With increased competition, deregulation, globalization, and mergers & acquisition activity, enterprise software buyers realize that product architecture plays a key role in how quickly vendors can implement, maintain, expand/customize, and integrate their products. Many in the enterprise applications vendors' community recognize that these are unmet realities and are attempting to offer solutions that will deal with them. While it is not practical to look at every strategy and every vendor's nuance, this note looks at some important examples representing distinct strategic approaches.
One of this note summarized the recent TEC series "What's Wrong
With Application Software" and analyzed the vendor strategy of Evolution to
address the problems cited.
Two discussed and analyzed the vendor strategy of a New Framework.
vendors have even decided to attempt using a brand new approach to software
to solve the above issues. One vendor in case would be Ramco Systems
who has used an internally developed Model Based Architecture to assemble a
series of application products and to assemble customized enterprise applications.
According to Mike Taylor, President of Ramco Americas, "By assembly we mean
something from products or custom applications. Assembled applications provide
the fit of custom solutions and the comprehensiveness and costs of products.
It also provides continuous innovation capabilities over the life cycle of the
software. Assembled solutions are superior to and applicable to organizations
looking for both product based solutions, custom solutions and composite applications."
solution delivers a platform, called VirtualWorks, which consists of a methodology,
a set of web ready workbenches for every stage of the software development life
cycle, and a model based architecture that can assemble enterprise solutions
to a target environment of choice. With its recent announcements, Ramco is attempting
to address all four issues depicted above (see Ramco
Ships Technology And Products. Is This The Future Of Enterprise Applications?).
Although the proof is still to come based upon the experience of the early adopters,
the preliminary returns are promising since its customers are reporting that
the basic economics of application software has indeed been impacted. Of special
interest are those customers who are beginning to build composite applications
using existing applications, Ramco's business process component, and the technology
to develop applications that run through a full business process, across multiple
Model Based Architecture
Today, the subject of improving core product technology often arrives at a discussion of Model Based Architecture. In many ways, the ideas behind it are not new, since many approaches to technology share many of the same basic concepts. Although not necessarily a panacea, what makes Model Based Architecture different is that it is practical approach, which is changing some of the basic rules and paradigms of software development. It is a metadata about the application; it applies many of the basic concepts of manufacturing to the creation of code, and is rather a life-cycle tool, not just a design or development tool.
Manufacturers have been increasingly using Product Lifecycle Management (PLM) to design products from automobiles to VCRs to microwaveable dinners. PLM takes an integrated approach to the product lifecycle, from the initial idea to design & development to actual production to product retirement. In other words, PLM covers the entire lifecycle, from the idea to create a new VCR or flavor of ice cream to the design specifications, via production, managing engineering changes to product retirement. Before PLM, we had a number of individual tools that helped in part, but they were not integrated, for example, computer aided design (CAD) helped in design, whereas manufacturing execution systems (MES) only helped manage a product route in production.
Like manufacturing, we can look at today's enterprise software architecture and typically identify similar islands of automation, since there are a series of development tools that help with initial development, but little or no integration exist across the software lifecycle (i.e., specifications, design, evaluate, construct, test, deploy, and replace). Most software development tools are thus like manufacturing CAD systems helping with development but not across the lifecycle. The new enterprise applications architects should, therefore, learn from PLM and take an integrated, lifecycle view of the effort, possibly by observing Ramco's approach.
Model Based Architecture is an application development framework that allows software applications to be described in terms of "what" they must do (i.e., the business view of the software) rather than "how" they must do it (i.e., the technical view of the software). Model Based Architecture puts the emphasis on designing the business processes and the business rules up front to make sure that business functionality is complete and correct before coding begins at all.
modeling approach allows visualization of the intended solution so that business
analysts, end-users and developers can ensure that business needs are met before
implementation in software code renders changes difficult and prohibitively
expensive to make. Using the model, the framework automatically generates the
executable application instead of a programming team manually converting the
specifications into software. This code generation increases development efficiency
and typically allows generation onto a range of platform choices. Model Based
Architectures are being used for custom development and are now appearing in
packaged application products. For more information on how it addresses all
the four above realities, see What's
Wrong With Application Software? - A Possible Solution? What Is It, Why And
How Does It Fit Into Your Future.
to mention that Ramco Enterprise Series suite also addresses
the issues of being component-based and Internet-enabled. Moreover, the product
is truly platform-agnostic, and will run on any commonly accepted database and
operation system platform, and is both J2EE and .NET compliant.
Summary and Recommendations
Enterprises looking for new solutions should consider the vendors who have either rewritten their products on a new framework or are at least taking new approaches described above. Can you abandon your existing infrastructure and go to a model-based world today? Yes in theory, but that will not prove practical to the vast majority of enterprises, since the IT world is a mix of multiple applications, technologies, etc.
Thus, enterprises that are looking to fill in their existing application portfolio should look naturally first at their incumbent vendors for a solution. However, they should investigate alternative suppliers and the possibility of creating composite applications as an alternative approach. If the incumbent vendors do not adequately fill the need, vendors with strong application function plus the ability to participate in composite applications should be favored. What is required from an ideal composite solution is the ability to integrate the business process, integrate the applications and data, and supply additional functionality to "fill the gaps" to produce a cohesive, composite application that ensures transactional and contextual integrity across the entire business process including manual process/workaround, a spreadsheet, or some other solution that keeps the business process from being fully automated by applications.
Despite the user preference for a single, one-stop shop' vendor, componentized software products, interoperability standards and Internet technology will lead to fewer large-scale projects and an ongoing stream of smaller ones, all with tangible return on investment (ROI) rationale. Easy integration to third-party applications has become a key selling point for ERP vendors as thus many of them tout the provision of connectors to/from their systems and/or provision of integration development tools. However, users should vigorously question their potential enterprise applications providers the following:
Which industry interoperability standards (e.g., Open Applications Group Integration
Specifications (OAGIS), XML, etc.) are supported?
Do they provide message-based flexible interface or a rigid code-based integration?
Do they provide basic batch-run interfaces or more advanced real-time, interactive
two-way connections between applications?
The standards-based development model should ensure a tremendous amount of flexibility down the road. Enterprises that see themselves as technology leaders should consider new approaches to gain longer-term benefits from the decision. Further, although the widespread acceptance of Web services implementations will not happen any time soon, all enterprises should start learning the new protocols, standards and technologies in order to grasp the underlying business advantage of Web services, and to shift away from the software-centric mindset of largely outgoing client/server perspective.
is by all means good news for many vendors' existing customers, particularly
for the large corporations that need to integrate their internal applications
with applications from other vendors and/or who need to exchange information
with their business partners that are not necessarily usual vendor suspects'
shops. Still, while the above new technology blueprints might be impressive,
the market has often in the past witnessed how long the road is between the
vision and execution, SAP's or PeopleSoft's
huge resources notwithstanding.
Yet, the architecture will not benefit customers until products built on it begin to appear en mass. Therefore, potential and current customers with hefty integration requirements should not depart from their short-term IT investment strategies. They should also consider third-party EAI alternatives, particularly if the large corporation is looking to build integrating middleware standard corporate-wide and in the long term. Moreover, users should question their vendor's delivery fulfillment of its strategy and appreciate that migrating older instances and/or integrating them to other software will remain painstaking for some time to come.
