Case Studies

Case studies

Over the decades, many case studies have been conducted using ErgoSuite and it’s predecessor versions with the results being consistently delivered.  We’ve included several of them here as emblematic of the solid effects of Office Ergonomics in the computerized workplace:

Case Study – 363,326,775 Observations

Yet another extensive research project is presented, specifically analyzing 363,326,775 keystrokes and mousing seconds belonging to a large population of employees. Here is live data underlying an ErgoSuite chart analyzing seven month’s usage of ErgoSuite’s Employee Tools by a large population including a diverse spectrum of job functions:

Above, we’re looking at an actual ErgoSuite Enterprise chart where we’ve chosen to view Trend Lines (Least Squares Linear Regression) which model live underlying data. Used throughout data analysis and in mathematics, these lines represent the actual underlying data’s movement over time. Of course, raw data is never as smooth as the trend lines because it ebbs and flows over time traversing seasonality such as reduced activity during holidays, however, the trend is clear and reliable. Linear regression is an invaluable tool widely used for modeling trends from complex data sets. Within this graphical report:

  • ErgoSuite is modeling live data specifically examining (1) Keystrokes, (2) Hours Keying, (3) Employee Fatigue, (4) Coaching Cues from ErgoSuite’s ErgoCoach and (5) Cue Compliance which is a measure of an employee’s adherence with coaching cues supporting an organizational best practice.
  • These coaching cues are only required when an employee’s “recovery time as a function of duration and repetition” is inadequate (high risk).
  • Each metric in the chart is indexed to its initial value, for comparability, showing its trend (growth) over the period. For example, seeing Cue Compliance grow from an index of 100 to 101 simply means its growth has been 1% from its initial monthly value and does not imply that compliance is above 100%.
  • In fact, the overall Cue Compliance for this specific population of employees was solidly within the 90%-100% range throughout the period.
  • The average number of observations ‘per employee’ underlying ‘each’ trend line is more than 84,000 over the seven month period.
  • This employee population spans the spectrum of low, medium and higher computer-usage.
  • In addition, we know from other collected live data analyses that when employees develop new good ergonomic behaviors at work, these learned behaviors carry on after work when using the computer at home.
