Sisyphus will have a Snowball rolling effect similar  Newtons 3rd law 
For every improvement made through CI  there is an limiting point where it topple back in terms of Change management or Complete overhaul of Technology or process methodology include but not limited to Change of people all together.
The tendency to stop this process is doing PDCA approach where during each phase we should not come down by keeping a wedge kind of mechanism of bench-marking.
 
Approach of "Continuous" to be made to "Continual improvement" where there is a provision to standardized the achieved result at each stage and making that as a benchmark for the next process.
 
Similarly usage of Horizontal deployment methodology  will also leads to lesser work for doing similar improvement in other processes. (parallel process)(not re-inventing wheel).
 
The Tipping point effect of changeover from Sisyphus to Snowball should be monitored and Controls to be standardized using risk elimination methodology by "Mistake proofing". similarly use of Corrective and preventive & predictive mechanism will help us to overcome the Sisyphus effect. 
 
There are additional ways of analysis and overcoming as FMEA and Re-FMEA after implemented solutions reduces the effect and "Lesson learnt" activity will help to reduce the effect of Sisyphus.
