Business Processes mirrors the organisations culture. Long winding and complex manual processes usually reflects a business culture which lacks creativity - if it is not broke then no fix is required. New processes then follow the same template.
Without a change or even a modification in culture poor process will persist. A company may hire an external consultant to provide advice on streamlining processes. In the short to medium term time-frame, these new processes may be maintained. In the long-term as the business evolves and new business requirements need to be satisfied, the company culture will ultimately drive the evolution of new processes. Old ways of doing things will gradually morph the new processes back to the old or a hybrid variant.
