So I have finally finished up my timeline... I made a schedule for both the remainder of this semester and next semester, when I will be presenting my capstone.
I found that the remaining of this semester's timeline was much easier to write then the next semester one... perhaps it's because I have a solid grasp on what's already happening this semester and it's underway, while next semester is still uncertain and I had to work more to plan it out. I did also feel like I might be rushing at the end, mainly when I realized how much I still have to do. It's making me uncomfortable... but I'm glad I caught it now so I can prepare and adjust for it in the future, and change it in my schedule.
I found it easiest to break up my "parts" by ...well... parts. It seems to be the most natural way, so why not. Right now, in a separate independent study I'm doing environmental art for my exploration scenes and background art. I have other sections for sound, animation, programming, testing, printing, etc... and I would also sometimes pair things together, like sound and the animatic, since I've found I can work better on something when I have a "getaway" from it, so I can work on 2 different things and not feel stifled by one.
I also have a large buffer zone at the end of about a month to compensate for any extra testing or work I might need to do. I also leave a long amount of time for alpha and beta testing to make sure everything works.
I have my work cut out for me, but as long as I stay on top of it, and because I have the extra buffer zones, I feel like I can finish everything on time.
