Application performance: the missing link in the application lifecycle

Nov. 27, 2010 - PRLog -- The application lifecycle is supposed to cover software from cradle to grave. Yet in practice, most software development organizations pass off responsibility to IT operations once software is migrated to production. Likewise, IT operations is typically not involved in early stages of the application lifecycle, when software is specified, built and tested. Such siloed approaches are no longer sustainable in enterprises that demand better accountability for their IT budget spends.

Instead, IT should treat software as a durable goods product backed by express warranties that guarantee the product will last and meet its service-level agreements. IT should take a cue from smart manufacturers that have already instilled principles, such as design for manufacturing, to ensure that their products are first rate and designed for the environments in which they will be run. Ingraining such a mentality requires new levels of collaboration between software development and IT operations that starts not when software is deployed to production, but when requirements are identified. In turn, vendors must expand their limited support of point integrations between ALM and IT infrastructure and service management tools to make design for software manufacturability approaches more seamless.

Executive summary

In a nutshell
The Ovum view
Production is conspicuously absent from ALM
Throwing software “over the wall” to ITO is no longer viable
Software should be treated as a durable good
“Design for manufacturing” reduces surprises
Tips for users and vendors
To users: make the business case for bridging the AD/ITO silos
There is ROI in eliminating waste
Software warranties rebuild IT credibility, add teeth to SLAs
To vendors: products should support data and process federation
Sell beyond the silos
ITIL has promoted awareness to federate data between AD and ITO domains
No standards for integrating AD and ITO domains
Make the opportunity possible: let the customers lead
Mapping the application lifecycle to production
IT should adopt a design-for-manufacturing mindset
ALM has synergy with ITIL
Reconciling IT service delivery processes with Agile development approaches
Core assumptions
Application lifecycle stages: convergence of ITSM and APM
Inception: software requirements and ITIL service strategy
Construction: application and construction/ITIL service design
