What is Enterprise Resource Planning?
Enterprise resource planning is a company-wide computer software system used to manage and coordinate all the resources, information, and functions of a business from shared data stored. It is an electronic resource planning of an enterprise. It is highly safe as data is protected in a particular server. Only individuals authorized to edit and save any data within the Enterprise resource planning system can do it. The current business environment is largely characterized by extensive use of information technology systems that were not there initially. Many companies now face the challenge of changing customer needs and rising competition. This compels modern organizations to reduce costs are they try to efficiently coordinate production, supply, and demand in the global business environment (ERM Initiative Faculty, 2014). As the market become increasingly competitive, there is great need for companies to improve their business practices. In addition, organizations need to share critical information with their customers, distributors, and suppliers. Moreover, all departments within an organization must upgrade their systems in order to communicate accurate information on a timely manner. In order to achieve all these objectives, companies are implementing enterprise resource planning systems (Umble, Haft and Umble, 2003).
Enterprise Resource Planning software aids and controls the ERP management system, which is a system that integrates and automates all facets of business operations. This includes planning, manufacturing, and sales, while more recent ERP software products encompass marketing, inventory control, order tracking, customer service, finance and human resources as well.
What are the major purposes of an Enterprise Resource Planning System?
Therefore, enterprise resource planning has two major purposes. First, a company implements an enterprise resource planning system in order to have a unified enterprise view of the business that integrates all departmental function. Second, companies that implement enterprise resource planning systems are interested in having an enterprise database where it can enter, record, process monitor, and report all business transactions (ERM Initiative Faculty, 2014). According to Umble, Haft and Umble (2003), a unified view of an enterprise requires a high level of coordination and cooperation among all departments in a company, which can best be achieved through effective enterprise resource planning.
Companies that are planning to implement enterprise resource planning systems should consider a number of critical success factors. Umble, Haft and Umble (2003) point out that implementation of an enterprise resource planning is a very expensive process that is characterized by numerous risks. It is therefore important to examine factors that will ensure successful implementation. One of the critical success factors for enterprise resource planning implementation is clear understanding of strategic goals. The key people in the organization must define the specific needs that the enterprise resource planning will address as well as specific goals that the company needs to achieve. In addition, for implementation of enterprise resource planning to be successful, the top management in the company must demonstrate commitment. An executive management committee needs to be formed to support and champion the projects (Umble, Haft and Umble, 2003).
Successful implementation of enterprise resource planning also requires a company to focus on effective project management. Effective project management includes clear definition of project’s objectives, creation of a work plan, and establishment of methods to assess the progress of the project. Furthermore, proper organizational change management is very critical for successful enterprise resource planning implementation. This is because already existing organizational structure may not be compatible with the new system that is yet to be implemented (Umble, Haft and Umble, 2003).
Again, successful implementation of an enterprise resource planning requires a great implementation team that consists of experienced and flexible individuals who are ready to steer the organization forward. The implementation team will play the role of creating the original project plan and of ensuring that all resources required for the implementation are available. In addition, for an enterprise resource planning system to work properly, there must be high level of data accuracy. Data accuracy is a critical success factor in an enterprise resource planning implementation because any wrong data is likely to affect all departmental functions in an organization. Other factors that must be considered by companies that are willing to implement an enterprise resource planning system include focused performance measures, extensive education and training of implementation teams, and high degree of consistency in the way all implementation activities are carried out (Umble, Haft and Umble, 2003).
Risks In Implementing An Enterprise Resource Planning System
Implementation of an enterprise resource planning is a vast process that poses numerous risks to companies. Such risks affect the outcome of business processes, and this calls for the great need of mitigating them. The first risk in enterprise resource planning implementation is associated with inappropriate project scheduling (O’Leary, 2004). Many companies underestimate the resources and time required for successful completion of enterprise resource planning implementation. For this reason, they experience problems in projects planning which makes the implementation process to experience a setback. In addition, organizations find it difficult to meet timelines thereby interfering with departmental functions. According to ERM Initiative Faculty (2014), the best method to mitigate risks associated with project scheduling is to establish targets that can be accomplished on time by every individual member of the implementation team.
The second risk in enterprise resource planning is associated with data management, specifically data conversion and validation. Risks associated with data conversion and validation occur as a result of poor timing and improper resource allocation. In order to avoid data management risks, companies should conduct comprehensive data risk assessment and test programs used in mapping of data structures (O’Leary, 2004). Technical risks form the third type of risks that pose a big challenge to companies implementing enterprise resource planning. Customization is a very important aspect that must be considered when implementing an enterprise resource planning system. However, many organizations implement enterprise resource planning with very little customization. Managers often pay little attention to customization to an extent that they end up increasing the costs of implementation. The best way to mitigate risks associated with technical issues is to align customization with the life cycle of system development (O’Leary, 2004).
The fourth risk faced by companies implementing enterprise resource planning is associated with lack of involvement from the functional areas that are charged with the responsibility of ensuring successful implementation. For instance, implementation teams may fail to play their roles in ensuring that all project activities are effectively performed. This may affect decision making and even prevent completion of the implementation process. In order to mitigate risks associated with functional area involvement, managers must use effective employee motivation strategies in order to retain talented teams who can perform their functions effectively (ERM Initiative Faculty, 2014).
Suppose a company succeeds in implementing an enterprise resource planning, it must ensure that its software is always stable to allow constant flow of operations. In addition, the company needs to be very careful when adding any new software and hardware in future. Again, an organization that has successfully implemented an enterprise resource planning must be patient to see the system bring about positive impacts to departmental functions (Umble, Haft and Umble, 2003).
Essential Factors for Successful Enterprise Resource Planning Implementation
Implementing an ERP system is a complex process that requires careful planning, execution, and monitoring. To ensure the successful implementation of an ERP system, several critical factors must be considered.
Clear Understanding of Business Requirements
Before implementing an ERP system, it is essential to have a clear understanding of the organization’s business processes, goals, and requirements. This involves conducting a thorough analysis of existing processes and identifying areas where the ERP system can bring improvements. A well-defined scope and objectives will guide the implementation process and ensure that the system aligns with the organization’s needs.
Strong Project Management
ERP implementation is a large-scale project that requires strong project management to keep it on track. This includes setting realistic timelines, allocating resources effectively, and managing risks. A dedicated project team with members from various departments should be established to oversee the implementation, ensuring that all stakeholders are involved and that the project stays within budget and on schedule.
Executive Support and Buy-in
For an ERP implementation to be successful, it is crucial to have the support and buy-in from top management. Executive support ensures that the project has the necessary resources and that any obstacles can be addressed promptly. Moreover, when leadership is committed to the project, it encourages the rest of the organization to embrace the change and work towards its success.
Change Management and Training
Implementing an ERP system often requires significant changes in how employees perform their tasks. Effective change management is necessary to help employees adapt to the new system and processes. This includes providing comprehensive training to ensure that users are comfortable with the system and can use it effectively. Addressing concerns and resistance to change early in the process can significantly improve the chances of a successful implementation.
Data Migration and Quality
Data migration is a critical aspect of ERP implementation, as it involves transferring existing data from legacy systems to the new ERP system. Ensuring the accuracy, completeness, and consistency of data during migration is essential to avoid issues that could disrupt operations. Data cleansing and validation should be performed before migration to ensure that the new system operates with high-quality data.
Continuous Monitoring and Improvement
Even after the ERP system is implemented, continuous monitoring and improvement are necessary to ensure that it delivers the expected benefits. Regular reviews, performance assessments, and feedback from users can help identify areas for improvement and optimize the system’s performance over time.
Different Types of Enterprise Resource Planning Architectures, Their Benefits and Limitations
Enterprise Resource Planning (ERP) systems can be designed using various architectures, each catering to different organizational needs, technological environments, and operational scales. The architecture of an ERP system determines how its components are structured and how they interact, affecting everything from implementation to performance and scalability. This discussion will explore the different types of ERP architectures and their respective benefits and limitations.
Monolithic Architecture
Overview
Monolithic architecture is one of the earliest and most traditional forms of ERP architecture. In this model, the ERP system is designed as a single, unified application where all modules (such as finance, HR, supply chain) are tightly integrated and run on a single platform.
Benefits
- High Integration: Since all modules are part of a single system, data consistency and integration are generally strong, minimizing data silos.
- Simplified Management: With one system to manage, the complexity of maintaining and upgrading the ERP system is reduced.
- Ease of Use: Users typically experience a consistent interface and workflow across all modules, which can simplify training and daily operations.
Limitations
- Limited Flexibility: The tightly coupled nature of monolithic architecture makes it challenging to modify or scale specific parts of the system without affecting the entire application.
- Vendor Lock-In: Organizations may become dependent on a single vendor for updates, customizations, and support, limiting their ability to adapt to new technologies or business needs.
- Scalability Issues: As the business grows, the monolithic architecture might struggle to scale efficiently, leading to performance bottlenecks.
Service-Oriented Architecture (SOA)
Overview
Service-Oriented Architecture (SOA) is a more modular approach to ERP design, where the system is composed of loosely coupled services or components that can be independently developed, deployed, and maintained. Each service represents a business function, such as order processing or inventory management, and communicates with other services via standardized protocols.
Benefits
- Flexibility and Modularity: SOA allows organizations to easily add, remove, or modify individual services without disrupting the entire system. This modularity facilitates customization and adaptation to changing business needs.
- Interoperability: SOA can integrate with other systems and applications more easily, enabling organizations to leverage existing investments in technology.
- Scalability: By distributing services across different servers or environments, SOA can handle increased loads more effectively, improving system performance.
Limitations
- Complex Implementation: The modular nature of SOA can lead to increased complexity in system design, requiring careful planning and expertise during implementation.
- Higher Initial Costs: The need for specialized tools, technologies, and expertise can result in higher initial costs compared to traditional monolithic architectures.
- Potential for Latency: The use of multiple services communicating over a network can introduce latency, which may affect system performance, especially in real-time applications.
Cloud-Based Architecture
Overview
Cloud-based ERP architecture involves hosting the ERP system on cloud infrastructure, provided by third-party vendors. This architecture can be deployed as Software as a Service (SaaS), where the entire ERP system is delivered over the internet, or as a hybrid model, combining on-premises and cloud-based elements.
Benefits
- Cost-Effectiveness: Cloud-based ERP systems typically have lower upfront costs, as they eliminate the need for expensive on-premises hardware and infrastructure. Organizations pay for what they use, often through a subscription model.
- Scalability and Flexibility: Cloud-based systems can scale up or down easily based on the organization’s needs. They also offer greater flexibility in accessing the system from anywhere, which is beneficial for remote or distributed teams.
- Automatic Updates and Maintenance: Cloud providers often handle system updates, security patches, and maintenance, reducing the burden on internal IT teams.
Limitations
- Data Security and Privacy Concerns: Storing sensitive business data in the cloud can raise concerns about security and data privacy, especially if the data is subject to regulatory compliance requirements.
- Dependency on Internet Connectivity: Cloud-based ERP systems require a reliable internet connection. Any downtime or connectivity issues can disrupt access to critical business functions.
- Limited Customization: While cloud-based systems offer some degree of customization, they may not provide the same level of flexibility as on-premises solutions, especially in highly specialized industries.
Two-Tier Architecture
Overview
Two-tier ERP architecture involves deploying a primary, centralized ERP system at the corporate level, while individual business units, subsidiaries, or regional offices use their own ERP systems. These systems are integrated to ensure data consistency across the organization.
Benefits
- Tailored Solutions: Two-tier architecture allows subsidiaries or business units to use ERP systems that are specifically tailored to their needs, while still maintaining integration with the corporate system.
- Cost Efficiency: By deploying smaller, specialized ERP systems at the subsidiary level, organizations can reduce the costs associated with a single, large-scale ERP deployment.
- Flexibility in Growth: This architecture supports mergers, acquisitions, and expansions by allowing new entities to integrate their existing ERP systems with the corporate ERP.
Limitations
- Complex Integration: Ensuring seamless data integration and consistency between the corporate and subsidiary systems can be complex and may require significant effort in terms of middleware or integration platforms.
- Potential for Data Silos: If not properly managed, two-tier architecture can lead to data silos, where information is not shared effectively between the corporate and subsidiary systems.
- Increased Management Overhead: Managing multiple ERP systems across different tiers requires additional oversight, resources, and expertise, which can increase the overall complexity of IT operations.
