TOP LABSGET LEANGIVE YOUR LAB THE EDGEMANAGEMENT BRIEFINGEFESO Consulting / BSM has developed Lean methodologies and solutions specific to the Lab environment which substantially improve measurable performance and/or reduce lead-times & costs.Most analytical and microbiological labora-tories have relatively low volumes but a high degree of variability and complexity. Many standard lean tools are not a good fit, however Lean can and should be applied to labs. A generic approach will not work but careful adaptation of the techniques based on a thorough understanding of Lab operations will deliver significant benefits in terms of cost or speed or both.BSM has developed methodologies and solutions specific to the Lab environment which minimise non-value add activity and maximize throughput and/or velocity.Laboratories are not the same as manufacturing environments. While most of the key principles of traditional Lean still apply, there are many unique challenges involved in effectively implementing them in laboratories. tKey principles that always apply* tSpecify Value tIdentify the Value Stream tMake Value Flow & Create Pull tLevel the Load & the Mix (Heijunka) tEliminate Waste tManage Performance tApplying Lean in the LabLean in the Lab should not just be about applying techniques or developing people skills it should be primarily focused on improving measurable performance. Of course people will learn valuable new skills but firmly in the context of improving KPI’s or reducing costs.Although the basic concepts and techniques of lean are simple, adapting them to the lab situation and integrating them into a defined process that uses resources well (and is simple to manage) is quite a challenge.If a Lean project is to be successful and delivered within a reasonable time frame, it is necessary to resource it properly. This should include signif-icant senior management support and/or the use of external consultants with a relevant track record and excellent project management skills. Obviously this costs money and a clear ROI (Return on Investment) and measurable project objectives should be established prior to embarking on a full project. A company would generally have no problem investing in a new piece of equipment that could substantially improve measurable performance and/or reduce lead-times and costs. Investing in a project to achieve the same result via a Lean Lab implementation should not be any different.Improving measurable performance, reducing lead-times and costsfLean in the LaboratoryWhat we often find in Labs tLack of FocusAnalysts and Microbiologists are typically only focused on test accuracy and individual test run efficiency. Very often, personnel are dedicated to specific tests and there is little or no control of the progress of individual samples through a sometimes highly variable test routing (dependant on product type and/or intended market). tLong and variable lead timesIn many test laboratories, we find queues in front of each test in which individual samples wait until enough similar samples arrive to constitute an efficient test run. This approach causes long and variable lead times and, contrary to popular belief, does not result in higher productivity. t Ineffective ‘Fast Track’ systems ‘Fast Track’ systems are often developed in an effort to deal with urgent samples but these rarely work. In most cases, the proportion of samples designated as priority becomes so large that ‘Fast Tracking’ quickly becomes unworkable. A much better approach is to re-engineer the process to improve the velocity for every batch. It can be done! t High levels of WIPMost labs we see have high levels of WIP which inevitably results in lots of (non value adding) effort being expended in controlling, tracking and prioritising samples and in planning analyst work. Companies often respond to this situation by investing in a LIMS or other costly IT system. However these systems do not in themselves improve performance. The underlying process by which work is organ-ised and moves through the lab must first be re-engineered based on lean principles. t Volatile incoming workloadFor many labs the incoming workload is inher-ently volatile with significant peaks and troughs. This causes low productivity (during troughs) and/or poor lead time performance (during peaks).Very often the capacity of the lab is not well understood and there is no mechanism to level load the workload. The surest way to fail is to put more work into the lab than it can handle! This may seem obvious but it is remarkable how often this is exactly what happens. t High analyst turnoverThe levels of analyst turnover in Irish test labs is remarkable by comparison to other Life Science departments and to other countries. This brings a unique set of difficulties with many labs being in constant training mode. This can be made easier to manage by the ‘standard work’ approach of lean which inevitably leads to more prescribed and structured processes and roles.fAssessment t Specify ValueStart by identifying, quantifying and categorising lab activity as ‘value add’, ‘non value add’ (from the customers perspective) and ‘incidental’. Note: Incidental work is non value add in itself but essential to enable ‘value add’ tasks to be carried out.It is also worthwhile defining tasks as being ‘time elastic’ or not. This has value later in enabling level loading. A significant focus of any Lean Lab initiative will be to eliminate or reduce the non value add activities. t Identify the Value StreamDevelop value stream maps of the overall release process. This should avoid the error of working on point solutions that only end up moving a bottleneck to another process and therefore do not deliver overall improvements. For example there is no real value in reducing analytical lab lead times below a release constraint test in the Microbiology lab. You can however use increased velocity to help ‘level the load’ or to maximise individual test run efficiency. t Make Value Flow & Create PullDefine sequences of tests and associated analyst roles that make good use of people and equip-ment. Once you start testing a sample, keep going and do not let samples queue between tests. This will create a reduced ‘through-put’ time which can be converted into a lead-time reduction or used to allow samples to wait in an incoming queue to facilitate level loading and /or grouping for efficiency. Interpret ‘Pull’ as testing according to customer priority. If this is not inherent in the order in which samples arrive, launch samples from an incoming queue according to customer demand and thereafter process them in FIFO order with no overtaking. t Level the Load & the Mix (Heijunka) At its simplest, levelling the load (overall workload) and the mix (the mix of sample types) is about putting the same amount of work into the lab on a daily basis. This is probably the most critical step and potentially the most beneficial for the majority of Labs. Successfully levelling a volatile load and mix will significantly improve productivity and/or lead time. The productivity improvement can be used to provide additional capacity or converted into a cost reduction.Level loading can be achieved using queuing time created by reducing the through-put time and via the time elastic tasks identified when ‘specifying value’. t Eliminate WasteDevelop solutions and re-engineer processes to eliminate or reduce the non value add and incidental tasks identified when ‘specifying value’. Use visual management techniques to signifi-cantly reduce work planning effort. Ban all Excel trackers! t Manage PerformanceDevelop a structured performance management process which includes a review of lab perfor-mance on a daily basis. This can be in the form of ‘huddles’ i.e. short ‘stand up’ meetings held at a team white board. The agenda should be the same every day – basically how was yesterday, what is the plan for today, what actions do we need to take.Applying Lean in the Lab – key principles that always apply“Applying Lean in a Lab is always challenging but, if done properly, the results can be extraordinary.”fImplementation tGetting StartedBefore embarking on a Lean Lab project, you should carry out a structured appraisal of the ‘as is’ situation. tAssess current processes and measurable performance. tIdentify and size opportunities for improvement via the application of lean techniques. tDecide ‘go’ or ‘no go’ based on the potential ROI of an implementation project.Figure 1: One of the Typical Outputs of an Assessment tWhat we often find in Labs* tLack of Focus tLong and variable lead times tIneffective ‘Fast Track’ systems tHigh levels of WIP tVolatile incoming workload tHigh analyst turnoverff*FURTHER DETAILS OVERLEAFwww.leanlaboratory.comPRODUCTIVITYLEAD TIMEQUALITYPERSONNEL WITHTEST ROLESEARNED HOURSPERFORMANCEVALUE ADDEDWORKBATCHES WITHINTARGET LEAD TIMELEAD TIME VS RATELIMITING STEPAVERAGE DAYSVS TARGETDOC RFTTESTINGRFTOOSCLOSUREEFESO Consulting brings more than 35 years’ experience and thought leadership, supporting many of the leading global brands in both mature and emerging markets.EFESO Consulting is a group of over 400 experienced consultants representing 45 nationalities.
