Iterate Instead of Working Towards Deadlines
Many Agile projects still stick to working towards deadlines instead of iterating and building product increments. When working towards a deadline, building feature after feature per iteration, the benefits that one would normally have with an incremental way of working, such as learning about users, market, technology, and architecture are lost. The risk of waste is taken for granted in that case. Nevertheless the agile manifesto is violated on several points such as simplicity or delivering valuable software to users.
