Reducing TCO through Effective IT Life Cycle Management

News Millenium Micro - Reducing TCO through Effective IT Life Cycle  Management

Life Cycle Management is a critical component of an optimized IT service.  By keeping it in mind within the context of your purchase and support decisions, you can count on getting better value for each dollar of your IT spend, over a longer period of time going forward.  


The Goals behind Life Cycle Management

The objectives of actively managing the Life Cycle of your IT systems generally include:

1. Maximizing Usable Asset Life; depreciate and amortize assets over a longer period, reducing procurement overhead as a percentage of Total Cost of Ownership (TCO)

2. Maximizing Availability, Reliability, and Security; operate assets in the most stable and supported Life Cycle Stages (whether that support is internal, from a service provider, or the manufacturer)

3. Granular Tracking of your IT fleet Inventory and Costs; necessary for budgeting

4. Minimizing Operating Expenses (identify and mitigate high-cost assets)

5. Ensuring Loss Prevention & Environmental Stewardship  

Life Cycle Management is complicated by the fact that some of these goals are conflicting, and must be balanced within the context of your existing infrastructure, budget, and priorities.  Maximizing usable product life requires deployment relatively early in the product life, while maximizing availability, reliability, and security requires diligent research, recipe development, compatibility testing, and planning for training, deployment, maintenance and support.

Technology Life Cycle Stages

The life of an IT asset can be modeled into various stages for purposes of making educated decisions on when to adopt, or replace.  For explanatory purposes, we’ll discuss these stages in the context of Operating Systems, although the general properties are similar for hardware or other software.  While the timing of these stages isn’t always obvious, they can generally be worked out from the product usable life (ie. Data sheet Mean Time Between Failures for hardware, and/or engineering and support plans of the manufacturer for software.)

1. Bleeding Edge: Product is new to market, and heavily advertised, but with little or no established user base.  General availability of knowledge and expertise on this product is limited, and product may contain significant bugs and vulnerabilities.  Little compatibility testing with 3rd-party hardware or software has been done.  Adoption of products in this stage is very risky, and will require relatively high levels of downtime for maintenance & patching.  How long this stage lasts depends largely on the early market adoption rate, how well-received the results are, the level of attention it receives from Security researchers and media, as well as the responsiveness of the manufacturer to bug reports and feature requests.  This stage typically lasts at least 6 months after commercial release, and the transition into the next stage is somewhat subjective (ie. drop in the rate of patch releases.) Example: Windows 10 

2. Cutting Edge: If the product is well-received and business-appropriate, adoption by medium-sized businesses picks up momentum.  Some enterprise customers may start pilot testing of the product in this stage, although wholesale adoption of the product in that business segment is unlikely except for SMB’s.  Current Example: Server 2012 R2.

3. Modern: If reviews, pilots, and deployments to date are well-received, and no major vulnerabilities or bugs are outstanding, this stage is usually triggered by the release of the first service pack.  Most larger enterprise customers deploy to production in this stage.  Generally products reach this stage are considered successful because all major bugs and incompatibilities have well-known, well-documented solutions.  This stage generally ends with the termination of mainstream support by the vendor (but the product is still supported & patched for new bugs and vulnerabilities), unless the replacement product from the manufacturer has not yet been well-received by enterprise customers for planned adoption.  Current Example: Windows 7

4. Old: Generally this stage starts with Extended Support period by the manufacturer.  Major deployments by customers starts to taper off, in favour of the next replacement product (and the potential for a longer usable life for the new install) rather than one that will be obsolete soon.  Most customers will already be actively piloting replacement products by this stage, and deploying fully into production before support for the current product is dropped by the manufacturer.  Note that for hardware, this stage may be extended past parts availability from the manufacturer if the customer has acquired sufficient spares (or can do so from 3rd parties.)  Current Example: Server 2008

5. Obsolete: The product is no longer supported by the manufacturer, except under paid special arrangements, nor is it patched for newly-discovered bugs or vulnerabilities.  Few organizations run assets in this stage due to inherent risk, unless they run into technical or financial hurdles migrating to a replacement product.  Current Example: Server 2003

Asset Usable Life

For software, usable life is determined predominantly by the engineering and support plan of the manufacturer.  Operating systems typically are supported for 5 to 10 years, and applications can very widely, from as few as 2 years to as much as 5.

Beware the Hype

As a key decision-maker in your organization, it’s important to be consciously aware of manufacturer / vendor pressure to adopt the latest version of their hardware or software.  Manufacturers have structured their pricing over the lifetime of a product to exert a lot of influence over retailers to encourage early adoption, which results in quicker payback of their R&D spend and improved bottom line.  This doesn’t necessarily deliver the same favorable results to customers adopting product too prematurely.

Many SMB’s cannot afford to have a sufficient number of qualified internal IT resources to efficiently manage Life Cycle management thoroughly in-house.  Using a Trusted Service Provider in an established partnership, who knows your business, to develop your recipes and deployment plans allows you to be sure these are tailored to your specific technological and business conditions, at a reasonable cost.
