Introduction to the project

Customer: Houston Inc. Project: Loan Shark

Design and develop a Java EE online demo credit application system for unsecured customer loans

No human interaction from the banks side -> everything automated

Main deliverable: Demo for marketing purposes

Built using Java EE technologies Java Enterprise Edition 5 with EJB3 and JPA using JBoss Application Server 4.0 and JBoss

Hibernate Java Server Faces and Facelets using JBoss Seam 1.2

Back end

Independent of the user interface About 15 methods in the interface between back end and front end Central element is the management of the business process

Business process is started when the user fills an application When the user comes back later the same process instance should be continued Changing the process should not require changes to the core code

Process has evolved during the course

Javascript prototype

The customer wanted something to show up as fast as possible We developed a html prototype with Javascript tying the pages together Required a lot of effort As a result we did not have anything built upon the back end at the end of I1

Thus nothing that could be tested with test case based testing or exploratory testing Branded versions a further digression

The real thing

Entire team working on the same thing Many new technologies for everyone

Combining the back end with the JS prototype Still a lot of new issues, mainly with input validation and navigation

The real thing, without major bugs

Time to tie up loose ends Find and fix bugs Finalizing

Motivation boosters

Software size Non Commenting Source

Statements (NCSS) Roughly equivalent to LOC Other files calculated with wc -l

XML files hard to calculate as most stuff came with the stub

Branded JS prototypes missing Hard to calulate as much of the

code is identical to the original protype

I2 has mainly been about the GUI

Business Logic and the Process management sligthly trimmed

Results of the project

Loan application for marketing purposes built using the JBoss application stack

Code base is transferred to Houston for further development Documentation consists of on-screen help, architecture document and code

comments

HTML+CSS+JS prototypes for demo purposes 1 official 2 personalized versions

A load of documents and materials used during the project Project plan, risk management document, QA plan, requirements document,

architecture document etc. Test logs, test cases, test charters, usability test reports etc. 3 paper prototypes, of which one was chosen to be developed

Used work practices

Used practices Development in the same place at the same time [excellent] Pair programming [excellent] Technology training [good] Weekly scrums [good] Weekly reporting with progress and risks [good] Retrospectives for process improvement [good] Riskit-method risk management [good] Motivation boosters [not good, not bad, mostly funny] TDD [tried, cancelled]

Changes TDD was not enforced, but unit tests were required before commit Tasks have been presented in more usable ways for each iteration and

developers have had a chance to change unsuitable granularity

Risks

No NEW major risks have materialized during I2 Used Jyrki Kontio’s Riskit method to develop our risk management.

Including identification, analysis, control, monitoring and more (see http://users.tkk.fi/~wawilson/houston/Deliverables/documents/bin/view/Main/RiskManagementPlan.html for details)

Risks are separated in the risk management document

Changes to the project

Project was divided into simultaneous subprojects There was a need to get a prototype out fast

Additional html prototypes needed

TDD was skipped as too demanding for our use
