Efficient Data Import Strategies for Your New CMMS

Share this page:

CMMS helps companies maintain their assets, equipment, and facilities more efficiently by providing a centralized platform for tasks such as work order management, asset tracking, preventive maintenance scheduling, and performance analysis. Importing data correctly plays a pivotal role in successfully implementing and utilizing a CMMS.

When an organization implements CMMS software for the first time or transitions to a new system, it often has a lot of existing data, including equipment records, work order history, inventory and parts data, and employee details. Importing this data into the CMMS accurately is a critical step. Without proper data import, a CMMS may start with an incomplete or inaccurate database, hindering its ability to deliver on its promises of improved maintenance efficiency, cost savings, and data-driven decision-making.

Efficient data import allows organizations to kickstart their CMMS with a robust foundation of historical and current information. This empowers maintenance teams to optimize workflows, plan maintenance activities, monitor asset performance, and reduce downtime. It also ensures the CMMS delivers accurate insights and reports, aiding in better decision-making and compliance tracking. 

Depending on the volume and reliability of records, importing data can be daunting and complicated, and many organizations face challenges during this process. Numbers vary, but some reports show that 50-80% of CMMS implementations fail, and data migration is one of the main pain points. In this article, we aim to demystify the process of importing data by covering preparation and choice of methods for validation and maintaining data integrity and quality. The ultimate goal is to help our readers have a successful CMMS implementation and avoid being another statistic.

Preparing Your Data for Import

1. Data Cleaning and Validation

Before you embark on the journey of importing data into your new CMMS, it is important to dedicate time and effort to data cleaning and validation. This preparatory phase is often underestimated but is fundamental to the success of your CMMS implementation. The following are key steps of data cleaning and validation:

1.1 Removing Duplicates

Duplicate data in your CMMS system can lead to confusion, inefficiency, and potential errors in maintenance activities. To eliminate duplicates:

  • Conduct a thorough scan of your data sources to identify duplicate records.
  • Decide on a strategy for handling duplicates, such as merging them, retaining the most recent entry, or flagging them for manual review.
  • Use data cleansing tools or scripts to automate the removal process wherever possible. 
  • Maintain a record of duplicate removal actions for reference.

1.2 Standardizing Data Formats

Inconsistent data formats can hinder data import and future data analysis. Standardization involves:

  • Ensuring that data, such as dates, measurements, and naming conventions, follows a uniform format.
  • Using data transformation tools to convert data into the required format for your CMMS. 
  • Creating a data format guide for your team to follow to maintain consistency in data entry after import.

1.3 Ensuring Data Accuracy

Accurate data is the bedrock of any CMMS. To enhance data accuracy:

  • Implement validation rules to flag or correct erroneous data during the import process.
  • Conduct data verification checks against source documents, physical inspections, or other reliable references.
  • Involve subject matter experts in the data validation process to verify technical details and ensure precision.
  • Establish data accuracy benchmarks and continuously monitor and improve data quality post-import.

2. Data Organization

Successful data organization is essential for an effective CMMS implementation and involves three main aspects of data organization: categorizing data types, mapping data, and determining data sources.

2.1 Categorizing Data Types (e.g., Equipment, Work Orders, Spare Parts)

One of the first steps in preparing your data for import is to categorize it into distinct types or classes. In the context of a CMMS, this typically includes, but is not limited to:

  • Equipment: Such as machinery, vehicles, or tools.
  • Work Orders: Details about maintenance or repair tasks.
  • Spare Parts: Inventory information about replacement parts and supplies.

Categorization serves several purposes:

  • It helps you identify and prioritize which data sets to import first.
  • It enables you to define relationships between different data types, which can be essential for CMMS functionality.
  • It ensures that you're importing data relevant to your maintenance processes.

2.2 Mapping Data

A data map is like a roadmap that guides you through the process of data import. It involves documenting the structure and relationships between your data categories. Here's how to create an effective data map:

  • Identify the key fields within each data category (e.g., equipment name, maintenance date, supplier details).
  • Determine how these fields relate to each other (e.g., which equipment is associated with specific work orders).
  • Visualize these relationships using diagrams or flowcharts to better understand data flow within your CMMS.
  • Use the data map as a reference during the import process to ensure that data is imported correctly and linked appropriately.

2.3 Determining Data Sources

Knowing where your data resides is essential for a smooth import process. Your data sources may vary, including:

  • Existing databases or spreadsheets
  • Legacy CMMS systems
  • Paper records or manuals
  • Vendor databases or equipment specifications
  • Third-party systems (e.g., accounting software, ERP, procurement systems)

To determine data sources:

  • Conduct a comprehensive inventory of all potential data repositories.
  • Assess the quality and completeness of data in each source.
  • Identify data owners or custodians who can provide access and assist with data extraction. 
  • Consider data extraction methods, such as exporting from databases, converting file formats, or using data migration tools.

Choosing the Right Data Import Method

Selecting the right data import method hinges on your organization's specific requirements, existing infrastructure, and long-term objectives.

Each method has its own set of advantages and disadvantages, and your choice should align with your organization's unique needs and resources. The following are six common data import methods and their pros and cons:

Data Mapping and Field Matching

1. Defining CMMS Fields

Before you can begin mapping your source data to your CMMS, it's essential to have a clear understanding of the CMMS fields you'll be working with. CMMS fields are the specific data points or attributes your CMMS uses to organize and manage maintenance-related information.

Common CMMS fields include equipment name, asset ID, maintenance date, work order description, and more. Begin by creating a comprehensive list of all the fields within your CMMS that will be involved in the data import process. This will serve as your reference guide when mapping source data.

2. Mapping Source Data to CMMS Fields

Once you've defined the CMMS fields, the next step is mapping your source data to these fields. Mapping is the process of associating each data point in your source data with the corresponding field in your CMMS. This ensures that the information is correctly placed within the CMMS database.

To do this effectively:

  • Identify the equivalent field in your source data for each CMMS field.
  • Ensure that the data types match (e.g., date fields in source data align with date fields in CMMS).
  • Consider data transformations if source data requires conversion or modification to match CMMS field formats.

3. Ensuring Consistency in Data Mapping

Consistency in data mapping is essential to avoid confusion and errors during the import process. 

To maintain consistency:

  • Document your data mapping decisions clearly and comprehensively.
  • Create a standardized naming convention for fields and their mappings.
  • Establish clear guidelines for handling ambiguous or missing data in source files.
  • Consistency simplifies the initial import and makes future data maintenance and updates more manageable.

4. Handling Custom Fields and Data Transformations

In addition to standard CMMS fields, you may have custom fields or data transformations to consider. Custom fields allow you to capture specific information that's unique to your organization's maintenance processes.

When mapping custom fields:

  • Define the purpose and usage of each custom field.
  • Ensure that your source data contains corresponding data for these custom fields.
  • Map custom fields to their respective locations in the CMMS.

Data transformations may be necessary to convert data from one format to another. For instance, if your source data represents dates differently from your CMMS, you must create rules or scripts for this conversion.

Data Import Best Practices

Following best practices during the data import stage can help ensure a smooth and successful data migration. Here are some key best practices to consider:

1. Backing up Your CMMS Database

Before you initiate any data import, you should back up your existing CMMS database. This precautionary step is vital to safeguard your existing maintenance records and configurations.
