Start from a brief
Paste something like this.
"We're a mid sized manufacturing and distribution company (about 400 staff across 3 sites) replacing our aging on premises ERP with a cloud ERP covering finance, inventory, procurement and order to cash. We need to be live before our new fiscal year starts on 1 April. The core team is a project manager, a finance lead, an ops lead, two IT people and an external implementation partner, plus roughly 15 super users across departments. Please plan everything from discovery through hypercare, with data migration, SIT and UAT built in."
That is the before. Here is the plan Ganttastic builds from it.
Typical timeline · 9 to 15 months
The ERP implementation plan.

- 1
Discovery & project preparation
- Confirm scope, objectives and success criteria; agree the project charter and governance
- Mobilize the project team, super users and implementation partner; set up the RACI
- Provision the system landscape (sandbox, dev, QA and production tenants)
- Document current state processes and pain points; agree the target operating model
- Stand up the project plan, budget and risk/issue log
- 2
Business blueprint & fit gap design
- Run process design workshops by workstream (finance, procurement, inventory, order to cash)
- Perform fit gap analysis against standard functionality; log gaps and design decisions
- Design the chart of accounts, master data model and organizational structure
- Specify RICEFW objects (reports, interfaces, conversions, enhancements, forms, workflows)
- Sign off the functional design and integration architecture
- 3
Build & configuration
- Configure core modules to the signed off blueprint (GL, AP/AR, procurement, inventory)
- Develop integrations to banking, CRM, WMS and other third party systems
- Build custom reports, forms and workflow approvals
- Configure role based security and authorizations
- Unit test each configuration and RICEFW object
- 4
Data migration
- Profile and cleanse legacy master and transactional data
- Build and document extract, transform and load (ETL) mappings
- Run mock conversions (mock 1 and mock 2) into the QA environment
- Reconcile migrated balances and record counts with finance sign off
- Freeze data cleansing scope ahead of cutover
- 5
Testing (SIT & UAT)
- Run system integration testing (SIT) across end to end process flows
- Run user acceptance testing (UAT) with super users against real business scenarios
- Test integrations and performance under production like data volumes
- Log, triage and retest defects against agreed exit criteria
- Obtain UAT sign off and readiness input for the go or no go decision
- 6
Training, cutover & go live
- Deliver role based end user training and quick reference guides
- Run a mock cutover / dress rehearsal and finalize the cutover runbook
- Hold the go or no go decision and execute production cutover (final load and reconciliation)
- Go live and provide hypercare / stabilization support
- Run the post go live review and hand over to business as usual support
Key dependencies
- The business blueprint must be signed off before build starts, because configuring against an unapproved design almost guarantees rework.
- Data migration depends on both a stable configuration to load into and cleansed legacy data, so data profiling should begin early even though the final load waits for cutover.
- SIT cannot start until integrations and RICEFW objects are unit tested, and UAT cannot start until SIT defects are cleared and a representative data set is loaded.
- Go live is gated by UAT sign off, a successful mock cutover and a ready cutover runbook; skip any of these and the go or no go decision is really a guess.
Timeline risks
- ERP projects slip most on data migration and scope: dirty legacy data and unresolved fit gaps quietly expand the build, and balance reconciliation always takes longer than planned.
- Protect the timeline by running at least two mock conversions, freezing scope after blueprint sign off with formal change control, and releasing super users from their day jobs during UAT.
- Buffer two to four weeks before go live for defect resolution and a full dress rehearsal, and avoid floating the go live onto a period end or fiscal boundary without contingency.
