Beyond the Thin Client
Why a Smart Client ERP Solution May Be a Smarter Choice




       Executive Summary
       Over the last decade, browser-based “thin
       client” applications have come to dominate
       the enterprise application space due to
       their ease of deployment, updating, and
       administration. However, while thin client
       applications address IT deployment issues,
       they typically fail to meet end-user expectations in terms of robustness, performance,
       and usability. Given that user adoption is critical to the success of enterprise resource
       planning (ERP) projects, today's organizations must place high importance on the
       user experience in selecting an ERP solution. So what are your alternatives if your
       organization wants an ERP application that is not only easy to deploy and access,
       but also creates a rich user experience?

       This white paper compares and contrasts the two primary alternatives to thin clients—
       enhanced thin clients that use technologies such as ActiveX, AJAX, and ASP.NET and
       the new generation of “smart clients”—and examines the differentiating characteristics
       that could impact your ERP implementation. It concludes that a smart client ERP
       application is a better solution for most enterprise users, based on performance,
       usability, total cost of ownership, security, and ease of integration.
Introduction                                                     Finding a Better Alternative

              expectations in terms of robustness, performance, and

              responsive applications that enable them to perform
              their daily work in a flexible and efficient manner that is
              not always possible given the inherent limitations of thin
              clients. Add these factors together and it becomes clear
              that a new category of client application is required to
              meet expanding business-user needs.

              Given that user adoption is critical to the success of
              enterprise resource planning (ERP) projects, today's
              organizations must place high importance on the user

              that is not only easy to deploy and access, but also

              means that .NET controls that you may have developed
              for another application or purpose can easily be dropped
              onto a smart client form and be used and re-used without
              re-programming. These .NET controls can provide integra-
              tion of functionality or features from your other enterprise
              applications through the use of Web Services, providing a
              “one-stop shop” for end users, who save time by working
              within a single application.

Microsoft has spent millions of dollars developing
and embracing smart client technology, and this new
technology has been welcomed enthusiastically by
developer communities. With the smart client, Microsoft
has addressed the shortcomings of traditional Windows
clients, including:
•	 Difficulty deploying and updating
•	 Heavy DLL administration
•	 Lack of access from the Internet
•	 Poor performance
•	 Lack of integration capabilities
•	 The limited capabilities of older desktops

Wp Beyond The Thin Client On Erp

  • 1. W H I T E P A P E R Beyond the Thin Client Why a Smart Client ERP Solution May Be a Smarter Choice Executive Summary Over the last decade, browser-based “thin client” applications have come to dominate the enterprise application space due to their ease of deployment, updating, and administration. However, while thin client applications address IT deployment issues, they typically fail to meet end-user expectations in terms of robustness, performance, and usability. Given that user adoption is critical to the success of enterprise resource planning (ERP) projects, today's organizations must place high importance on the user experience in selecting an ERP solution. So what are your alternatives if your organization wants an ERP application that is not only easy to deploy and access, but also creates a rich user experience? This white paper compares and contrasts the two primary alternatives to thin clients— enhanced thin clients that use technologies such as ActiveX, AJAX, and ASP.NET and the new generation of “smart clients”—and examines the differentiating characteristics that could impact your ERP implementation. It concludes that a smart client ERP application is a better solution for most enterprise users, based on performance, usability, total cost of ownership, security, and ease of integration.

Introduction Finding a Better Alternative Today’s IT organizations are under pressure to deliver IT professionals have faced a major challenge in realizing robust, usable, and efficient business applications that the benefits older Windows-based applications offered meet the increasing expectations of business users and over thin clients, without adding the complexities and the executives who need contextual access to business high management costs that were associated with these data and tools to help them stay competitive. These traditional “rich clients.” To address the shortcomings of applications must also be flexible enough to enable the both thin clients and the previous generation of Windows company to adapt to ever-changing market conditions rich (client/server–based) clients, companies have been and demands. looking at two main alternatives: Over the last decade, browser- based “thin client” applications • Thin clients that have been enhanced with the use of Users now expect faster and more technologies such as ActiveX, AJAX, and ASP.NET to have come to dominate responsive applications that enable mimic a richer user interface (hereafter referred to as the enterprise application them to perform their daily work in a space due to their ease of "enhanced thin clients") flexible and efficient manner that is deployment, updating, and • Smart clients, which promise to take full advantage of not always possible with thin client administration. the rich client model, providing a rich user experience, applications while at the same time reaping the benefits of thin However, while thin client clients applications address IT deployment issues, they typically fail to meet end-user expectations in terms of robustness, performance, and usability. Users now expect faster and more responsive applications that enable them to perform their daily work in a flexible and efficient manner that is not always possible given the inherent limitations of thin clients. Add these factors together and it becomes clear that a new category of client application is required to meet expanding business-user needs. Given that user adoption is critical to the success of enterprise resource planning (ERP) projects, today's organizations must place high importance on the user experience in selecting an ERP solution. So what are your alternatives if your organization wants an ERP application that is not only easy to deploy and access, but also Since both of these clients are superior to pure thin creates a rich user experience? clients, this white paper will focus not on thin clients but This white paper compares and contrasts the two primary on the differences between these two main alternatives. alternatives to thin clients—enhanced thin clients that use Enhanced thin clients typically use AJAX, ActiveX, or ASP. technologies such as ActiveX, AJAX, and ASP.NET and NET technologies to expand the capabilities of traditional the new generation of “smart clients”—and examines the thin clients. These technologies allow developers to create differentiating characteristics that could impact your ERP more dynamic, responsive applications for web delivery implementation. while retaining advantages such as the ability to leverage the internet and provide easy remote access to data. A smart client is a .NET technology for building rich internet applications that provide users with a highly interactive user interface. Smart clients aim to provide “the best of both worlds” and bridge the gap between web and desktop applications by adding the intelligence to manage data and connectivity to produce a superior user experience. While smart clients provide the benefits of a rich client model with thin client manageability, they also provide more flexibility and capabilities than traditional rich client applications.
