I can't resist to point out that, in theory, there are at least two other options avoid wasting many resources via the failing new teams:
1. Get the original dev to explain his theories (keep employees longer or engage them as consultants)
2. Make and get a "diary" of the original devs theory building.
In this story, and in probably many places, the business environment however supports the explained outcome.
I agree that it seems harsh. However, I have tried the "whitelist this app" route. Turns out that, at least for me, the parental control on android is not sufficient. For example, you cannot block the app store, and in the app store you can watch video previews of games. Also, you get to watch animated gifs on every text field.
Good points. However unlocking the phone in the morning puts my son on the wrong track: you would be surprised how much time one can spend checking animated gifs by using any text field that will inevitably be unlocked as well.
Of course I will take full responsibility in case of bugs... So far it didn't happen.
I applaud your efforts to keep your son from being addicted to screens.
While I'd be more conservative in the setup (I'd probably go with a device without inputs that turns on just to browse to a website directly, making any browsing mistakes or changed layouts less impactful), I do wish there were better alternatives for parents than "hand your kid a smartphone".
In an ideal world, schools would use some kind of one-way messaging devices to get the benefits of modern technology without the addiction smartphones bring, but I don't think we'll see that any time soon. Perhaps something like a (locked-down) Remarkable e-Ink tablet with a cellular network connection to receive school notifications and schedule updates as well as for doing homework in could prove quite useful, but that also sounds way too expensive for schools at the moment and you'd need to lock it down so that it's no more distracting than a piece of paper.
This is a nice project, but personally I'd favor demanding that the school come up with an alternate solution for your son that doesn't require you to supply smartphone. Rather than allowing them to shift the burden to you
Why would there be so many changes? Do they seem legitimate, or more like they are trying to justify spending money on the scheduling system and playing with the new toy?
It is more related to sick leave and general scarcity of teachers. I guess before the existence of timetable apps they were better in finding creative ways around those changes.
In my experience, teacher absences just meant substitutes, another teacher swapping over / handling two classes, or an impromptu class period spent watching something on tv.
I'm not sure that was much better than just telling the students in advance when you know a schedule will change and sending them to the library to study or etc.
I think it is getting better year after year, in small steps. For example, B2B taxation within the EU (by use of the reverse-charge mechanism) has become quite easy in recent years. Of course, depending on the product, diverse local rules may apply.
