Every IT system is subject to a lifecycle that limits the duration of its period of use. In doing so, it passes through several stages of maturity, from development through introduction and operation to disposal.
A distinction must be drawn here between software and hardware systems, each of which follows a different lifecycle.
Software Systems
Software systems are characterised by their status as an intangible asset, which also makes their use dependent on the corresponding hardware. Software passes through the phases of development in response to a specific problem, introduction into the desired business environment (roll-out), and operation within that environment.
The development phase for software consists of concept creation, which defines the task, followed by the programming (implementation) of the source code. A subsequent testing phase paves the way for the roll-out, and a regular maintenance and update process, alongside appropriate user support, ensures smooth operation.
A disposal phase becomes relevant when the software is no longer needed or is to be replaced by a more capable application. This requires the software to be decommissioned, which usually takes place within the framework of a transformation project to ensure a smooth transition to a new software system. "Recycling" is also possible, for example by integrating the software into a broader IT system via suitable interfaces. This process is also known as Enterprise Application Integration (EAI).
Hardware Systems
Hardware systems, by contrast, have a material status, which consequently has a decisive influence on how they are treated within the framework of lifecycle management. The lifecycle encompasses largely the same phases, but different priorities apply.
The development phase consists primarily of the creation of a theoretical product concept, which is then manufactured industrially during a production phase. This may involve further sub-steps until the final product (for example, the server) is produced. The resulting IT hardware is integrated into the desired business environment (cf. roll-out) and thus becomes a business asset. The operational phase is defined in particular by the provision and maintenance of the hardware and user support.
Finally, at the end of its useful life, an approach must be found for disposal or reuse. As this involves a tangible asset, this is a considerably greater challenge than with pure software systems. This aspect is particularly relevant given the dynamics of the IT market. Due to the high pace of progress, usage cycles are shorter and "end-of-life" is reached sooner. Efficient concepts for the disposal or reuse of IT hardware therefore play a decisive role in successful IT management.
IT lifecycle management must therefore provide approaches for all lifecycle phases in order to ensure effective IT management. The process implementations of ITIL v3 represent a very sound and proven approach in this regard, placing all IT service management processes in the context of lifecycle orientation.
When developing IT systems, a concept for their eventual disposal must already be established.
What value does this create for your business?
Only those who provide a strategic concept for each phase, from development through to disposal of IT systems, can realise the full efficiency potential of IT management.
Furthermore, clear differentiation from competitors is possible, as lifecycle orientation in IT management is still not taken into account in many organisations. This means you can be among the first in your industry to unlock the associated economic benefits, particularly in the areas of image and risk management.
A closely related concept is Green IT, which provides approaches for the efficient use of IT systems. Green IT presupposes, to a certain extent, effective lifecycle management in order to achieve its associated goals.
Take advantage of far-sighted action within your IT management to secure your sustainable business success. To this end, Pröhl Consulting Berlin offers you suitable concepts for integrating IT lifecycle orientation into your business processes.
