SOFTWARE ENGINEERING PROCESS

Business has a problem The customer does not always know what he wants


SOFTWARE ENGINEERING PROCESS

62 percent of IT projects fail 49 percent suffered budget overruns 47 percent had higher-than-expected maintenance costs, and 41 percent failed to deliver the expected business value and ROI

25 percent of all IT projects get cancelled IT departments don't take into account the time required

between design and development and QA is not adequately understood and budgeted into projects'

timelines.

JAVA LANDSCAPE


OPEN SOURCE VS BINARY


BUYING SOFTWARE


no access to the source code want to add a feature? can't. want to fix a bug? can't. want to do a security audit? can't. want to give copies to your

friends? can't, legally.

for fixes/improvements, wait for the “upgrade” new bugs, more money, runs

slower (needs new computer)


THE ALTERNATIVE?


BENEFITS OF OPEN SOURCE

Reliability Stability Auditability Cost Flexibility and Freedom Support and Accountability


THE JAVA LANDSCAPE

19825 Java projects!!!

APRIL 9, 2023 | SLIDE 49(*) Input: “Hype Cycle for Business Process Management, 2008”


WHAT’S THE FUSS ALL ABOUT?

“Business process” An (organized) way of “doing things” … with certain goal (eg making money)

Not an IT concept 1723-1790, Adam Smith: The pin factory 1863-1947, Henry Ford: mass production

– Assembly lines


NOT AN IT CONCEPT

1900-1993, William Edwards Deming Japanese production boom (after WWII) Quality control techniques Improved production through insight in processes

(Deming) quality circle

BUSINESS PROCESSES ARE EVERYWHERE

Tax system Library: acquiring and returning a book Ordering a ticket for a concert Getting up in the morning



Tax system Library: acquiring and returning a book Ordering a ticket for a concert Getting up in the morning … Any company - any product - any service

They all have business processes

Which means Business processes = doing business


THE POWER OF PICTURES

Communication medium the diagram Simple and easy to understand


BPM SELLING POINTS

Bridge between IT & the business No disconnection between

What business expects What IT delivers

And forcing the business people to align

Business changes are rapidely implemented Agile

Visibility Monitoring, CEP, KPI, data-mining, … Making decisions in real-time
