Manufacturing Case Study

Client Profile

Large food manufacturer installed a robust Management Operating System (MOS) years ago, improving OEE significantly. Since then, usage had waned, and it was no longer being used to effectively manage the operation.

Solutions

  • Consultants partnered with supervisors, working side by side. Consultants provided 24/7 coverage on site, shadowing supervisor the entire time.
  • Focus was centered on floor, operator performance-based interaction, confrontation skills, and accountability.
  • Supervisors were evaluated daily and graded on 29 elements. One-on-one reviews were conducted on a weekly basis to discuss highlighted opportunities and improvement.

Challenge

Supervisory Shift Transition

  • Supervisors often inherited a plant with poor housekeeping with expected work not completed
  • Transfer of information between shifts was spotty, often resulting in substantial lost supervisory and production time because of not knowing current conditions

Shift Change

  • Machine ​downtime at shift change was extensive
  • Protracted start up / scheduling meetings prevented operators from getting out on the floor by the start of the shift
  • Operators would frequently leave their stations up to 20 minutes before the end of the shift

Unclear Supervisory Roles

  • With 2 supervisors per shift, task delineation was unclear
  • In some cases, one supervisor would play a purely administrative role with little to no time on the floor

Little Effective Interaction with Operators

  • Supervisor’s time on the floor was mostly equipment focused
  • If there were interactions with operators, discussions were casual, and performance was not discussed

Lack of Accountability

  • Blatant violations of PPE and GMP policies were not confronted
  • Actions taken by operators that resulted in significant loss of time or product were routinely “explained away” or ignored, not addressed

Approach

Standardize Transition Process

  • Design and install Standardized Pass Down process with agenda
  • Implement structured building walks with oncoming supervisor “accepting” current building conditions

Improve Startup Meetings

  • Pre-post job assignments, so operators do not have option to choose jobs during meeting to shorten start-up meeting
  • Ensure incoming operators relieve outgoing operators at their workstation

  • Ensure incoming operators relieve outgoing operators at their workstation

Leader Standard Work

  • Clearly define and agree to what a typical day in the life of a supervisor should look like including floor tours, process checks, and meetings
  • Require supervisory presence on floor to assure operators remain at their stations and with machines running

Performance Based Supervisor Floor Tours

  • Formalize floor tours to include online checklists for supervisory review of operating condition and entry of settings and parameters
  • Incorporate reviewing current/shift performance with operators as well as validation of downtime reporting, Quality and Metal Detection tests

On Floor Coaching

  • Coach supervisors by working side by side with a supervisor
  • Focus on discussing situational responses and assuring accountability is administered where warranted

Results

Improved OEE

  • OEE increased from 52% to 63%

Regimented Shift Transition Process

  • Housekeeping standards have dramatically improved
  • Supervisors come in prepared and are no longer “surprised” by conditions on the floor

Effective, Efficient Shift Change

  • Lost time at shift change has been virtually eliminated
  • Machines continue running through shift change with operators present

Clear Understanding of Roles

  • All supervisors balance administrative vs floor time much better. No supervisors are exclusively focused on administrative tasks anymore.
  • Supervisors are averaging about 70% of time on the floor
  • Daily supervisor routines are much more coordinated and habitual

Constructive Supervisor and Operator interactions

  • Discussions with operators are collaborative and occur frequently throughout the shift/day
  • The focus is on performance and removing barriers to get back on track

Consistent Application of Accountability and Discipline

  • Preliminary discussions and agreement with union allowed a significant increase in accountability
  • When appropriate, disciplinary actions were taken, without an increase in grievances

Performance improvements directly translated into over $1MM in annualized cost savings based solely on labor reductions.
