Project management for manufacturing: the five stages of planning
Using project management for manufacturing is a great way to manage your time and resources efficiently while making sure you reach your goals in an efficient manner.
Manufacturing batch records are crucial documents for verifying quality in chemical and process manufacturing. Here’s everything you need to know about them.
There is an old saying used in the Food and Drug Administration and other compliance organizations:
If it isn’t written down, it didn’t happen.”
In the pharmaceutical manufacturing industry, this is especially true. Documentation is critical if a company is to follow current good manufacturing practice (cGMP) regulations. Batch manufacturing records (BMRs) are an important part of that documentation process.
However, maintaining complete and accurate BMRs can be challenging without the proper systems in place. Below, we’ll walk you through the different types of documents that you should be creating, why they are important, and what is included in each.

In pharmaceutical manufacturing, a batch is defined by the FDA as “a specific quantity of a drug or other material that is intended to have uniform character and quality, within specified limits, and is produced according to a single manufacturing order during the same cycle of manufacture.”
For example, a company that is producing 100,000 pills of a certain medication would consider the entire 100,000-pill run to be one batch. Each pill is expected to be identical to the others in terms of the active ingredient, strength, and other specifications.
A batch record is a comprehensive set of documents that outlines all aspects of the manufacturing process for a particular batch. It includes details about ingredients and supplies used, equipment settings, personnel involved, test results, and more.
There are a few titles for these records that often are used interchangeably:
However, each differs slightly in scope and function, so it is critical to understand the differences.
This is the most comprehensive type of batch record. It includes all the data associated with the manufacturing process, from raw materials to finished products. This is used to track and document each step in production, including any deviations that occur along the way.
Essentially, it is a roadmap and a ledger for the product’s journey from raw ingredients to finished goods. It is instructional, serving as a guide for manufacturing the product.
A BPR is a subset of the BMR. It includes only information about the production, such as equipment settings and personnel involved. This record is used for tracking and documenting results rather than providing instructions for how it should be done.
A BPR checklist will contain:
Unlike a BMR, this is not a roadmap but a log of the product’s actual manufacturing journey. It documents what happened, not what is planned.
An MPR is the highest-level batch record. It is a master set of instructions that outlines how the product should be manufactured, including all steps and processes. This document serves as a template for creating BMRs and BPRs for each batch produced.
It will include things like:
An MPR is an important document to have on file, as it serves as a starting point for all future batches. It ensures that each batch is manufactured consistently according to cGMP regulations.
Batch records are important for a few reasons:
They also serve as a reference for future production, guiding how to replicate the same outcome.
Every BMR, when properly formatted, should include the following sections:
This section should include the start and completion dates of the batch, as well as any other milestone dates. These are important for tracking the progress of the batch and ensuring that it is completed on time.
All raw materials used in the batch should be listed in the bill of materials (BOM), including ingredients and packaging components. This is to ensure that each component meets cGMP batch record requirements and is suitable for use.
This is an overview of the steps taken to complete the batch, from mixing and blending ingredients to packaging and labeling. Any deviations from the standard procedure should be noted here.
At the end of each step in the process, a qualified person should sign off on it. This is to confirm that they have inspected and approved the work done at that stage.
Any potential hazards associated with the product should be noted here. This could include allergens, contaminants, or anything else that may cause harm to those consuming the product.
If personal protective equipment (PPE) is needed, that should also be listed in this section and worn as appropriate.
A list of all the equipment used in the process should be included. This is to ensure that all machinery and tools are up-to-date and properly calibrated for optimal results.
This section details all tests that are to be performed on the product. It should have instructions on
After they are complete, the results will also be noted here, with any significant outliers highlighted.
Any maintenance and cleaning tasks that are carried out during the batch process should be noted here, as well as any unexpected maintenance issues. Dates, personnel, and other details should be included.
Expected and actual yield from each step in the production process should be listed here. This is important for tracking the efficiency of the process and ensuring that there are no unexpected losses.
This section should include the type of packaging used, along with any labels and instructions. Documentation for any special packing requirements should also be included.
This section defines the terms used throughout the BMR. This is to ensure that everyone involved in production understands the same language and processes.
This is a timeline of any changes that have been made to the batch during production. This helps to ensure that all variations are tracked and accounted for.
The name, identification number, and quantity of the batch should be included in this section. This helps to ensure that each batch is traceable and that any issues can quickly be identified and resolved.
Finally, this section should include any documentation related to compliance with batch records GMP regulations. Approval signatures and materials from third-party testing should be included.
Most batch records examples are presented in a tabular format. This makes it easy to compare data from different batches and quickly identify any potential problems or areas for improvement.
Some software programs can generate BMRs automatically, saving time and reducing the risk of errors.
The person responsible for preparing the BMR will depend on the size and structure of the company. In smaller companies, it is usually a designated individual or team. In larger companies, there may be separate teams for each department involved in production (e.g., quality control, operations).
Regardless of who prepares them, all personnel involved in producing a batch should review and sign off on their accuracy before they are submitted to regulators. This helps to ensure that all cGMP regulations are being met.
Enterprise resource planning (ERP) solutions can help streamline the process of creating, tracking, and managing batch records. This helps companies stay compliant with cGMP regulations by providing comprehensive documentation that is accessible from anywhere.
It also provides real-time visibility into production operations, which allows for more efficient decision-making and better control over quality. Additionally, it can be used to generate reports on performance metrics or data trends to make informed improvements to the production process.
Without batch manufacturing records, it would be impossible to ensure the quality of a product. When it comes to pharmaceutical manufacturing, quality can be quite literally a life-or-death scenario.
BMRs are the foundation of a successful production process, and software solutions can help to streamline the process and ensure that all records are accurate and up-to-date.
