Case study · Filtration
Shorter training, one standard on every shift.
MANN+HUMMEL uses REWO video instructions to train operators, standardise SMED changeovers and keep instructions on shop-floor monitors. Training time for certain operational skills fell by up to 50%, and changeover inefficiency dropped by 15%.

Standalone — shop-floor monitors
MANN+HUMMEL is a global filtration specialist, developing filtration and separation solutions for mobility, air, water and industry across two business units: Transportation and Life Sciences & Environment. Family-owned since 1941, it operates over 80 sites worldwide.
The challenge
The same job, done differently every shift.
Across plants and shifts, the same work was being learned and done in different ways.
Long training on some skills
Certain operational skills took up to six hours to train.
Different data on every shift
Operators entered downtime and OEE data differently across three shifts, so data quality varied.
Inefficient changeovers
Paper-based guidance left inefficiencies in SMED changeover steps.
Instructions off the floor
The push for digitalisation needed instructions operators could reach throughout their shift.
The solution
Video where the work happens.
MANN+HUMMEL used REWO for training, changeovers and everyday reference at the workstation.
One video standard for every shift
Operators across all three shifts were trained on the same video instructions, which stay available for reference.
Standardised changeover videos
SMED changeover steps were captured as standard video work instructions.
Instructions on loop at the line
REWO runs in autoloop on dedicated monitors and shared workplaces, reachable throughout the shift.
Built into a company academy
REWO was integrated into an internal sustainability academy that educates employees on sustainable practices.
The results
Faster training, fewer variations.
Up to 50%
Less training time on certain operational skills (6 h → 3 h)
15%
Less changeover inefficiency
70%+
Positive feedback on the academy pilot
3 shifts
Trained to one standard for data entry
Training time halved on some skills
Training for certain operational skills went from six hours to a maximum of three, saving non-productive time.
Better data quality
A consistent approach to downtime and OEE entry across shifts improved the quality of the data.
Smoother changeovers
Standardised video instructions reduced changeover inefficiency by 15%, with clearer guidance than paper.
Training that scales
The academy pilot received over 70% positive feedback from employees.
Bottom line
One way of working, across plants and shifts.
At MANN+HUMMEL, REWO improved training efficiency and standardised processes across plants and shifts. Video made knowledge transfer easier for operators — on the line, during changeovers and in company-wide education.
