MAKING PRODUCTIVITY VISIBLE TO EVERYONE
What is SIS®
SIS® stands for short interval schedule, which is a 3 day look ahead utilized by the field labor. Each day,
the foreman distribute a 3-day look ahead schedule for their entire crew, including themselves if they are in a
working foreman role. Why do we do a 3 day and not a 5 or 10 day look ahead? Our experience shows that 3 days is
about the furthest out a foreman can see realistic work. We know that construction schedules change frequently,
What does SIS® do?
SIS® identifies hindrances to the field that are causing the field workers to not be able to install the most
effective and productive way (e.g., trade stacking, trade interference, lack of materials, lack of tools, broken
tools, etc). The 3-day look ahead also helps the foreman to plan for material ordering and procurement as well as
appropriate manpower for the coming weeks.
Helps the foreman to keep a 3 day look ahead to ensure they have the proper materials ordered and proper
manpower to do the tasks.
What does SIS® measure?
SIS® measures the number of hours not worked as scheduled as well as the obstacles that caused these hours to
not be worked as scheduled. When a worker is scheduled to complete a task and, at the end of the day, it did not
get completed, they are asked to identify the reason that the task was not completed from a set of primary reason
codes. These codes are specific to each job and are created entirely by the foreman and his crew to match the
obstacles that they think may affect their productivity.
Why are we doing SIS®?
We are doing SIS® to become more effective installers and eliminate waste from all aspects of installation.
SIS® identifies hindrances to our productivity right away while there is still time to react and do something
about it. SIS® will help us compete with non-union companies that have lower composite rates. SIS® will help us
look at our own day to day procedures within VECA and see what things we can streamline and do better to make the
installation in the field more effective and eliminate the wasted time. (Material Handling/Movement, Document
Control & Posting Changes on Field Drawings, Tool Issues, Material Issues, etc.)
