Some statistics #1 • Communication types used (by intensity): – Chat (MSN, Skype) – most of time – E-mails – often – Voice and video link (MSN, Skype, cell phones, TCR/Zeta) – not so often – In person (both in Zagreb and Vasteras) – also not so often 6/7/2021 11

Some statistics #2 • Some numbers – Time spent for all team mebers for meetings is about 20 -30 hours per week – Almost 500 e-mails in total 6/7/2021 12

Documentation • We documented – code – project plan, requirements, description – other documents, which will be published soon 6/7/2021 13

Used technologies • • Microsoft Windows Microsoft. NET framework 2. 0 Microsoft Visual Studio 2005 Microsoft Office PDF SVN, CVS NUnit MSN messenger, Skype, videolink, GSM, e-mail (communication), Google Search • Wiki, Collaboration panel (both rarely) • . . . 6/7/2021 14

Application requirements • Microsoft Windows XP or newer • Microsoft. NET framework 2. 0 or higher • PDF viewer for reports (like Adobe Reader) • Configured SVN server for collaboration mode 6/7/2021 15

Requirements analysis ü Data storage, Synchronization ü Objectives, Topics, Activities, Resources, Roles (Users) – the core ü Course management ü Workload management (analysis) ü Reports ü Other requirements 6/7/2021 16

Design changes • Some classes had much more in common that it seamed in the beginning • GUI redesign (few times) resulted in 8090% changed lines in the code 6/7/2021 17

Plans changes • We shifted roles during the development few times to become more efficient • We had to work during the holidays • It will take more working hours (and money) than expected (probably 10% more) 6/7/2021 18

Software development in distributed environment 6/7/2021 19

We’ve learned. . . • • • How to present our work Diferrent cultures Working in teams Microsoft. NET 2. 0 C# XML, PDF SVN, CVS Component programming MSN and Skype 6/7/2021 20

Experiences • We’ve learned a lot • We had good and bad times • Distributed development is exciting • You should try this course 6/7/2021 21

Future plans • Just few more bug fixes • Just minor changes to documentation about our progress and fullfilment of the requirements • Submit program and documentation • Get some rest 6/7/2021 22

People who made this possible • Team members – They worked hard – They’ve made a lot • Teachers/Customers – They’ve ordered the project – Nothing of this would be happened if they haven’t been here 6/7/2021 23

Any questions? (why should we change this slide? ) 6/7/2021 24
