Who is responsible for the team not functioning well? How are they creating problems

Bill didn’t sleep very well that night. He kept waking up with the same thoughts running through his head. It was the third morning in a row he was groggy from sleeping poorly. Most of the other team members were already sittingaround the table in the lab when he arrived. Sue was diligently studying for a test later that afternoon, and Tyler was talking to his fiancée on the cell phone. Both of them nodded to Bill as he came in. Fifteen minutes later, and ten minutes after the meeting was supposed to start, Tyler called Rachel, waking her from a sound sleep. “Man, I always have to call her and wake her up. This is really unfair. She has no regard for any of the other people on her team” said Tyler after hanging up the phone. “I don’t even know why we put up with her not showing up.” Another half hour went by before Rachel, dressed in sweatpants, arrived in the lab. “Sorry I’m late guys. My alarm clock didn’t go off again this morning. I need to replace that stupid thing, but my mom hasn’t sent me a check for this month.” “That’s O.k., Rachel” said Tyler. “I have trouble with my alarm clock too. I think the stuff they sell at Wal-Mart breaks really easily. I stopped by Daylight Doughnuts and picked up a dozen. Go ahead and have one. It will help wake you up.” “Thanks, Tyler. You are a great guy to have on a team.”  “Let’s get this meeting started. We are already more than half an hour late, and I have another class to get to. Each of us had an assignment that we were supposed to do for this circuit design project. Let’s pull out the preliminary designs and do a side-by-side comparison to see if these circuits we designed will work together.” The sound of papers rustling filled the room as each of the team members pulled their circuit designs from their backpacks. Bill started the discussion since his part of the design was the microprocessor unit; the heart of their project.
Each of the other team members had designed peripheral or input/output devices. It was fairly clear that Bill had put a lot of effort into researching various microprocessors, bringing out reams of data sheets for all the devices he investigated. Over the next 30 minutes, Bill explained the details of why he had chosen the particular model of his design and what some of the tradeoffs were. He gave a summary sheet to each of the other team members with specifications of what input and output signals needed to be from their sections.
“Wow, Bill, that’s a pretty impressive piece of work,” said Tyler. “My design is pretty simple compared to yours. You guys remember that I was supposed to develop the audio input stage and associated electronics to allow the analog signal to be put into the analog to digital converter pin…” Tyler continued to explain his design and mentioned that it would be easy to scale the voltages to whatever level Bill needed on the input A/D pin just by changing resistor values. “This design will probably work Tyler,” said Bill, “but I really disagree with the devices you chose as well as the way that you designed the gain stage. I went ahead and looked up a couple possible other designs, and then I did a simulation to get a slightly better response. You can see that you can get less clipping if you use these new operational amplifiers I
found on the web…”

Next, Sue presented her design, which took a serial bit-stream out of the microprocessor and ran through a series of demultiplexers and latches to drive a variety of input and output devices. Bill, as the team leader, made several changes to her design and asked Sue to incorporate the changes by the next team meeting, on Monday. “OK, Rachel, let’s see your schematic for the power supply,” asked Bill.
“Well, I had a test this week and didn’t get around to doing a lot of simulation, but my friend who took the class before had to do a really similar project. He gave me this design which he used when he took this class. He got an “A” in the class, and he’s really smart. It’s so complicated that I didn’t have a chance to do any simulations or anything, but he swore that it would work well for what we’re trying to do.”
“Well, how do you know it’s going to work if you didn’t do a simulation?” asked Bill. “I know it’s going to work because it did work. Things don’t just stop working if you don’t do a simulation. Besides, this
will save us a whole lot of work.” “Look Rachel, besides this being cheating, every time that you have a design due you turn in something that’s not your own work. I don’t think you’ve done a single simulation, and the reason you got assigned the power supply circuit in the first place was because nobody trusted you to do anything more complicated. You’ve got to start pulling your weight on this team or we’re all going to give you a bad review to lower your grade.”“No, the reason I got assigned the power supply circuit is because you assigned it. Look, just because you’re only taking nine hours a semester and want to get an “A” in this course to preserve your 4.0 doesn’t mean that we all have to work as hard as you do. You’ve got no idea what’s going on in my life, and if you did, you wouldn’t criticize me like that. I don’t even know why I bothered to come to this meeting. Every time I do everybody just busts on me. I’m out of here.” The meeting broke up soon after Rachel left, with Bill stating that he would take over design of the power supply from
Rachel. The next day when Sue and Bill got off the elevator on the way to a test, they heard a familiar voice. “I don’t know why he has to be a dick all the time. It’s not like I’m not working as hard as I can in this class. Besides, the deadlines he sets are really unreasonable; if I had a little bit more time, I would be able to get these circuits done.“
“Yeah, he is kind of a dick. I was pretty pissed off when he told me my circuit design wasn’t good. I went back and simulated his design and it wasn’t really all that much better than the one I turned in. Now I’ve gotta go and ask for samples at all these web site just to get some of the special chips he wants, rather than just buying them here.”
