Chapter 8 – Enterprise Systems (my least favorite chapter)

– Early systems were in accounting, payroll, A/P, A/R
BUT in Silos as they were standalone
– 1980s through today – “Enterprise” systems

UMass
– Blackboard/Canvas – Online Learning (linked for registration, but not grades)
– Wiser – Registration, Grades, Bills..
– Email – (Actually not at UMass)
– Blogs
– Simnet, Connect (Actually not at UMass)
– Website
– Payroll, A/P, A/R, Cafeteria, IT Requests

– Sort of integrated (same ID/PW) but not fully (no Single Sign On) like Amazon/Google
– “Legacy” systems – Are “old” – things have been around and might be/might not be integrated

– Big organizations (SAP) started to develop Enterprise Resource Planning system (ERP). Example of a large Enterprise System.

Three categories of Enterprise Systems
-Supply Chain Management (SCM)
-Customer Relationship Management (CRM)
-Enterprise Resource Planning system (ERP)

SCM (Supply Chain Systems)
Recall what supply chain is Fig 8.5
Raw Materials (Supplier) -> Manufacturer -> Distributor -> Retailer -> You
– Links systems across the whole chain.
– COMPLEX! Each entity has its own systems, and sometimes they enforce rules on the upstream & downstream entities.
– In Supply Chain, Money flows upstream & materials/goods flow downstream
– Some companies do it well – Dell with its JIT systems, Amazon, Walmart (RFID)
– Think what happened to it during the pandemic – fell apart…

Customer Relationship Management
– Focus on the customer, rather than the product.

ERP – As in SAP – Big systems that enterprise wide focus on the product, rather than customer/

Another example of doing Enterprise systems – Electronic Health Records

These days, ERP and CRM are merging and going to the cloud.
– Integration is NOT EASY.

Amazon, while doing SCM & ERP well, has had lots of issues
– Somali Immigrants – Working conditions are inhumane at many distribution centers
– Search for its own products – Antitrust issues with this
– Taking over our cities – Is it a monopoly?
– Literally shipping trash & counterfeit goods
