1.2 Problem Statement
The research problem formulated in the thesis originates from practical problem that company faced which are difficulty in production scheduling activity
and instability of MPS metric performance. Preliminary discussion with company in the project formulation phase
revealed that there are some variations in production schedule execution, where
production team using different work method, production sequencing, manpower
arrangement, resulting different output of product in each shift although available time is the same. Instability and inaccurate information of production output per line
per shift made difficulty to create accurate production schedule and in the end will create instability of MPS metric performance.
Some of those problems drove to another basic question “what can we do to improve this production scheduling activity and MPS metric performance?” Of
course, the basic answer given would be “eliminate those variations and make standardization to the work in the shop floor”. The decision made was to visualize
and analyze the process flow on production shop floor and then propose model of improvement using lean manufacturing methodology especially mapping tools which
had proven as powerful tool to identify wastes, improve and standardize work flow.
1.3 Research Objectives
The objective of this research is to improve production scheduling activity and MPS metric performance by building model of basic stability in production shop

floor. Model of basic stability in this thesis will be represented as Standard Operations Sheet SOS that will help the company to standardize their production
activity and eliminates most of wastes by using Value Stream Mapping Methodology. Value Stream Mapping is one of Lean tools that will help researcher to define the
current state and to develop the future state of the process flow, and finally develop standard work that applicable align with future state.
