As tablet devices become used more widely for business transactions, it can be argued that the interactive PDF form has now had its day, and will be replaced by device-friendly html or on-device apps. In this update I consider what the future may be for the PDF form.
Firstly, mobile is here. It might not have disseminated down to lots of companies or processes, but the tablet is going to be a key business device, and it is absolutely essential for user technologies to work on these devices. Right now that rules out PDF, as the mobile version of Adobe Reader does not support user interaction. And in the future it rules out PDF too. Adobe are not suggesting that they will ever support interactive PDF on mobile devices, and even if they did, the devices already have built-in PDF viewers, and so there is little incentive for users to install the app. There is little chance of an Adobe Reader app ever reaching the saturation they managed in the desktop world.
The clear and (only) alternative is HTML5. For this, the only app required is the browser that is supplied with the device, and so HTML-based forms are easy for users to adopt.
If we look at the evidence from SAP:
- HR Renewal. For HCM Processes and Forms, SAP have introduced webdynpro forms to replace PDF forms
- Adobe Document Services. SAP and Adobe have announced that they are working on extending ADS to render HTML5 in addition to PDF
- SAPUI5. SAP now has an HTML5 focus for their browser-based user interfaces.
In the past we had many reasons for advocating PDF as the best technology for interactive forms, but increasingly those reasons are less relevant. For example:
- Paper-like interface. In the past, a huge selling point was that the PDF could look just like the paper form it was replacing. However, users are now very familiar with mobile and web-based tools.
- Same on any screen. A PDF form looks exactly the same on any screen because Adobe Reader is installed on the machine. However, our expectation is now that the interface should dynamically change to make best use of the device screen.
- Same on any printer. A PDF form looks exactly the same when printed, regardless of the printer. However, we are printing fewer and fewer forms.
- Digital signatures. A PDF form can capture a digital signature. However, practically, either the form is being filled by an employee, who can authenticate by Single Sign On, or by a business partner, who is not likely to have/use a digital signature.
So, many of the old selling points for PDF have lost strength over the last 5 years. Also, the entire look and feel of many PDF forms now appears a little old fashioned. Users expect fewer fields, controls like sliders and controls that work with touch-screen ‘gestures’.
Does is this the start of the end for PDF? Well, perhaps. It’s certainly a pretty damning indictment. Perhaps the PDF form will become increasingly more of a point solution.
So why are we not abandoning it completely? Let’s look at where PDF works well:
- Development Effort. We find PDF forms easier to build that the HTML equivalent, because HTML looks different on different browsers, and because different browsers support different HTML5 tags.
- Off-line forms. Put simply, PDF forms can go off-line, and HTML forms can’t. At some stage this might be possible, but an app will be required on each client machine. So for forms that go across the firewall to business partners, the PDF form capability cannot yet be replicated in HTML.
- Save locally. In many form processes it is very powerful to be able to save the form locally, where it can be viewed again without connection to a server.
- Archive. Since the PDF is a complete document, it lends itself well to being archived and subsequently retrieved from the archive intact.
Firstly, I can see PDF remaining an important option for highly regulated industries that have audit and compliance requirements. And also I can see many requirements, such as account applications, employment applications, new supplier forms that will continue to be best served by a PDF form approach.
So let’s not sound the death knell just yet.
