Theater Enterprise-Wide Logistics System (TEWLS)
What is TEWLS and why do we need it?
TEWLS stands for Theater Enterprise-Wide Logistics System and will
replace the presently used TAMMIS in USAMMCE on 19 Nov 2009. TEWLS
is based on SAP software, and integrates multiple business
processes, i.e. Inventory Management, Warehouse Management, Kitting,
Financial Management, etc., across the Enterprise or organized
business activities into a single Master Database.
What is the background
Several years ago, the AMEDD decided to build and implement a new
system instead of spending millions of dollars to upgrade the TAMMIS
system. The software selected to replace TAMMIS was SAP. TEWLS is
the Armys initiative to migrate the capability for theater level
Class VIII Supply Chain Management (SCM) from the Theater Army
Medical Management Information System (TAMMIS)-Medical Supply (MEDSUP)
into a SAP-based, enterprise architecture. TEWLS will have a joint
medical information architecture that enables enterprise-wide
medical interoperability within the U.S. Military Healthcare System
in support of both peace time and operational environments.
Why replace TAMMIS?
TAMMIS was developed in 1985 and has become complex, obsolete, and
lost its effectiveness to adequately support our business processes.
It also does not meet Department of Defense (DoD) security standards
for software running on a DoD network.
