iPad 34% Faster Than Workstation or Laptop, For Key ERP Functions

We test the tablet form factor in parts of the enterprise where one might expect it to be faster..and it is!

Up to 40% of corporate users could improve productivity

Used new Enterprise iPad Toolkit from iOptimal

In which parts of the enterprise does the iPad offer the best productivity gains? We set out to find the answer to that question, and the answer is: 20%, 40%, and 34%.

We chose a set of five common data entry screens from a corporate ERP suite – Financials, MRP, CRM, and Human Resources – from vendors such as SAP, Oracle, Lawson, and Salesforce.com. These screens were chosen as a cross-section representing (as best as possible) the thousands upon thousands of legacy database applications used in organizations across the world.

We built “iPad optimized” versions of those screens, which exactly duplicated the data entry functions in the standard Windows/keyboard versions. To build the iPad version we used the new iPad-enterprise prototyping tool just released by our partner firm iOptimal.

We chose these five functions carefully, to represent what we call the “40/20 rule." 40% of corporate users – generally managers, supervisors, and engineers – use only 20% of the ERP functions. By a happy coincidence, those 40% of users – our target audience – are also the ones that most likely to use a tablet, since they are generally people who “move around the office a lot” and have difficulties using laptops and workstations. Also by happy coincidence, the 20% of functions needed by these people are functions which don’t require large amounts of keyboard use, thus are well-suited for mobile tablets.

Converting that 20% subset of of ERP functions to the iPad should create significant time savings and a lot of happy users (and happy IT managers as well, since happy users become enthusiastic supporters for IT departments).

The Results

For our five representative tests, we had people perform the correct functions as fast as possible. We timed them by watching keystrokes and time motion study (using a stopwatch). On average these functions were 34% faster to perform on the iPad, for identical data entered, compared to the laptop or workstation.

Why Faster?

Quite simply, the screens typically used by supervisors and engineer lend themselves well to touchscreen interface. Using iPad user interface standards concepts, we were able to greatly reduce clutter on the screens, use finger gestures to quickly select options (more quiickly and intuitively than the mouse), eliminate almost all keystroke entry, and use location-based optimization to auto-fill and rearrange some fields.

The net result was, faster use.

Easier To Use

In addition, the screens were dramatically more enjoyable to use. Old style ERP is often quite crowded and complex to work with, with multiple layers of menu and complex coding structures; we took the opportunity to clean it up.

Caveats

• Some people might claim that the windows/laptop screens, if they were re-designed and improved, would show a lot of improvement as well. This is likely true. But the fact is, most ERP software isn’t being re-designed. So if the iPad serves as a catalyst to force us to clean up our designs, well, that’s a valid success.


• Note also that this 34% number does not include the fact that users can “carry the iPad everywhere” and would no longer need to walk back to their desks, re-log-in, or deal with charging a laptop. For some users, the iPad is faster simply because it can be carried all day long and eliminates more of the paper forms which still plague many organizations. If this mobility improvement was taken into account, this would add even more to the iPad’s speed advantage for this test. We are working to get an estimate of this number.


• Let’s reiterate that the iPad is unlikely to be faster (and might be slower) for functions that require heavy data entry or typing. For these functions, a keyboard is an advantage, and data-entry users who sit at their desks during the day won’t get much advantage from the mobility of a tablet.


• Finally we should note that these are preliminary results. We'd like to conduct this test again under more rigorous conditions. Nevertheless it does support what many users recognize intuitively: that a touch tablet with a highly tuned interface can increase the efficiency of business users.

Added note (9/14): People say we should do this test again, with a bigger sample set and with more "disinterested observers." Maybe even a media extravaganza! Great idea.
