Britest Lite

1. Purpose 

The Britest Lite approach is useful for using Britest tools in a less formal context than in a full Britest study. It will  usually involve fewer people for a shorter space of time and focus on a specific problem using one or two specific Britest tools. The use of Britest Lite can often help to identify when a full Britest study is required.

A typical Britest Lite session

• Involves 1 to 6 people
• Takes between 30 minutes and 3 hours
• Rarely requires independent facilitation

It is useful for

• Experimental planning
• Troubleshooting
• Facilitating small team discussion

The benefits of this less formal application of Britest tools include

• Structuring thinking
• Capturing known/unknown/assumed information
• Representing knowledge in visual format/model
• Recording thought processes for corporate memory

2. Methodology

1. Start with ISA	Problem definition for troubleshooting Agree assumptions and constraints
2. Choose tools to meet the agreed onjective	See examples of Britest lite application of tools below May also include, e.g. 5 Whys, Ishikawa (Fishbone) diagrams

3. Examples of Britest Lite application of tools

3.1 Rich Pictures and Cartoons

• Experimental set-up
• Thinking through physical issues at different scales
• Addressing issues of localised materials distribution  (mixing, local concentration effects, local hot spots etc.)

3.2 Transformation Maps

• Experimental design (e.g. order of addition)
• Helping identify likely/actual impurities
• Structuring thinking around operating strategy
• Identifies if full Driving Force Analysis is required

3.3 Process Definition Diagrams

• Mapping process to plant 
• Facilitating chemist/engineer/plant discussion during process development
• Operator training
