1. A Publish/Subscribe Model for Collaborative Project Management in a Decentralized Environment - Design and Prototypical Implementation
Michael Rose, 05/11/2015

2. Environment PROJECTMANAGEMENT large projects, lots of stakeholders
high complexity
diverse responsibilities
not manageable by a single person
AUTOMOTIVE INDUSTRY
long-term vehicle development projects (5 – 7 years)
highly inter-dependent structure
involvement of numerous suppliers (Tier 1, …)

3. Environment Collaboration REQUIREMENTS FOR AUTOMOTIVE PM [1]
standardized approach
early incorporation of all suppliers
synchronize project plan at early stages
clear delegation of responsibilities
open and fast communication of changes
Collaboration
DECENTRALIZATION
in-house installations
cloud-based approaches not applicable
high confidentiality and security requirements
so far no data synchronization
OEM
Supplier 1
Supplier 2

6. Research Questions 1
Which elements of the collaborative project management process need to be shared among the involved parties?
milestones
tasks
documents
dependencies … 2
How to design a distributed collaborative project management using an established model?
possible actions: publish (delegate), subscribe, revoke, …
ownership transfer
role handling
central system registry?

7. Research Questions 3
How to implement a distributed collaborative project management system suitable for highly restricted environments?
visual representation  kind (published / subscribed)  synchronization errors
notifications, actions, …
Workflows
USER EXPERIENCE
DATA EXCHANGE
no / restricted internet access
firewall regulations
high security requirements – e.g. confidentiality
INTEGRATION
PM software cPlace for prototypical implementation
data-model support, app integration, dependencies
compatibility – support for multiple protocol versions
