do you still roll up your VSM and hope that the glue won`t get dry before the job is finished

Working with value stream mapping should be an ongoing activity that never rest from challenging your productivity indicators. The quantitative approach that VSM provide will support the qualitative discussion when evaluating improvements. Going into VSM as a project will fail, you may have some short term results but long term continuous improvements that really affect productivity will not be a reality. To be able to establish a new standard there is a need for an easy to use tool that don´t stop you from keeping the maps up-dated. And if the tool saves time and also supports teamwork, so everyone have the opportunity to participate and contribute! Than you have the right prerequisites to achieve more!
