Sometimes the order does matter for the task, like if you're doing something on the computer or a phone that NEEDS to be done in a certain order or the desired result won't occur.
If someone is showing me some such task, and they leave out a task that, to them, seems intuitive but doesn't to me because I haven't done it before, then it'll take me longer to learn. For instance, a boss once was trying to teach me to do a cash flow worksheet, and I had minimal Excel skills and didn't realize you'd have to do one particular thing to get the final results. She thought I'd know that and left it out, so I was having problems.
If it's anything mechanical, or even computer-related, I'm always so afraid I'll screw up that I wonder how I ever learn anything.
I haven't been on a job where I had to be in a work group yet, and I'd be terrified to be in one because 1. The people would probably not like me; 2. I might not know as much as they did and they'd be upset. 3. I might redo something someone else had done and they'd think I was trying to take credit. 4. I might not learn at the same rate as the others and slow them down and they'd hate me. 5. They'd probably all go out to lunch or a drink after work and exclude me. If they did include me I'd think they were doing it out of pity and would be afraid to go. 6. If work groups formed and dissolved all the time for various projects, I'd be the one person that no one wanted on their group, and it'd be like being chosen last at recess or for teams in gym.
I wouldn't care what order they did stuff in, as long as it got done. Sometimes if I'm doing stuff on my own I do it in a particular order because I'm used to it, but then if someone comes along and shows me a more efficient way I'll make the change. The one thing I would probably say I was order-conscious about would be the social thing..that at some poiont they'd want to go to lunch or for a drink after work and relax, and not invite me, and I would imagine this was going on even if it wasn't (for instance, they might not be the type that care ot socialize with co-workers; they might need to go pick up their kids, or whatever, and just not be doig anything. But I would think they probably were and just didn't want to or forgot to invite me.
