MoU vs. ARPU

MoU (minutes of use) is a measurement usually in minutes time unit that show how long each user (in average) consumes a product/service in a month. This measurement often used in telecommunication industries or other industries which the product/service consumption is due to time unit (time based pricing) such as : electric/power companies, gas companies, sterilized water companies, etc. The value of MoU can be used as one of performance indicators in some businesses.

Just like MoU, ARPU (Average Revenue Per User) is also one of performance indicators in running one business. This is the measurement usually in currency unit (such as : US $, ID Rp., Poundsterling, etc.) that show how much money each user spend to consume one or more products or services.

Both of MoU and ARPU are indicate the business performance that still could be related to the revenue as its end result. For example : a service company has 3,000 customers with MoU’s value is 120 minutes per month. If the unit price of its service is US $ 1.5 per minute (in average), we can conclude that the monthly revenue of that company is = 3,000 x 120 x 1.5 = US $ 540,000. Assumed if the next coming month the MoU increase to 150 minutes at the constantly unit price. We can easily calculate the revenue based on
the previous month revenue. We just do the simple mathematics operation as follow : 150/120 x 540,000 = US $ 675,000.

Just like MoU, almost the same simple mathematics operation do in ARPU calculation, but a little more simple. For example : if the ARPU of a company is US $ 180 and the number of customers is 3,000 users then the revenue of that month is = 3,000 x 180 = US $ 540,000. Imagine if in the next coming month the value of ARPU increase from US $ 180 to US $ 225. The revenue will be increase also to : 225/180 x 540,000 = US $ 675,000.

In the reverse mathematical operation we can see the differences of these two kinds methods. We can see the differences from its formulated variables. Variables that effect to MoU are totally time usage (for all customers) and number of customers. In other side, ARPU’s variable are : the number of customers and the totally revenue. Either ARPU or MoU is indicate the using of each customer in a month or one periodic time. The only different is it’s the measurement unit. ARPU measured in currency but MoU measured in time unit. They both have the same variable, number of customers. To the increasing of revenue, they both still indicates the same symptomp too. The increasing of ARPU indicates the increasing of revenue, and so does the MoU.

The only question is : when do we use ARPU and when do we use MoU in our analysis ?

ARPU usually use for two or more products consumption combination, and usually the measurement unit also variated too. For example a telecommunication operator that provides voice call (pricing in US $ per minutes), data internet (pricing in US $ per Mbyte), and also mailbox feature (pricing in US $ per month). We should use ARPU method for analysis. For getting the ARPU’s value, we have to calculate the average of invoice of all customers we have. But if in case internet service provider which used flat rate time based charging method, we could use MoU method for analysis in order to evaluate the business performance.

Actually, MoU and ARPU would be better used in complementary one another. In case above, for heterogenic products we usually use ARPU for our analysis. But for further analysis, we could also use MoU (for detailed specific product) such as MoU for International Call, MoU for VOIP, and MoU for local call.
MoU also could be used for analysis which the objective is to know or evaluate the effect of marketing program especially in pricing to the increasing of the usage of every customers (in average).

Please Don’t Buy Headphone before you read this..!!!

Wanna buy headphone or other electronic stuffs but still don’t know about the quality or specification in details ? Or you have limited budget for buy the stuff you want ? You could first read on this website : http://wize.com/ to help you build your consideration. This website contains Consumer research and consumer product reviews.

Each time before we make a decision to buy a product, we must consider about the functions, benefits, prestige, price, features, etc. Many people decide to buy a product after compare it with others, because people want to get the best quality with the cheapest price. Each product has its aspects or factors to fulfill the man needs. They are usually called by : technical parameters that build from the need attributes. For example : the need attributes from shoes are : the comfortably, weight, and the model. These need attributes can be transformed into technical parameters as follows :
- for weight : made by lightly material like : synthetic fiber, celluloids, rubbers, or other elastic materials with
less weight
- for comfortably : inside shoes made by foam and its tread made by abusive materials so could reduce the risk
of to be slipped
- for the model : the pattern of the shoes (colours, shapes) should be match with its users
The same analogy could be used in headphone products.

Headphone is a pair of relatively small loudspeakers (could be separated in single) which could be holding closely to man's ears in its way so he can hear himself the voice clearly from its sources (stereophonic, CD player, MP3 Player, etc) that connected to the headphone. Like other electronic stuffs, if we want to buy, first we ask or see about : the warranty, maximum power handling, the design, and also compatibility. Other considerable factors before buying headphone are : the sound quality (noise filtering capability), the sound type that could be supported (rock, pop, ballad), the sound mode (stereo, etc), frequency response, and the ergonomic (comfort to our ears). These all and maybe more of its are the technical parameters that must be assured before we buy headphone.
In wize.com we can see the comparison of two or more headphone products from different merk (models/vendors). Hereby the wize.com in display (figure 1.) :

From figure 1, we can see the display of this website. This display is a friendly user interface and also complete menu. With this display, make the users/readers easier to find what thing they want to know. This website
completely with the feature like categorized product menu, filtering menu, reviews made menu, and also search button features.

This website is also able to compare the products we want to with 2 easy steps as follows :


As we can see in Figure 2, we just click in the empty boxes which related to the product we want to compare and then click the compare button. So simple, isn't it ?
.
After we do that 2 easy steps, we could see the result (comparison) in tabular like it shown in figure 3 and 4 bellow :


As we can see at those figures, beside the comparison of the related items (technical parameters) there are also the recommendation Level (the suggestion that made by simultaneously people's opinions). In this website is also contain other electronic stuffs.
Others that we can see in this website are as follows :
- Blog that contain the article, new, and writing of any products (we can see in : http://blog.wize.com/).
- Computers and Office Products (we can browse at : http://wize.com/computers-and-office).
- Kids and Baby products (we can explore in : http://wize.com/kids-and-baby).
- more over

Hopefully, this writing could help readers find the right headphone or other products as you need.
