Using Protoforge for SEDSAT-2
We will use Protoforge to store and manage our requirements and vote on them as a group. This is how we will make decisions on the system design even though we are dispersed across the globe and can not communicate regularly and directly with each other.
If you are not familiar with requirements already check out the Wikipedia requirement page. By using Protoforge it will not be as important to know or study how Systems Engineers currently organize requirements (there are as many ways to do it as there are systems engineers). Protoforge simplifies things by keeping all the requirements in one hierarchical tree instead of many different requirement specifications.
The Getting Started guide is a good place to start learning about Protoforge and the Requirement Help document has some more about requirements. Don't forget to join the SEDSat-2 project after you have registered a user name at the Protoforge website.
Make sure to review the Protoforge Requirement Process to get an understanding of how the process works.
You can suggest a requirement for the SEDSat-2 project any time you want. Even if you are just bringing up the idea for discussion. This is a good way to learn about different possibilities for designing a satellite. Suggest a requirement and get feedback about it on Protoforge. If you decide that the requirement really should be a requirement that gets included in the baselined design, then finalize it and have your team members vote on whether or not the requirement becomes a part of the baselined system definition.
