PROPOSED UN-AGENDA(?)

•
Everyone is at a different stage
Thoroughly described in Block material
Excellent support from the appropriate national forums
Best worked through at your own pace (IMHO)

FEEDBACK
TMA03 – LESSONS
FOR THE EMA
• Thank you all for your hard work!
• Many successful implementations, well documented
• Reports – Organisation is key!
• Use tables and diagrams for clarity
• Match headings to mark scheme
• Check terminology (see glossaries in block material)
• Revision prior to starting the EMA?
• Probably not necessary
• Re-visit only if unsure about architecture or standards and
terminology
• Manage your references
9
• Consider functionality already in word processor
“DR. JONES. AGAIN WE SEE THERE IS NOTHING
YOU CAN POSSESS WHICH I CANNOT TAKE AWAY.”

WHY BPMN
AND BPEL?
WHEN I WERE A LAD…
• We didn’t have no fancy “Process Modelling Notations”
• We had Systems Analysts what wrote “Requirements
Specifications”
• An’ then we had other Analysts what turned ‘em into
“Functional Specifications”
• An’ Lead Designers turned them into “Design Documents”
• That Programmers used to write “Program Code”
• An for every document there were a correspondin’ “Test
Specification”!
• But tell that to young ‘uns these days…
11
• And they don’t believe you!
12
MORE PROPERLY:
THE ‘V’ MODEL OF
SOFTWARE DEVELOPMENT
• Is well understood
• Easy to manage
• Specialisation of skills
BUT:
• There is an enormous “distance” between the actual
business problem and its IT solution
• Many areas for misunderstanding / mis-communication
• Very late to “close the loop” for feedback
13
• Hard to make changes / fix problems
BPMN & BPEL
Business “Owner”
BPMN
Business Analyst
Software Developer
BPEL
14
Built on a foundation of …
Lots of well defined, available web services…
TO SUMMARISE
• BPMN is a diagramming technique readily understandable
by those familiar with the “business”
• There is a fairly straight-forward process to turn this into
executable BPEL
• Some low level design choices to be made, e.g. how to
implement conditions; error handling etc.
• But:
• It relies on the existence of lots of existing, well defined,
well understood web services
15
• Without these, it becomes another traditional development
as each service must be defined and built

“WHO?”
“TOP…MEN”

Evidence of BPEL orchestration solution
•
• Stage 1 only - 8 marks
• Similar to block 4 practicals 1a, 1b, 2 & 3

EXAMPLE 4
APPROACH TO THE PLAN
• As a minimum, you need:
• Something to hand in …
• …That contains enough to sensibly reflect on!
• “Begin. Do Project. Hand in Project. End” NOT sufficient
• So you might as well make it useful…
•
•
•
•
I suggest at least 10 separate tasks
Include rough timescales (in weeks perhaps?)
Note any dependencies between tasks
But don’t go overboard! Balance doing with planning!
• Finally, start (and keep up to date) a project diary
24
• This will help with your reflection

“FORTUNE AND GLORY KID, FORTUNE AND GLORY”

APPROACHES
TO THE EMA
WHERE TO START?
1. Work through in order
• Good for the methodical
• No problem with dependencies
2. Hardest first
• Might be demoralising (or uplifting!)
• Might find dependency problem
3. Easiest first
• Might be uplifting (or demoralising!)
4. A little bit of everything at once
Work until you get stuck, move on elsewhere
Maybe good if you have missed parts of the course

SOME SUGGESTIONS…
• Read the EMA material NOW!
• Then do the workplan, submit by the 31st
• Start the XML schema and data part
• A “stand-alone” part of the EMA, worth 15 marks
• Similar to TMA02 but with more scope for structuring and
re-use. Think about your data types!
• Complete block 4
• Get a feel for BPMN / BPEL
• Then, either:
27
• Start the report section
• Try the practical (BPEL) parts of the project
“BALLOQ’S STAFF IS TOO LONG.”
“THEY’RE DIGGING IN THE WRONG PLACE!”

EMA TIPS
(FOR NEXT
TIME…)
(EMA TIPS – 1)
• Hand Something in!
• No submission = definite fail Submission = possible pass!
• There are no tricks or traps!
• You can take everything you see at “face value”
• Word count limits
• But not too challenging – 2500 “content” words
• Organise your report to help your marker!
• Follow suggested headings in EMA Booklet 1 Page 10
• Carefully read (and follow) “What to submit”
29
• EMA Booklet 1 Page 12
(EMA TIPS – 2)
• The deadline is fixed, no submission possible after cut-off
• But unlimited submissions allowed before that
• So submit early versions in case of problems later
• Only the most recent version will be marked
• Keep up to date with the T320 website
30
• Check the news section
• Take a quick look through the EMA forums
• Strongly recommend doing this about 1 week before
deadline
• Check that you haven’t missed anything
(GETTING HELP)
• Read the national forums
• Your question may have already been asked!
• Post in the national forums
• Try to provide detailed information, specific question
• But not your actual answers(!)
• E-mail me – I can answer two types of question:
• “Have I understood the question?” (Yes or no only!)
• “Can you help with this very specific problem?”
• Don’t get fixated, or give up!
31
• Move on to other parts of the EMA
