Tracing patterns for business requirements in big complex products

We have only base rules of software production process in Kaspersky Lab. Each team can decide how to manage scope of their product, component or service. There are some base useful types of traces are created in last two years. These types of traces can be useful for PM to manage project scope, and can help system owners to manage their requirements for some products. We described these variants, developed instrumental support for it and can reuse it to achive of project goals in more efficient way. I will describe these patterns and will show some examples.
