SIC (Short Interval Control) is a structured process to regularly review performance data and identify opportunities to improve production effectiveness and efficiency. It involves: 1. Checking performance at short intervals (e.g. daily or every half hour) and making necessary corrections, to prevent small problems from becoming big ones. 2. Controlling process inputs to control outputs and meet goals like increased output, reduced costs and defects. 3. Having team members regularly look back at past performance, plan next actions, and implement plans to continuously improve performance. The benefits of SIC include increased output, effectiveness, improvement speed, and employee engagement through localized focus and data-driven decision making.

2. What is SIC? A little story…
Aiming for a target
• Sailing with the island as the target
• This journey would normally take 4 days

3. Checking performance once the 4 day period has
passed
• Captain checks location after 4 days
• Necessary corrections are made

4. Checking performance after each day
• Captain checks location after each day
• Necessary corrections are made daily

5. Checking performance continuously
• Captain checks location every half an hour
• Necessary corrections are made continuously

6. What are the key goals of SIC?
• Short Interval Control (SIC) is:
 a structured process for identifying and acting on opportunities to improve
the effectiveness and efficiency of production
 a factory-floor process that engages team members to review performance
data on a regular basis to focus their efforts to improve performance

7. By using SIC problems can be identified and
action taken before they become big problems
• Frequent measurement prevents small problems from becoming
big ones.

As in the case of sail boat (see below x-axis), SIC is a tool of reacting timely to avoid problems
becoming big problems…effectively controlling the process inputs in order to avoid problems all
together (next slide)

8. SIC is controlling process X´s (inputs) in order to
control Y’s (output)

Measuring the process metrics (leading) rather than the Ys (lagging) in SIC gives the
opportunity to ACT instead of REACT!!
e.g. number of
customer calls received
e.g. % of calls resolved
on phone
1. Customer
Satisfaction
2. Costs of customer
service

9. The key principles of SIC
1. Review achieved results
2. Plan next activities
3. Implement planned actions

1. Look Back
Review previous losses
Assess previous actions
2. Look Forward
Identify next risks
Decide next actions
3. Implement Actions

10. The key benefits of implementing SIC
• Increased OEE (by focusing on immediate and relevant losses within the
shift)
• Increased effectiveness (by utilizing high-quality data at its source to drive
decision making)
• High speed of improvement (localized focus increases the speed of
improvements)
• Improved employee engagement (teams gain significant control over how
the line is run)
