Team Foundation Server (TFS)


Agenda

� Systems

� Time Tracking Tool CCRM

� Team Foundation Server

� Task

� Problem

� Goal

� Development Process

� Architecture

� Used APIs

� Demo

� Summary


Problem

� Both systems are not linked or synchronized, meaning…

� Developers must create timesheets

� Developers must update “Completed Work”

� Developers must update “Remaining Work”

� Same data in different locations

Employee

9-11 o‘clock, hold

presentation, …

9-11 o‘clock, hold

presentation, …


Meaning…

� Doubles your work

� Uncomfortable to use

� Variations

� Progress- (TFS) and cost-controlling (CCRM) use different data


Goal

� Minimize effort

� Link progress and costs

� New CCRM version

� Plugin for TFS

=> Developers only have to use one system

EmployeeEmployee


We know what to do

but how to do it?


Development Process

� One-Man show

� Extended waterfall model

� Risk analysis

� Split up work into tasks

� Estimate time

� Track your time!


What‘s different from Fontys tasks?

� Unclear task

� Long analysis phase

� Consultation with the client

� Requirements engineering

� Click prototype

� Productive usage

� Usability issues

� Performance issues

� Acceptance tests

� Legacy systems

� Grown system with multiple versions

� “Quick & Dirty” approach


What was really done…


Components

� How do the components work together?

� Center around CCRM and TFS

� Connected with WCF/standard interfaces


Used APIs


Demo


Summary

� Be prepared for your job search!

� Synchronize time between two systems

� Simplify processes

� Don’t expect too much input

� You have to work for yourself

� Design for reusability

� Use existing APIs

� A lot of fun


Break

See you in 20 minutes…


Requirements Engineering with

Serena Prototype Composer

Speaker: Christian Hamacher


Software Engineering: A typical example


Chinese whisper: misleading communication

� We can talk about

� Functional and non-functional requirements (documents, wikis, …)

� User interface designs (screenshots, images, …)

� Data (technical instructions, entity relationship models, …)

� What is missing?

� A prototype to identify the clients needs from to


� Main advantages

� One prototype

� Minimum effort

� Understandable by

� Customer

� Project manager

� Software engineer

� Other stakeholder

Prototyping!

� This cycle repeats for different questions (e.g.

technical, graphical, …)

� Impact1:

� 80% of critical software engineering

projects miss their deadline

� 85% overdraw their budget

� 60% of project managers think that

agile methods are more successful

� Therefore, current trends are

� Agile/lean development

� Extreme Programming, Prototyping,

Scrum, …

� Iteration-based development cycles

� Improved communication between

stakeholders

Serena Prototype Composer

� Serena Prototype Composer enables IT organizations to quickly simulate process flows

and mock up UI screens to help quickly clarify requirements.

� With Serena Prototype Composer, you can:

� Define and visualize the business process workflow together with business users

� Define or refine screens to mimic the business user interaction experience using a

WYSIWYG editor

� Define system interactions over web services and map service inputs and outputs to

model elements

� Simulate behavior to understand prototype dynamics
