Exactly! I have the same experience. It is a source of eternal frustration in the team. I had situations that everyone was crushing it, the team work efficiently and at the end the team had to go through the bashing on retro.
There is an argument that you can always add features to the sprint, so you start small and then extend sprint with additional task. But it does not work, because tasks seem to take all the time that was planned for them.
However, the rituals of SCRUM like retros and groomings taking place every 2-3 weeks is a good thing. It's like hygiene.
That's very good and any ISO 270001 certified small-medium company would need that. But it would be better to have stand alone web interface and not only relay on Slack.
Organisations that don’t use Slack aside, driving this from Slack is a real benefit in my experience.
A system like this lives and dies on the team actually using it, and by allowing them to drive it from where they already are (Slack), we’ve found the team are actually using it and don’t have many complaints about the workflows either.
Funnily we started with a pure web interface. But after testing it with a bunch of orgs we quickly noticed that some people have issues finding the URL where to request accesses or when they found it to finally sign in.
So we came up with the idea of bringing it to Slack: Cool thing is that the user is already logged in and can just interact with AccessOwl. We can easily keep him up2date about his/her access request.
However, I agree we shouldn't solely rely on Slack as orgs without Slack just can't use us at the moment. That's a good point! We already provide an admin interface as web app for easier filtering, reporting etc.
If you are far behind start with Khan Academy. Then there are MOOCs on Coursera and eDX as well. Less interactive but 100% Real deal (and it doesnt mean harder) are course materials often with videos from MIT Open CourseWare. If you are into ML do Gilbert Strang Linear Algebra. It will develop you so much that it can’t be understated. Buy his book and do exams and assignments. If you want to take pleasure in math there are brilliant channels on yt, for example Numberphile. GL man.
