Chapter 6 Flashcards
ERP implementation strategies
- determines how the project gets organized, as well as the resources and time required for its implementation.
-The main strategies are phased, big bang, hybrid, and parallel. - criteria for choosing an implementation strategy: company size and complexity , urgency to implement, risk tolerance level, resources applied to the project, project scope.
Phased implementation
-incremental/waived: the project team gradually implement the ERP system by module, business unit, or geographical area overtime. Slowest implementation approach but minimize risk. Easier to manage and put less strain on project manager and project team. Can lead to change fatigue and burn out.
Big bang implementation
- also known as direct cut over: entails rolling out all modules at the same time, resulting in one go live or cut over date.
- disadvantages: implementation is more intense and requires a substantially higher concentration of resources, more risk.
- advantages: generally can go live with less time and cost, reduces the need for temporary interfaces, less change fatigue
Hybrid implementation
-combination of phased and big bang approaches. Companies may choose to use the Big Bang approach for smaller business units and phase approach for larger business unit.
Parallel implementation
- both the legacy systems and the new ERP system are run simultaneously for a period of time post to go live
-Advantages: least risky of all strategies, can revert back to the legacy in case there are problems.
-Disadvantages: most labor-intensive, costly, confusing, and constant change management progress.
Organizational change management
- The structured approach for minimizing the risk that a new system will be rejected by end users. The more time devoted to OCM, the smoother the implementation will be.
-Hesitancy or resistance must be anticipated and managed through change management techniques that include: education, training, communication.
Three facets of OCM
-education: understanding the why behind ERP should help foster feelings of ownership and enthusiasm rather than fear and uncertainty.
- Communication with employees should be creative, consistent, and frequent. Reiterate what changes are coming and how that will affect employees jobs
-Training is often the most overlooked and under budgeted ERP cost component. Could incorporate train the trainer methodology
Vanilla implementation
Very few customizations are required, configuration is mostly what is done.
RICEF
- reports: custom reports that need to be designed
- Interfaces: connecting two or more systems so DATA can pass back-and-forth
- conversions: data must be converted from the format in the old system to the format required by the new ERP system
-enhancements: adding to the standard ERP code by making use of customer exits, which are pre-defined brakes in the software code where custom code can be inserted. - Forms: custom output documents
Bolt on technology
- A Bolt on is in a artificially intelligent execution system that provides very specific functionality or technology to complement an ERP system.
- gaps can be closed by bolt ons and customizations - example: RF ID, barcoding, electronic data interchange
Conference room pilot
- used by the project team to simulate business processes to ensure that they work properly
-key benefits include: define processes for configuration, identify the fits and gaps to determine customization needs, pinpoint impact to estimate employee training and OCM needs, test the system prior to go live
Types of testing
- unit testing involves checking the discrete steps in a process or meeting the business requirements. Example: testing entering a sales order
- Integration testing ensures that into end business processes run smoothly. Example: testing the entire purchase to pay process
-User acceptance testing is the final round of functional testing whereby process owners sign off that their area is ready to go live. Example: process owner signs off that the purchase to pay process works as expected
Types of testing part two
-performance testing determines how well the ERP system and database handle a given workload in terms of stability, speed, and responsiveness
-Data mapping testing ensures that data is passing back and forth between systems interfacing with ERP
- authorization testing ensures that and users have the proper permissions into the ERP system commensurate with their rules.
-back up and recovery testing ensures that a company can both make copies of its data and store it offsite and retrieve the data from back up.
Super users
- have been trained extensively on the ERP system and the new business processes. Prepared to train others leading up to go live in afterwards.
Systems integrator 
-most ERP implementations will require a system integrator for example Deloitte, to fill in gaps where internal resources do not have the expertise
