Design case: Tata’s Nano

Tata Motors has launched the cheapest car in the world with the purpose of providing a car with the minimum standards and affordable for many Indians.

Strategy:

It is an extreme case of design reduced to what is strictly essential; we have seen this in notebooks and other electronics already. Having a look at the features it includes, helps us picture the scene:

On the cheapest version the driver’s seat is the only seat which can be adjusted.

There is no power steering and various “luxuries”, such as air conditioning, fog lamps, front power windows or central locking are only available on pricier models. I don’t know about you, but I could do without  front power windows if that would mean reducing the price of the car. For us, the ones that see the car as a big tool that helps us get from A to B, there is a big difference in the value of real functionality, such as power steering, and commodities that allow you to get lazy such as central locking.

It is a nice example of targeted design: rather than competing directly with the next cheapest car, it aims to substitute scooters and small motorbikes, with a price of Rs. 100,000 (around $2000).

To meet all economical and quality requirements a good bit of innovation has been required. It is estimated that at least 35 patents associated with the vehicle have been registered.

Environmental issues:

This is one of hottest aspects of the Nano; on the one hand it is a car and it pumps out twice the CO2 as a scooter. On the other hand it has a 4-stroke engine and a crude catalytic converter which appears to reduce most pollutants by about 80 percent and which scooters lack of.

It also meets Euro-IV and Bharat Stage-III compliant, European emissions standards.

From my point of view, the problem here is not the Nano. Of course it will have a terrible effect on the already highly polluted cities in India, when the 50 million orders already placed for the car are delivered. But this is just the consequence of a barely existing public transport system in cities.

Indian cities are extensive and saturated with traffic, and on top of it most of the families can’t afford their own vehicle. This is cry for a well planed and far reaching public transport. If there are no measures taking in this direction, India will probably soon assume the car centred transport system, similar to the US, and then it will be really difficult to change things.

Mockups Tool Review

Mockups are sketches representing key GUI features. They are specially used early in the design process to order ideas and to get feedback from the user. Traditionally, they were made of cardboard but now there are several software tools to make the process of creating them much faster. In this article I would like to tell you my experience with Balsamiq Mockups, a tool we used at Design vs Art for our last project.

Note: following our request, Balsamiq sent us an activation key to fully test the product.

 

The big thing

After trying several mockups tools, what it got my immediate attention was that the elements bar is located on the top of the window. Elements like buttons, containers, text and others for the iPhone are represented by huge icons that users only have to select and place on the mockup to make use of them. It doesn’t seem to be an important feature but it actually is, I have problems with other tools at the moment of looking for elements.

The "sketchy" look is great

I like the sketchy look so much because it turns attention away from details and allows users and testers to focus on the content and functionality. With this feature everybody understands that the presented "web" is just a test (what it also encourages users to criticize without fear).

A few problems found

I have found two main negative issues:

- The property inspector is a floating bar appearing and disappearing as the user clicks on an element. I wish it was just a normal bar that is there without moving around, the fact that it is "blinking" all the time distracts users when they working. 

- It is no possible to link mockups among them. This is a key feature that many other tools offer and Balsamiq should too. The company is already working on this (as I read on forums). 

 

Conclusion

We are probably going to keep on using Balsamiq Mockups and I would totally recommend the tool but linking mockups is a feature that Balsamiq should offer to keep next versions competitive.
