Analysis of production outcomes included: 1) one year of historical data from customer orders, product costs, commercial and technical information of products with highest impact on Company's
revenue that was obtained from the commercial department this data was useful to select the product models to be analyzed; and 2) cycle times and lead times, which was used to evaluate
production outcomes before and after the intervention; 3) operation,waiting and transportation times on different tasks were measured from the first (wooden frame assembly) until the last
(product expedition) operation of five highly demanded sofa models. Data mentioned in 2) and 3) were collected by two industrial engineers at different times of the day during the first two
weeks of the diagnosis stage. Data collection focused on two courses of action: (i) counting manufacturing parts on all workstations related to sofa manufacturing (enabling a snapshot of
process material accumulation), and (ii) collecting a minimum sample of 10 replications of all times required for process manufacturing in each workstation. Work-in-progress (WIP) data
was collected by counting the number of units waiting for process on each workstation; the number of delayed days was provided by the company personnel responsible for monitoring productive levels.
