal of this application for me personally is to communicate the impact of IT maintenance towards product managers and the rest of the team, in a language that they understand (which is table and architecture diagram).

Q: What is the benefit of having the diagram?

A: Personally, a diagram helps me to understand things better than a big Excel sheet would.

Q: Maybe I'm misunderstanding the purpose but to me it seems like the main output from this software is the "maintenance table", but how do the pointers/diagram help instead of just having a dropdown in the table?

A: You're exactly getting it. The goal is the "maintenance table". I draw the IT architecture diagram (which is how I think about IT in my head), then add periodic tasks to them (maintenance plans), and then it renders the maintenance table automatically. I guess you could also just make a big Excel sheet?

Torwald•6mo ago
This is well done! The UI, the concept…

Another thing. Regarding the field "effort" it is measured in days, it should IMO be measured in hours, or even better yet be user configurable.

spmvg•6mo ago
Thanks!

I like your suggestion. I was doubting a lot between hours and days and eventually settled on days because I noticed product managers (in bigco) making rough estimates based on "fractions of FTEs over a quarter", so days are granular enough for me to get my point across, but maybe people prefer to calculate in hours... I think it shouldn't be so hard to make hours/days configurable in the "Effort" modal.

Dump of related thoughts: - Should hours vs. days be a global setting? Or per maintenance plan? - How many hours are in a day? 8? More? Another config? - People can put fractions of a day (like 0.125). Maybe this is fine already?

Torwald•6mo ago
I think Joels has it right in his assessment of hours vs days: https://www.joelonsoftware.com/2000/03/29/painless-software-...

In another piece somewhere he also states, that the engineer working on the thing should estimate the hours, because everyone has a different skillset and that then relates to the task and how long it takes.

spmvg•6mo ago
This is a really good find, thanks for that. It's from 2000 and still relevant. Added an issue to support hours: https://github.com/spmvg/open_it_maintenance_planner/issues/...
remram•6mo ago
I suspect that it doesn't work on mobile? Otherwise I just can't figure out how to work it.

You might want to include a screenshot of a real-looking plan to give people an idea.

spmvg•6mo ago
Yes I didn't focus on mobile at all, and I notice it renders but drag-and-drop is broken, argh... I think I underestimated how many people would be checking this out on mobile.
spmvg•6mo ago
Thanks all already for the responses and feedback. I posted this to HN a few days ago and I noticed it getting a little traction today. I really appreciate it!

It's way past bedtime here, going to get some sleep and will check later again.
