ERP Implementation, Go-Live, and Maintenance

A set of flashcards aimed at reviewing key concepts related to ERP implementation, including strategies, management, testing, risks, and maintenance.

What are the main ERP implementation strategies?

Phased, big bang, hybrid, and parallel.

What does Organizational Change Management (OCM) seek to minimize?

The risk that a new system will be rejected by end users.

What is phased implementation in ERP?

Gradual implementation of the ERP system by module or business unit over time.

What does a hybrid implementation strategy involve?

A combination of the phased and big bang approaches for different business units or modules.

What is the primary advantage of parallel implementation?

It is the least risky strategy and allows reverting back to legacy systems if issues arise.

What is the role of super users in ERP?

They are trained extensively on the ERP system and help train other users.

What is the purpose of testing in ERP implementations?

To ensure that business processes and configurations work as expected before going live.

What are the steps involved in data migration?

Data collection, extraction, cleansing, harmonization, transformation, and loading.

Why might customization of an ERP system be considered a drawback?

Customization can be expensive, may lead to issues with integration, and does not always add value to the system.

What is the purpose of a Conference Room Pilot (CRP)?

To simulate business processes in order to test system configurations and training needs.

What does the acronym ETL stand for in the context of data migration?

Extract, Transform, Load.

What is the role of a systems integrator in ERP implementation?

To fill in gaps where internal resources lack the necessary expertise.

What should a risk management plan in ERP focus on?

Identifying, analyzing, and mitigating risks associated with the ERP project.

What is the main purpose of ERP maintenance?

To keep the ERP system running smoothly by applying updates and ensuring the system functions correctly.

What are the main ERP implementation strategies?

Phased, big bang, hybrid, and parallel.

What does Organizational Change Management (OCM) seek to minimize?

The risk that a new system will be rejected by end users.

What is a major disadvantage of big bang implementation?

It requires a substantial concentration of resources and poses more risk due to forcing too much change at once.

What are the steps involved in data migration?

Data collection, extraction, cleansing, harmonization, transformation, and loading.

What does the acronym ETL stand for in the context of data migration?

Extract, Transform, Load.

What is the role of a systems integrator in ERP implementation?

To fill in gaps where internal resources lack the necessary expertise.

What should a risk management plan in ERP focus on?

Identifying, analyzing, and mitigating risks associated with the ERP project.

What is the main purpose of ERP maintenance?

To keep the ERP system running smoothly by applying updates and ensuring the system functions correctly.

What is Unit Testing in ERP?

Testing individual modules or components of the ERP system in isolation.

What is Integration Testing in ERP?

Testing the interfaces and data flow between different modules and sub-systems within the ERP.

What is System Testing in ERP?

Testing the entire, integrated ERP system against functional and non-functional requirements.

What is User Acceptance Testing (UAT) in ERP?

Validation by end-users that the ERP system meets business requirements and is ready for use.

What is Performance Testing in ERP?

Evaluating the system's speed, responsiveness, and stability under a particular workload.

What are the main ERP implementation strategies?

Phased, big bang, hybrid, and parallel.

What does Organizational Change Management (OCM) seek to minimize?

The risk that a new system will be rejected by end users.

What is the main purpose of ERP maintenance?

To keep the ERP system running smoothly by applying updates and ensuring the system functions correctly.

What is data collection in the context of ERP data migration?

The process of identifying and gathering all relevant data from various source systems that needs to be moved to the new ERP system.

What is the purpose of data cleansing during ERP data migration?

To identify and correct or remove erroneous, duplicate, or inconsistent data to improve data quality before migration.

What does data harmonization involve in ERP data migration?

The process of standardizing data from different sources into a consistent format and structure that aligns with the target ERP system's requirements.

What is data transformation in ERP data migration?

The process of converting data from its source format into the format required by the target ERP system, often involving mapping and reformatting operations.

What is data loading in the context of ERP data migration?

The final step of importing the prepared data to erp database

What are common causes of ERP implementation failures?

Poor change management, inadequate user training, data migration issues, poor project management, and scope creep.

How does a lack of organizational change management contribute to ERP failure?

It can lead to user resistance, low adoption rates, and rejection of the new system due to insufficient preparation and communication.

Why is insufficient testing a risk factor for ERP implementation failure?

It can result in critical system errors, process malfunctions, and data inaccuracies appearing after go-live, disrupting business operations.

What role does data quality play in ERP project success or failure?

Poor data quality (inaccurate, incomplete, or inconsistent data) can derail the migration process, lead to incorrect reports, and erode user trust in the new system.

How can inadequate user training lead to ERP implementation failure?

Users may not understand how to use the new system effectively, leading to errors, decreased productivity, and resistance to adoption.
