Unit 7: Implement Phase – Discussion

able 20.1 Implementation scenarios
Implementation scenario
Big Bang
The proposed change is introduced in one major overhaul
Big Bang
Parallel
The proposed change is introduced step-by- step (e.g., by location or business unit), with the next roll-out starting before the previous one is finished
Parallel
Relay
The proposed change is introduced step-by-step with each roll-out only starting once the previous one has been completed
Relay
Combination
Advantages
• Fast to implement • Minimal overhead
Time
• A relatively faster implementation • Ability to make use
of lessons learned from preceding implementations
Time
• Opportunity for a higher quality implementation as the lessons learned from the preceding roll-out(s) can be fully taken into account and the
Time same implementation team can be used
Disadvantages
Typical use
A combination of the above mentioned implementation approaches—perhaps a small pilot and then building up to larger implementation •
Combination
• Provides the organization with the benefits of tailoring the roll-out to the specific situation Flexible yet manageable

•
Risk of disruption to the business is high Any errors may not be picked up and could have a high impact on the business
Additional resources will be required to assist with overlapping implementations Coordination of simultaneous roll-outs will be high and potentially complex
Lack of speed, as the implementation could, depending on the circumstances, take some time to complete High costs related to the duration of the project
Pitfall could be lack of communicating the rationale of this approach, as it might seem chaotic to some

Isolated BPM projects (pilot project and small to medium projects), typically with limited number of business units, regions or people involved
Large-scale projects where there is a great level of similarities across the various regions and business units
Portfolio of projects, where projects will run in parallel
Large-scale projects where specialist skills are in high demand, leveraging the same implementation team over and over again Portfolio of projects where there is a strong interdependency of the projects
Can be used in any project type Typically used in case of a transformation project, where a small project is used as a testing ground and then expanded to large and more critical parts of the organization
