Unformatted text preview: approaches built on the notion that the goalposts are
always moving. The software development community has
developed Agile methodologies based on that premise.
Agile projects use multiple, short-term iterations or release
cycles, directed by relatively simple requirements or
“user stories” that evolve with each development cycle.
When implementing EHR systems, consider adopting
Agile software development methodologies so your
implementation can stay current with best practices.
This is a case where healthcare providers can leapfrog
their counterparts in other sectors. Using modern,
SOA technologies and iterative development practices,
healthcare providers might teach their counterparts in
other sectors best practices in enterprise agility. S TRAIGHTTALK I T 35 Aim high to avoid
cloud pitfalls TIM STAMMERS S erver virtualization cuts costs and boosts IT
agility. But the flexibility that it brings to IT
operations comes at the cost of increased
complexity, which threatens to undercut its benefits.
The challenges should not be underestimated, and
the best way to meet them is to focus on the ultimate
goal: policy-based IT management, within a private
cloud. Virtualization cuts costs and boosts agility
Ovum estimates that around 70% of costs for typical IT
operations are associated with the maintenance of the
status quo and existing applications, and only 30% is spent
developing new applications that will keep businesses
profitable and competitive. Given that change is one of
the few constants in commercial life, and that IT is now
fundamental to almost all businesses, improvements to
this 70:30 ratio are invaluable.
The take-up of x64 virtualization began in development
departments, where it provided a means of consolidating 36 S TRAIGHTTALK I T The best way to avoid
problems is to begin
with an understanding
that virtualization is
a long-term project
and that the longterm goal is policybased management
of a uniform IT
infrastructure. or reducing hardware requirements. Exactly the same
virtue has propelled the technology from the development
department into production servers. Si...
