Introduction to the projectMotivation: To implement and integrate Product
Database Server solution to current NAPA product aiming to finding out the relation database effectivisity comparing the current shared file system.
Customer: NAPA Ltd ( computing-based systems for ship safety and performance )
Customer Goals: To implement, test and delivery a product database server, which work in the first phase together with current shared file style data manipulation. The new solution will be integrated to the application’s interface which already exists and uses its interface functions.
Project members goals: Geting the product database server work done with good quality, learning new practices and tools as a team with good team spirit.

Project current situation 85% of customer goals has been reached Reached:
1. Database ER model is ready. 2. The database has been implemented according to the ER model. 3. It is possible to test the database. 5. The architecture is ready and will support different end users. 6. Interface to the current system function “read” works. 7. Interface to the current system function “write” works. 8. Update the database Information.9. Interface to the current system function “delete” works.
Will be done during I2 iteration (not planned exactly yet):4. Replacement of the current, shared file style data manipulation by the database
server. 10. The software is possible to execute on a laptop (Win & Solaris). 11. There is a Remote procedure call (RPC) interface. (This is an extra feature!)
53% of Working effort from Total project effort have been used Requiremets current situation in Requirements Specification document

Status of the iteration I1 goals (1/2) Goal 1: To design the core architecture(ER model), the architecture in detail and
data model OK. Architecture has been changed from the first planned version and updated to technical
specification. Goal 2:The database implementation, basic classess’ impelemtation and unit
testing (read, write, delete and update) Database has been implemented and tested according to technical sepcification and ER
model. OK Read functionality has been focused, implemented and tested.OK Write functionality has been focused, implemented and tested.OK Delete functionality has been focused, implemented and tested.OK Update functionality is part of write functionality. Update works and it has been tested. OK
Goal 3:Familiarize with engineering and building environments Engineering Environment: Java, Intel compiling environment for Fortran, Visual C++
environemt for c -coding, Embedded SQL environment. Sybase –database server Building Environement: Napa Build and Eclipse (Java)
Goal 4:Familiarize with integartion and system testing environments OK, Integration and system testing environemnt is Napa environent with the new database
Goal 5: Kick-off meeting with project group, mentor and customer OK

Status of the iteration I1 goals (2/2) Goal 6: Beta release of new product data server ( functional requirements
from ”must” category) OK. Database implemented, but not integrated to UI. All functionality read, write, update and delete has been planned, implemented and tested.
Goal 7: First phase of the SEPA OK, all has been given introduction to their SEPA subjects. iteration I1 diaries is in the web site. Subjects are ( meeting practices, pair programmin and unit testing)
Goal 8, Peer testing is planned NOK, This has been agreed with mentor and customer and move to I2 iteration
Goal 9: Project monitoring and tracking OK, regulary on monday meetings
Goal 10: Reporting the project progress and work effort to customer and mentor
OK, weekly reports to customer and mentor

Updated requirements document OK
Technical specification OK, UML diagrams for all the planned features ( read, write, delete and update)
Test cases OK
Test report and test log OK
Peer testing instructions NOK, move to next iteration.
Progress report OK, this document
Release note OK
Beta version of the Product Data Server OK, it is possible to demonstrate the beta version.

Realization of the tasks Design, architecture and Requirements, over run – 12.5h
Design takes more time than planned ( Lack of current system documentation) Implementation, left 49h
Design takes more effort than planned, unit testing very demanding Testing, left 50.5h
Testing started later than planned Testing tasks has been changed as follows:
"integration testing execution" ->"static testing of code" "system testing execution" -> "dynamic testing"

Quality assessment, in I1 iteration
We made a lot of static testing during week 48 Reviews for Read, Write and Delete
Database was tested with Parser.java No problems or bugs found
Unit-tests for java-classes
Functional area Coverage Quality Comments
Parser 3 Tested
Read 2 Tested only with Unit-tests and code review
Write 1 Write tested only with Unit-tests and code reviewUpdate-function not tested with Unit-tests
Delete 2 Tested only with Unit-tests and code review
Database 2
Old and new 0 Not tested
Legend
Coverage: 0 = nothing1 = we looked at it2 = we checked all functions3 = it’s tested
Quality:= quality is good= not sure= quality is bad

Changes to the project during I1 iteration Peer test planning has been moved to I2 iteration
first draft is reday, but the document isn’t yet ready Decision for postpone to I2 iteration in project meeting, change has been
communicated to mentor and customer Testing process has been changed
Integration started very soon after implementation Unit testing has been done after integartion testing System testing has been doen only slightly

Risks Risk management weekly in project meetings
ASA developer edition java support problems discussed with Vendor Risk not realized
Developer was sick
New risks, which have also realized The documentation of current NAPA system was minimal (Overhead)
Sharing infromation in customer meetings and emails concentrating only the most important NAPA features
One developer was sick (delay in Impelemtation and testing tasks ) Build script (to exe) is broken (delay in Impelemtation and testing tasks )
try to find out, which library functions are missing with customer testing features through *.dll

Used work practices Iterative develpment
Important to start the implemetation as soon as possible Important to have milestones during the iteration
time reporting creating working hour management system takes time difficulties to add new task to the excel system Reporting practices works well
Risk management weekly during project metings
version control works well
Requirements and change management during customer meetings important to write up decisions to meeting minutes
SEPA meeting practices
works well. Important to sum up deadlines. pair programming unit testing statical metods
We are not going to make big changes to the current practices
