Task 1: To what extent could or should Deane expect to apply the philosophies and techniques of JIT/Lean to the running of a staircase cell?
Staircases Production Company (SPC) is a small, successful, privately owned timber and building materials company based in a small city in the UK. The company offers a wide variety of timber products, from regular doors, windows and staircases to special products such as non-standard sections or special profiles (i.e. old designs of skirting board). Its products stand out from its main competitors (small joinery businesses) with high levels of quality.

It can be said that processes currently do not follows any flow structure: production is planned without any solid criteria and there is no single flow route for either materials or machinery. This unstructured work floor causes: joinery department job shops are untidy and congested (joiners are working on several part-finished items at once, single pieces of equipment are shared by 10 or more joiners, joiners try to fit in with each other over the use of machinery, etc.) and big allowance of waste and timbers defects are found around the workshop. Despite of this chaos, it has been identified that the specific case of the manufacturing and assembling staircases follows a repeatable process steps (although staircases are different): cutting timber, sanding, machining and tenoning, which makes this process potentially standardised.

However, in order to identify the applicability of Lean principles to the rest of the processes, more information should be provided.
