Workflow Analysis: Work behind the Work

 

Workflow analysis is a powerful tool that delves into the inner workings of how things get done within your organization. Imagine it as shining a light on the invisible pathways tasks take, revealing inefficiencies and opportunities for optimization.

 

At its core, workflow analysis is the meticulous examination of the sequence of tasks, decisions, and handoffs that make up a specific business process. It's like peeling out multiple layers of the task and examining the steps involved in it.

 

Example:

Imagine a busy restaurant kitchen.  During peak hours, orders fly in, ingredients need prepping, and meals need to be cooked and delivered to tables efficiently.

 

Workflow analysis in this scenario would be like observing the following:

• The Sequence of Food Preparation: You'd track the steps involved in each dish, from receiving ingredients to plating and sending it out. Are vegetables chopped efficiently? Do servers wait too long for food to be plated?
• Handoffs and Communication: You'd examine how information flows between cooks, prep staff, and servers. Are orders communicated clearly? Are there any delays due to misunderstandings?
• Movement of Staff and Materials: You'd observe how cooks move around the kitchen, how ingredients are transported, and if there's any unnecessary movement causing delays. Are cooks constantly bumping into each other? Do ingredients need to travel long distances before reaching the cook who needs them?

By analyzing the workflow, you might identify areas for improvement, such as:

 

• Redesigning the layout of the kitchen to minimize unnecessary movement.
• Implementing a standardized plating system to speed up the final food assembly process.
• Introducing a digital ordering system to streamline communication between servers and cooks

This will eventually result to a more efficient kitchen where food gets prepared faster, mistakes are reduced, and customers are served promptly, leading to happier staff and satisfied diners.  This is the power of workflow analysis in action!

 

Workflow Analysis: The Spotlight for Continuous Improvement with DMAIC

 

1. Define:

 

Problem Identification: During the Define phase, workflow analysis helps identify areas for improvement. For example, analyzing the order processing workflow might reveal delays due to manual data entry or missing information.

 

2. Measure:

 

Metrics Selection: Workflow analysis aids in selecting the right metrics to measure process performance. In the order processing example, metrics could include order processing time, error rate, and customer satisfaction scores.

 

3. Analyze:

 

Root Cause Identification: Workflow analysis helps pinpoint the root causes of process inefficiencies. By examining the order processing workflow, you might identify repetitive tasks, unnecessary approvals, or lack of communication between departments.

 

4. Improve:

 

Process Redesign: Based on the analysis, workflow analysis informs the redesign of the process for improvement. For example, automating data entry, streamlining approvals, or implementing a communication system could improve order processing efficiency.

 

5. Control:

 

Monitoring and Sustaining Change: Workflow analysis helps monitor the effectiveness of the implemented changes. By tracking order processing metrics after the redesign, you can ensure the changes lead to sustained improvement.

 

Example:

 

Workflow analysis of customer invoice processing process:

 

Workflow Analysis: By mapping the invoicing workflow, they might identify redundant steps, manual calculations prone to errors, and slow communication between departments.

DMAIC Integration:

• Define: Identify delayed and inaccurate invoices as the problem.
• Measure: Track invoice processing time, error rate, and customer complaints.
• Analyze: Using the workflow analysis, pinpoint root causes like redundant steps and manual calculations.
• Improve: Automate repetitive tasks, implement data validation, and improve communication.
• Control: Monitor invoice processing metrics after implementation to ensure improvements are sustained.

By integrating workflow analysis with DMAIC, companies can create a structured approach to process improvement, leading to increased efficiency, reduced errors, and improved customer satisfaction.

Workflow Analysis:

Imagine you're in the kitchen making your morning coffee. You know the routine: grab the mug, fill the kettle, wait for it to boil, add coffee and hot water. But what if you decided to analyze this workflow? Workflow analysis is exactly that – taking a close look at the steps involved in a specific task or process.
 

Think of it like examining the inner workings of a machine. You identify each cog and gear, how they interact, and if there's any friction slowing things down. In the business world, workflow analysis examines the steps employees take to complete a task, like processing an order or handling a customer complaint.

How it's integrated in DMAIC's each step:

1. Define: This is where you identify the specific workflow you want to improve. Maybe it's the process for approving marketing materials, or handling customer returns.
2. Measure: Here's where you gather data on how the current workflow is performing. How long does it take to approve materials? How many returns get stuck because of missing information?
3. Analyze: This is where the workflow analysis shines. You use the data from the "Measure" phase to identify bottlenecks, delays, or unnecessary steps. Think back to our coffee-making example. Maybe you realize you always forget to turn on the kettle before grabbing your mug, adding an unnecessary wait.
4. Improve: Based on your analysis, you brainstorm solutions to streamline the workflow. Maybe you could move the kettle closer to the mug, or set a phone timer as a reminder.
5. Control: Once you implement your improvements, you need to monitor their effectiveness. Did the new mug-kettle placement save time? This helps ensure the changes actually make a difference.

A Real-Life Example

An insurance company struggling with processing claims. Their current workflow involves a lot of back-and-forth between adjusters and doctors for approvals, leading to delays for customers.

Using DMAIC, the company could:

• Define: Identify the claims processing workflow as the target for improvement.
• Measure: Track the average time it takes to process a claim, and identify where delays occur.
• Analyze: Workflow analysis might reveal unnecessary steps like redundant paperwork or unclear communication channels between adjusters and doctors.
• Improve: They could streamline the process by implementing an online approval system, reducing paperwork, and establishing clear communication guidelines.
• Control: Monitor the new process to see if claim processing times have improved, and make adjustments if needed.

By combining workflow analysis with the DMAIC framework, companies can identify inefficiencies and implement targeted improvements, leading to faster processes, happier customers, and a smoother-running business. It's all about taking a step back, examining the inner workings of your workflows, and finding ways to make them work smarter, not harder.

What is workflow analysis?

Workflow is a group of tasks followed in particular sequence whereas workflow analysis is defined as path to improve efficiency. It is the process through which improvement area and process hurdles are to be identified.

Workflow analysis steps:

Analysis steps depend on business to business. However, broadly it can be performed via asking four questions.

(1)   What do we do?: In this steps we identify core steps that performed from beginning to end.

(2)   How do we do?: In this steps processes are identified for each core steps.

(3)   Why do we do?: In this steps, needs to be identified and importance of each steps to be calculated.

(4)   What does each department do?: In this steps, significance and activities performed by each department are identified.

Based on above questions and answers, inefficiencies in workflows are identified and improvement steps are to be confirmed.

In DMAIC approach,

(1)   Define: Value stream mapping is used to map entire process. Workflow analysis can be done to optimise each step and problem can be defined efficiently.

(2)   Measure: Data recording to capability analysis activities can be done efficiently through workflow analysis and optimization.

(3)   Analyse: Validity of route cause can be done via RCA and FMEA. Workflow sequence can be optimised which includes discussion between cross functional group.

(4)   Improve: Documentation workflow includes what changes are made and why it is implemented as well as impact on improved process can be harmonized.

(5)   Control: Final documents preparation with control strategy which includes multiple signing from cross functional team.

Example:

(1)   EDMS: Electronic Document Management System: During document preparation, review and signing, particular workflow is followed. To manage this workflow, EDMS can be used which flows document from one department to another department sequentially.

(2)   iLIMS: When there is OOS (out of specification) or OOT (out of trend) data generated then investigation initiated. iLIMS is used to manage all workflow from identification to CAPA implementation which links all inter department documentation.

(3)   Solvexia: It is one of software which can help to automate workflow of code and data management. Thereby it improves productivity.

Workflow Analysis is one of the key methods of mapping the process flow and opportunities within that can be used to identify and drive a project. It can be mapped to DMAIC phases in the following manner:

 

Define : Through workflow analysis we can identify the opportunity which can be further utilized to develop the project along with the SIPOC which gives a high level view of the workflow.

 

Measure: Using the workflow analysis here helps identify the points from where the data related to potential causes can be identified along with the right function/tool from which data can be taken.

 

Analyze: The data collected through opportunities in workflow analysis along with the right causes that impact the project aim are identified and provide the right direction towards workflow improvement

 

Improve: In this phase, the actions from key causes identified from Analyze phase are designed and here the controls identified in Workflow Analysis are further improvised and in certain cases new controls can be implemented to make the process more robust and reduce variation in the process output

 

Control: In order to ensure that the controls have been effective, the control action deployed in Improve phase are monitored for which the right data is provided through the data sources identified in Workflow Analysis are utilized.

 

 

Workflow analysis is a methodical study of different tasks and processes within a company to identify  redundancies and opportunities for improvement. The primary goals are to enhance productivity, reduce costs, improve quality, and compliance .

 

Define : If a hospital wants to reduce patient waiting times. Workflow analysis is used to document the existing patient intake process, from registration to seeing a doctor, Which helps to pin point exactly where the error has occurred.

 

Measure : In the hospital example, data on patient waiting times, registration processing times, and the time taken for initial assessments are collected. Workflow analysis helps in determining these specific metrics and their sources.

 

Analyze : Analysis of the hospital’s workflow reveals that the delay occurs during the patient registration process due to redundant paperwork and inefficient data entry procedures.

 

Improve : The hospital redesigns its patient intake process by introducing a digital registration system that pre-fills patient information and reduces paperwork. Workflow analysis helps in designing this new process and assessing its impact on waiting times.

 

Control : The hospital sets up a monitoring system to track patient waiting times and registration processing times on an ongoing basis. Workflow analysis helps in determining the (KPIs) to monitor and the best points in the workflow to collect this data.

 

 Workflow analysis is a critical tool within the DMAIC framework, providing a detailed understanding of processes and enabling targeted improvements. By integrating workflow analysis into each phase of DMAIC, organizations can achieve sustainable and continuous improvements in efficiency, quality, and overall performance.
