Traditional IT Definition for Middleware
MIDDLEWARE (mid´&l-wār) (n.)
Software that connects two otherwise separate applications. For example, there are a number of middleware products that link a database system to a Web server. The term middleware is used to describe separate products that serve as the glue between two applications. It is, therefore, distinct from import and export features that may be built into one of the applications. Middleware is sometimes called plumbing because it connects two sides of an application and passes data between them.

Suggested definition for the Lab IT Domain
MIDDLEWARE (mid´&l-wār) (n.)
It is an information system dedicated to the management of the Lab Test production. It is based on a reliable and flexible communication engine.
“Middleware can be considered the information processing hub of the new Lab.” D. & M. Winsten

Suggested definition of an Open System
OPEN SYSTEM
It is a system that allows connectivity and associated interoperability to any manufacturer’s devices. It is a generic solution independent of instrument, automation, LIS vendors. It also supports all Lab disciplines (Biochem., Hem., Immuno., Micro., …).
“Open” is an approach not a classification.

Concepts On Information Management
Access to information is the key factor : “Push” system (i.e. Alerts)
Important Information Updated in real timeOn one screen, and complete (no post-it technology!)Detailed information available in maximum 2 mouse clicks
Automate management of the information Automate the access: Click on Rerun Box to display a Rerun List
Navigation“Switching without losing context”
Control Panels, Dashboards
“The Lab. is an Information business”

Concepts On Information Management
Real-Time & Automated processesResponse-Time and User-FriendlinessContinuous flow and not batch driven
Not only Push the information but do it in Real-Time
A Real-Time process produces information.
A Batch process may produce data only !Either before of after an event => too late or too earlyRequest (Pull) data rather than being Informed (Push)
Real-Time processes manage and supportThe whole Lab workflow and associated tasksThe verification of test information data (delta check, plausibility check, normal ranges)The broadcasting of reports

Change the Legacy LIS, or enhance it with a MiddlewareSolution?
How to best cope with evolution changes?
Perform a detailed analysis of the existing situation with focuson Processes & Workflow:
Collect the data• Key Metrics / Factors
Confirm the workflow• Routine / Exceptions• Bottlenecks
Real-Time or Batch?
What are the issues to be addressed,
What are the problems to be solved?
To do list: suggestions

How to best organize the test production?
Consolidation of workstations / work cells
What to automate in the decision Making?
Optimization of resources utilization and outcomes
• Test menu-reagents, • tubes requirements, primary vs.. secondary samples• Routine and other shifts
Backup / “degraded” mode
Find the right balance between complexity / flexibility / maintainability
Command & Control the system

Why use a Open Middleware solution?
Improve productivity while ensuring / maintaining the necessary quality standards
Get more work done with less resources (staffing)
Minimize to an absolute minimum extra work (repeats)
Being Alerted immediately to correct a problem before time, reagents, resources, have been wasted
Increase Lab competitiveness
Decrease Turnaround time
Decrease Production cost
Access to newer technology, added-value functionality
Offers down-time redundancy to the legacy LIS
