Integration of Enterprise Systems

We have discussed the advantages of businesses having access to enterprise-wide data and information.  These include increased efficiency, better decision-making, improved customer service, potential cost savings, and increased agility.  There are several strategies to achieve integration of information within an enterprise.  A company may choose to use an Enterprise Resource Planning (ERP) system, which provides an off-the-shelf integrated software solution. 

Another strategy is to attempt to integrate the data from independent, stand-alone systems.  This strategy is often preferred in companies with existing, or “legacy” systems, that are well established in existing workflows and processes.  This approach can be technically challenging, however, and should be adopted with caution. 

Finally, companies may choose to use existing and/or stand-alone systems and integrate the most important information from these systems by hand.  Each of these approaches will be discussed below.

Integrated Information Systems

Enterprise resource planning (ERP) systems provide an off-the-shelf, integrated platform for managing all the core business processes like finance, HR, supply chain, customer relationship management, etc. One of the essential functions of ERP is to facilitate the integration of data from various departments and functional areas of the organization. The following are the advantages and disadvantages of integrating enterprise data in comprehensive ERP systems:

Advantages:

Provides a unified view: ERP integration enables the organization to gather data from various sources and integrate them into a single system, which provides a unified view of the business in real-time. This allows the management to make informed decisions, and employees to access accurate and consistent data.

Increases efficiency: Integrating enterprise data in ERP systems helps to streamline business operations, automate repetitive tasks, and reduce manual errors, thereby increasing productivity and efficiency.

Improved data quality: ERP systems provide an integrated database for all the data, which ensures data consistency and accuracy, thereby improving the quality of data.

Enables informed decision-making: With data integration, businesses can make informed decisions based on real-time data, which leads to better decisions that drive growth and market leadership.

Potential Disadvantages:

High implementation cost: Integrating enterprise data in ERP systems can be a costly affair that requires expert assistance, additional hardware, and software licenses.

Technical expertise required: Integration of data from various sources requires technical expertise, which may not be available within the organization, requiring additional expertise to be sourced externally.

Resistance to change: Resistance to change is common among employees who have been using legacy systems or manual processes for years. Therefore, it requires a lot of time and effort to train employees to use the new system, which can impact productivity and revenue.

Security threats: As the data is integrated from various sources, there is a risk of data breaches or unauthorized access, making it crucial to have proper security measures in place.

In conclusion, the integration of enterprise data in comprehensive ERP systems provides an excellent opportunity for businesses to streamline operations, improve efficiencies and decision-making, and reduce errors. However, there are some considerations and challenges to be overcome, especially in terms of cost, technical expertise, resistance to change, and security.

Integrating Stand-Alone Systems

Businesses may choose to extract and use information from a variety of stand-alone, or independent, information systems.  This is often a choice when a company is invested in one or more “legacy” systems that perform some functions well but are not integrated with other systems in the enterprise.  Integrating stand-alone systems can have advantages, but integration is fraught with challenges and risks.  Here are some reasons an enterprise may choose to integrate information from multiple independent systems:

Cost efficiency: Using independent information systems for different departments can be cost-effective as each department can choose the system that best fits their needs and budget.

Specialization: When each department has its own information system, it can specialize in the collection, processing, and analysis of the specific data it needs to make decisions.

Flexibility: Using independent information systems provides flexibility for different departments to customize their systems to fit their unique needs.

Integration Challenges

Technical Complexity: Integrating multiple independent information systems involves a lot of technical complexity as data is often located in various formats, databases, and applications which have to be compatible with each other. The integration process demands expertise in new technologies to ensure the effective functioning of systems.

Data Complexity and Quality: Combining data from various information systems, particularly ones from different vendors, can result in data complexity and quality challenges. Data formats may differ, and data values may conflict, resulting in discrepancies and uncertainty about the accuracy and completeness of the integrated data.

Integration Costs: Integration implementation can be very expensive, especially when there are various systems with differing architectures and technologies. Software and hardware acquisition, maintenance, and licensing can also add to the costs.

Security and Privacy Risks: Integrating multiple information systems can increase an organization’s security vulnerabilities. As various systems will now be interconnected, cyber-attacks, data breaches, and unauthorized access risks are a significant threat.

Change Management: Integrating systems requires significant changes to an organization’s processes, procedures, and workflows, as data sharing will be across departments and systems. This makes merging data even more challenging, as employee training must be undertaken to ensure the new system is appropriately used.

Interoperability: It is essential that the integrated system operates efficiently, and the various systems must be able to share data and communicate with one another. The lack of interoperability between systems can hinder successful integration efforts.

In summary, independent systems, particularly legacy systems, may provide advantages to the organization.  Legacy systems may be a part of existing processes and workflows, with users accustomed to using them.  The company may see the investments in existing systems as a reason to keep using them.  However, there are significant technical and financial risks involved in attempting to integrate information from a variety of systems.  Companies should use care when choosing this as its information management strategy.

Manual Integration of Information Systems

Integration of essential information from independent systems within an organization can be a challenging task, especially if there is no common data format or protocol for communication between different systems. However, companies, particularly small businesses, can adopt manual integration techniques to overcome this challenge, particularly if a only a small set of essential data can be identified. Some of the techniques that can be used to manually integrate essential information from independent systems are:

Data entry and validation: One of the simplest methods of manually integrating data is to copy the required data from one system and manually enter it into another. Before entering the data, it is important to validate it for accuracy and completeness to ensure that it is useful in the new system.

Data transfer via CSV or Excel files: Another method to manually integrate data from independent systems is to export data into a CSV or Excel file from one system and then map and import it into another system. This method is useful when the data does not have complex relationships.

Screen scraping: Screen scraping involves extracting data from a system by reading and interpreting data displayed on its user interface. This is a useful technique when there is no other way to extract data. However, it can be slow and may require regular updates if the source system changes.

Manual mapping of data: Manual mapping involves analyzing the structure of data in the source system and creating a mapping document that maps the data to the destination system. This method is useful when the systems have complex relationships and hierarchies.

In conclusion, manual integration techniques can be used to integrate essential information from independent systems within the organization. However, this can be a resource-intensive effort so it is essential to choose the right technique based on the complexity of the data, relationships between systems, and the available resources.
