Variance Analysis
Interpretation and interrelationship of variances.
To investigate or not to investigate before management decides whether to investigate a particular variance, there are a range of factors that ought to be considered.
o Materiality. Variance calculator in a single period are bound to occur and are unlikely to be significant. Obtaining and'explanation'is likely to be time-consuming and irritating in the manager concerned. The explanation will offer be'chance'which is not, in any case, particularly helpful. For such variations further investigation is not worthwhile.
o Controllable. Controllable must also influence the decision whether to investigate further. When there is general global price increase in the price increase in the price of an important raw material there is not anything that can be done internally to control the effect of this. Uncontrollable
o Variance treads. If, say, an efficiency variance is $ 1,000 adverse in month 1, the obvious conclusion is that the procedure is out of control and that corrective action must be taken. This may be right but what if the same variance is $1,000 adverse each month? The trend indicates that the process is in control and the standard has been erroneously set. Suppose, however, that the same variance is consistently $1,000 advise for each of the first six months of the year but that manufacturing has steadily fallen form 100 units per month 1 to 2 65 units by month6.The variance trend in absolute terms is constant, but relative to the amount of units generated, efficacy has tot steadily worse.
Management signals from variances trend information.
Variance analysis is a mend of assessing performance, but it is only a method of signaling to management areas of potential weakness where management action may be necessary. It doesn't supply a ready-made diagnosis of faults, nor does it supply management with a reedy made indication of what action has to be taken. It merely highlights things for potential investigation.
Individual variances shouldn't be looked at in isolation. As an obvious example, favorable sales price variance is likely to be accompanied by an adverse sales volume variance: the increase in price has caused a fall in demand. We know in addition that pair of variances must be inspected for a variety of consecutive periods if their full significance is to be appreciated.
Here are some of the signals that may be extracted form variance fashion information,
O Materials price variances may be favorable for a few months, then change to adverse variances in the next few months and so on. This may indicate that process are seasonal and perhaps stock could be built it up cheap seasons.
O Regular, perhaps fairly modest, increase in adverse rice variances usually indicates the functioning of general inflation. If desired allowance can be made for general inflation when flexing the budget.
O Rapidly large increases in adverse price variances may suggest a scudded scarcity of a resource.
O Gradually improving labour efficiency variances may signal the existences of a learning curve, or the success of a productivity bonus scheme. In either case chances must be sought to encourage the tendency.
O Worsening trends in machine running expenses may show up that equipment is deteriorating and will need repair or even replacement.
Interrelationships between variances
Quite possible, individual variances shouldn't be looked at in isolation. One variance may be inter-related together with another, and much of it might have occurred only because the other, inter-related variance occurred also. When tow varies is interdependent (interrelated) one will usually be adverse and the other one favorable.
O Material price and usage-if cheaper materials are purchased to be able to obtain a favorable price variance, materials wastage might be higher and an adverse usage variance may occur. When the cheaper material is more difficult to handle, there could be an adverse labour efficiency variance too. If more expensive material is purchased, however the price variance is likely to be adverse but the usage variance may favorable.
