Agenda

Das Problem

- die eierlegende Wollmichsau gibt es nicht

- Punkt-to-punkt Werkzeugintegration hat die Komplexität N²

- Proprietäre Schnittstellen Abhängigkeit vom Hersteller und Versionen

Open Services for Lifecycle Collaboration (OSLC)

- Referenzieren ist besser als Synchronisieren

- Das WWW als Vorbild: alles ist eine Ressource und per URL addressierbar

OSLC in Aktion :: ein Projekt und reale, verfügbare Werkzeuge

- Projekt-Zeiterfassung: My internal accounting base (Miab)

- Anforderungsdefinition, Projektmanagement, Testmanagement

- UML Modellierung, Build-Automatisierung / Kontinuierliche Integration

Noch mehr Action, Zusammenfassung und weiterführende Information


Himmlisch Agil: Ein kleines bevollmächtigtes Team an einem Ort und ein simples Werkzeug, das gerade “gut genug” ist

The majority* of agile teams have less than 16 members

How about the larger projects?

Only 47% of the teams have their members co-located in one room

Ever tried to share a physical taskboard across geographies and time zones?

34% of the teams have their stakeholders in same building / floor / room

Did you ever have trouble reaching your product owner?

How many companies participate in your projects?

Does your company / your industry mandate compliance or auditing?

Bisherige Ansätze haben viele Nachteile

Universal metadata standard

“How did I ever think all those

vendors would be able to

agree?”

Single repository

“Can I really expect one vendor

to provide all the functionality I

need? And what about my

existing tools?”

Point-to-point integrations

“How can I ever upgrade one

tool without breaking

everything else?”

Standard implementations

“Did I really believe that

every vendor would rewrite

their tools on a single

framework?”

Limited choice and coverage

Slow to emerge and disruptive to adopt


Agenda

Das Problem

Datenintegration im 21. Jahrhundert Verknüpfte Artefakte im “Projekt-Web”: lifecycle resources

Inspired by Internet principles, implemented

with Internet technologies: simple interfaces for

exchange of resources

Loosely coupled: everything is a “resource”

linked together with URLs

Technology neutral: treats all implementations

equally

Minimalist: defines no more than necessary for

exchange of resources

Agile: deliver value now, add more value over

time

Openly published standards: free to implement

and irrevocable

If the entire Web can connect like this, would the same idea work for ALM?

…unlike traditional integrations that are tied to brittle, proprietary desktop and server technologies

RESTful CRUD


Jazz: Eine offene Architekur zur Integration von Werkzeugen

Embracing linked lifecycle data

(OSLC) for sharing lifecycle

resources

Defining Jazz Integration Services

for common capabilities like

administration, reporting,

dashboards, etc.

Multiple integration points / patterns

– Backend: RESTful CRUD

– Frontend: HTML preview


Jazz ist IBM’s Beitrag zur Verbesserung der Werkzeugintegration

This strategy is executed in three ways:

An open architecture for lifecycle tool integration

An open community working together to integrate and develop lifecycle tools

A catalog of products that support the Jazz initiative

Standard protocols for linking lifecycle tool data (OSLC)

Jazz Platform consisting of Jazz integration Services and

Protocols to support lifecycle integration patterns

Jazz.net – A place where stakeholders collaborate

Transparent development of Jazz architecture and

products

Lifecycle tools that use the Jazz architecture

Developed transparently in the view of the Jazz

community

Open Services for Lifecycle Collaboration Spezifikation für verlinkte (Projekt-)Lebenzyklus Daten

An open community of

individuals from industry,

commercial tools vendors,

systems integrators, open

source projects, and

academia.

Focusing on sharing of

lifecycle data (requirements,

test cases, change requests)

between tools and across the

lifecycle.

Taking a technology-neutral

approach based on Internet

standards and protocols.

Erfahrungen aus mehreren Projekten

Gutes Software Engineering ist (weiterhin) die Voraussetzung für Erfolg.

– Anforderungen müssen strukturiert werden.

– Ein formaler und doch leichtgewichtiger Freigabeprozess ist wichtig.

– Die (Nicht-)existenz von OSLC-Links hilft als Vollständigkeitsprüfung.

– Komplexe Projekte benötigen wohldefinierte Baselines.

Wenn alles im Fluss ist, ersticken Teams an den Änderungen.

OSLC Links sind sehr nützlich – aber nicht überdosieren!

– Man braucht ein (projektspezifisches) Metamodell der Artefakte

– Die Semantik der Links (Children, Implemented By, Validated By, ...)

muss den Nutzern klar sein.

Webstandards brauchen (Betriebs-)Team mit Erfahrung in Webstandards

– Stabile URLs Reverse Proxies

– (Verteiltes) Single Sign On LDAP

– Projekt On-/Offboarding und Berechtigungsmanagement PMO

Mehr OSLC in Aktion – einige ausgewählte Beispiele

Who What Description

Siemens Teamcenter &

Rational Team Concert

Coordinate product (PLM) and software (ALM) change management. Siemens is integrating change

management processes for mechanical, electrical and software systems by creating and linking Rational

Team Concert and Siemens Teamcenter change requests.

Jenkins ( Hudson)

OSLC CM Plugin

The Jenkins OSLC CM Plugin connects to different remote bug trackers via the OSLC protocol

Eclipse Mylyn, Tasktop

Dev Pro & Sync 2.0 //

Rational Team Concert.

Rational ClearQuest, …

Task-focused collaboration for Eclipse developers and ALM integration. Eclipse Mylyn and Tasktop Dev

Pro provide developers with a revolutionary task-focused interface that supports one-click multitasking,

workspace focusing, and time tracking for Rational Team Concert work items and ClearQuest change

requests. Linking support for Tasktop Certified ALM ecosystem via OSLC-based REST API.

HP Quality Center &


Improve collaboration between development and test teams. BSD Group is connecting development and

test processes by linking Rational Team Concert work items with HP Quality Center test requirements and

plans.

PLM/ALM traceability scenarios

Break down barriers between PLM and ALM. General Motors is driving integration scenarios to achieve better performance and traceability across the product and software lifecycles.

Microsoft Project &


Better collaboration between product managers and agile teams. Ascendant’s Atech Team Connector

synchronizes Microsoft project plans with Rational Team Concert release and iteration plans.

iTKO LISA & Rational

Team Concert, Rational

ClearQuest

Reduce time to defect resolution. iTKO LISA creates Rational Team Concert work items or ClearQuest

defects that include detailed, multi-tier trace information from any test executed with LISA Pathfinder.

dbMaestro Teamwork &


Manage change to your database system. dbMaestro TeamWork enables teams to manage database and

schema evolution by utilizing Rational Team Concert change management -- linking dbMaestro database

change sets with Team Concert work items.

Kernaussagen

Das perfekte Tool, dass alle akzeptieren, gibt es nicht.

Punkt-to-punkt Integration ist N² / wackelige APIs sind ein Alptraum

Verlinken ist besser als kopieren

OSLC Prinzipien:

URLs, Standardisierte Datenformate, RESTful services

OSLC basiert auf offenen Standards: XML, Dublin Core

… und ist ein offener Standard für kollaboratives Anwendungs-

Lebenszyklus-Management (C/ALM)

Es existieren bereits diverse nicht-IBM + IBM Integrationen:

HPQC, Mylin, JIRA, Mantis (PoC), Bugzilla (PoC), …

RRC, RTC, RQM, DOORS, ClearQuest, Tivoli Service Request

Manager, RSA, RSysA

OSLC ermöglicht eine schrittweise Einführung der Werkzeuge

Ein Big Bang ist nicht nötig.
