The first step in the process is requirements gathering and analysis. The project team needs to understand the organization’s business processes, workflows, data requirements, integration needs and more. This involves conducting interviews with key stakeholders across different departments like finance, operations, sales, procurement etc. The team documents all the necessary functionality, data inputs/outputs, reports needed, security requirements and more through this process.

Second step is designing the system architecture and databases. Based on the requirements, the technical team decides on the appropriate system architecture – whether it will be a monolithic architecture or microservices based. They design the database schemas for all the main functional modules like inventory, orders, billing etc. Relationships between different tables are identified. The team also decides on other architectural aspects like external APIs, interfaces to other legacy systems etc.

Third step is designing the user interfaces and navigation. Mockups are created for all the main screens, workflows and reports. Page layouts, fields, validations, tabs, dropdowns etc are designed based on the target users and required functionality. Wireframes are created to map out the overall navigation and information architecture. Various screens are linked through defined workflows. Approval processes and alerts are incorporated.

Fourth step involves building and testing the main functional modules one by one. The development team codes the backend modules as per the defined schema and designs. They integrate it with the databases. Simultaneously, the UI is developed by linking the frontend coding to the backend modules through APIs or interfaces. Each module is tested thoroughly for functionality, validations, performance before moving to next stage.

In the fifth step, non-functional aspects are incorporated. This involves integrating additional modules like document management, workflow automations, security rules etc. Features like multi-lingual support, reporting capabilities are also developed. Performance optimization is done. The overall system is tested for stability, concurrent usage and resilience against any errors or failures during operations.

Sixth step is customizing the system as per the exact business processes of the client organization. The configuration team studies the client’s workflow in detail and maps it against the developed ERP system. Fields are tagged appropriately, validations are adjusted and approval rules are defined. System roles and access profiles are created. Required modifications if any are developed during this stage.

Seventh step is external integration of the ERP system. Interfaces are developed to sync relevant data in real-time with external applications like warehouses, delivery apps, accounting software etc. APIs are published for third parties as well. Two-way data exchange is set up according to defined standards. System is tested for integration workflows.

In the eighth step, data migration is managed. Historical data from legacy systems or manual records into defined fields in the ERP database through conversion programs. Dependent lists/dropdowns etc are populated. Default master records are created.Test migration of sample data is done before final migration.

Ninth step is user acceptance testing where the client validates that the developed system indeed meets all the requirements. User guides, help videos are prepared. Admin users perform testing first followed by power users and then all target user profiles. Bugs if any are fixed.

Final step is the implementation and go-live of the ERP system at the client organization. Warranty period support is provided. Feedback and enhancement requests are collected. Future roadmap and upgrade plan is presented to the client. Training sessions are conducted to educate employees on using the new system. Post implementation support is provided till the stability of new processes is established. Documentation is handed over along with Admin control to the client. Overall this design and development methodology ensures a seamless ERP project execution to achieve the desired business transformation goals of the organization. Detailed planning and adherence to quality standards at every step is the key to success of a large custom ERP program.

WHAT WERE SOME OF THE CHALLENGES FACED DURING THE SYSTEM ROLLOUT AND HOW WERE THEY ADDRESSED?

Any large-scale system rollout involves significant planning and preparation to ensure a smooth transition, but challenges are inevitable given the complexity of major technology deployments across a large organization. During our recent ERP system rollout, we encountered several challenges that required adaptive solutions to remedy during implementation.

The first major challenge was user training and adoption. Transitioning 10,000 employees worldwide to an entirely new system is a massive undertaking, and it was difficult to ensure all users felt sufficiently prepared to use the new system from day one in their daily workflows. To address this, we implemented a multi-pronged training approach. First, we rolled out self-paced online training modules covering the core features in the two months leading up to go-live. Next, we held in-person classroom training sessions at each major office location in the final month to allow for hands-on practice and Q&A with trainers. We designated “super users” at each office who completed advanced training to support colleagues during the first few weeks.

While training helped set users up for success, unexpected issues inevitably arose once the new ERP system went live globally. One such challenge was a higher than anticipated call volume to the central IT help desk for user login and navigation problems. To quickly resolve this, we implemented a temporary distributed help desk model. For the first two weeks post go-live, the super users spent half their time roaming their offices to be on-hand for immediate assistance, rather than returning to regular duties. This localized support was crucial in reducing wait times for help and frustration among end users.

Data migration from multiple legacy systems also posed problems. We discovered inaccurate customer records had been migrated due to faulty mapping between the old and new systems. Resolving these took additional time spent validating and correcting records which risked delaying billing, payments and fulfillment. To remedy this, managers were given transparent data quality reports and empowered our customer service teams to prioritize fixing major errors while leaving minor discrepancies to be addressed later.

Perhaps the biggest rollout challenge came from integrating the new ERP system with dozens of other business applications through custom APIs and interfaces. During testing and validation, our IT engineers uncovered stability issues, latency problems and occasional data mismatches between systems. To systematically address this, we established a ongoing integration task force with representation from each major team. They met weekly to prioritize and resolve interface issues based on business impact. They developed automated testing scripts to continuously monitor integrations for regressions moving forward.

Additional hiccups included slower than expected performance on mobile devices which impacted our field sales and service workers, as well as customized workflows not porting over correctly to the new system in some departments like manufacturing. In both cases, we assembled cross-functional process redesign teams to re-architect mobile apps and tailored workflows from the ground up to better align with the capabilities of the new platform.

While no major deployment will unfold without issues, taking a collaborative, transparent and adaptive approach helped us steadily resolve challenges as they arose. Six months since go-live, the system has now been smoothly adopted by our entire global workforce. By learning from early stumbles, we’ve established best practices and governance structures that will benefit future platform migrations and upgrades. The effort improved our technology landscape for years to come despite initial rollout speedbumps.

Thorough preparation, empowered local support teams, ongoing optimization through multidisciplinary task forces, and flexibility to redesign around platform limitations were key to addressing the diverse challenges faced during our large ERP system rollout. Continuous issue identification and prioritized resolutions kept stakeholder impact minimal as we navigated this massive technology transition.
