This book shows its readers how to achieve the goal of genuine IT governance. The key here is the successful development of enterprise architecture as the necessary foundation. With its capacity to span and integrate business procedures, IT applications and IT infrastructure, enterprise architecture opens these areas up to analysis and makes them rich sources of critical data. Enterprise architecture thereby rises to the status of a crucial management information system for the CIO. The focused analysis of the architecture (its current and future states) illuminates the path to concrete IT development planning and the cost-effective and beneficial deployment of IT.

Profit from the author's firsthand experience - proven approaches firmly based in enterprise reality.


Enterprise Architecture: Significance, Creation and Approach - How does Architecture Management work? - Analyses and Key Figures - IT Development Planning - Costs - Significance and Benefits for IT Governance



As the Managing Director of act! consulting GmbH, Klaus D. Niemann specializes in the development of enterprise architectures. IT efficiency and effectivity have been the focus of his more than 20 years of firsthand experience in the area of IT architecture management.


6 Planning: Creating Enterprise (S. 153-154)

Architecture Architecture takes place between two ears.

Most organizations have a map of their applications environment and infrastructure systems. How up to date and accurate is your map? Is it also used for purposes of planning, i.e. does it include representations of multiple past and future states? Are you able to run gap Analyses of current and target states? Do you have a practice of aligning your project portfolio with the measures derived from the planning of the applications environment and the gap analysis? Does this or some other procedure allow you to ensure that the various measures of technical renovation (e.g. enterprise application integration) harmonize with the IT investment strategies of the departments in your organization and that are outlined in the project portfolio?

IT Development Planning

Development planning may have a technical and/or business orientation, i.e. it may concern the infrastructure landscape and/or the applications environment. In either case, development planning represents a necessary extension of traditional portfolio management whenever its goal is not only to optimally satisfy the requirements of your clients, but also to plow ones own field, i.e. to establish the future security and stability of the current applications portfolio.

Development planning integrates the planning of new projects with the optimization of existing systems, the securing of stability and integration, the closing of gaps, the elimination of redundancies and breaches. The outstanding significance of development planning arises from the elimination of unnecessary heterogeneity and the standardization of infrastructure and application systems. The fact that heterogeneous infrastructure landscapes possess a high degree of complexity and thereby generate high costs has long since been recognized.

The heteroge
neity of applications environments always comes up for consideration when it comes to eliminating clearly redundant applications in the context of mergers and acquisitions. But have you ever taken a look at your applications environment independently of such external factors and asked yourself whether it really has to be so complicated? Lets consider an example from the insurance industry: The classic back office systems for inventory management are being developed on a mainframe in COBOL, the sales systems for mobile sales in C++, and the systems for stationary sales via sales partners in Smalltalk.

What is more, the premium calculators on the Internet have an HTML format, while the C++ computing kernels are linked via Java Servlets. The new website has been realized by an external supplier in .NET technology and responsibility for its maintenance is currently being transferred to internal employees. The new generation of inventory management is to be developed in J2EE technology, which is currently being implemented in a pilot project known as PartnerSystem.

Our scenario involves no less than six different technologies that are not a matter of programming languages, but of complete development lines, each with its own programming conventions, tools for version maintenance, testing, debugging, and perhaps even for applications analysis. Each line requires support, each requires specialists and each a human resources development program. And all of the lines will have to be technically integrated with one another. Does this come across to you as an exaggeration or a description of other peoples problems? If yes, then skip ahead to the discussion of the significance of development planning in the context of restructuring projects and standard software development.
