In today’s highly competitive market, businesses aim to launch new products faster and with better quality. Unfortunately, network designers often have to focus on low-level details, rather than business needs during the development process. Sometimes, the design stage exceeds its original delivery date and tests are mostly dropped, as there is not enough time to finish them properly. This inadequate testing could result in revenue loss. It’s not uncommon that an operation team has to modify a design to make it work in the “real world” – increasing complexity and therefore cost.
