This plan was originated by James Rowan of David Rowan and Sons of Glasgow, Scotland. The system is similar to Halsey plan except for a different method of computation of bonus.

Here the bonus is calculated as a proportion of the wages of time taken which the time saved bears to the standard time. The main features of Rowan plan are:

(i) There is a guaranteed day-wage for actual time taken on the basis of time rate.

(ii) Bonus is paid for the time saved.

ADVERTISEMENTS:

(iii) Bonus is based on that proportion of the time wages which the time saved bears to the standard time.

Total earnings of a worker will be:

(Time taken x Time rate) + (Time taken x Time rate x)

The advantages and disadvantages of Rowan plan are as follows: Advantages

ADVERTISEMENTS:

(i) The plan assures a minimum hourly rate.

(ii) The quality of output is protected since the bonus declines after the worker has reached a given level of efficiency.

(iii) Labour cost per unit and fixed overhead cost per unit are reduced with increase in production.

Disadvantages

ADVERTISEMENTS:

(i) The plan is not easily followed by most of the workers.

(ii) Efficiency beyond certain point is not rewarded. It fails to distinguish between a very efficient worker and a worker with a little more than average efficiency.

(iii) Since the employer gets a share of the wages of the time saved, the workers do not get the full benefit of their efforts.
