Why Because Analysis is a technique used to identify / analyze the root cause of the unexpected failures / behavior of systems. It’s also know as WBA a method of causal analysis. This analysis is conducted by to determine the root cause of the problem or accident by repeating the questions “Why” using 5 Why Because analysis. WBA analysis can be used for technical and socio –technical systems. Basically can be used in variety of system domains. Technical analysis covers the analysis performed on the accidents occurred in various industries like Aviation, Marine, Railway, Industries. Socio Technical system like Courts, Academia, Agriculture, Public Finance etc. This analysis can be visually represented by drawing a tree diagram which includes cause – effect relationship between factors. These casual factor are represented as node. This graphical representation is also known as WBG – Why Because Graph. This provides a clear understanding of what led to an accident or incident. Graph looks like below. Technical Example: Big and longest Analysis – Titanic failure

ABC analysis is a technique in an inventory management which helps in classifying the value of inventory items based on their criteria or the importance of the products to the business. Three main criteria’s on basis of which they are classified are demand, cost and risk. Store Managers or Inventory Managers group these items into different classes based on the above criteria. This also helps company to understand the most successful product which is in demand and contributes highest in profit sharing of the business. This is also known as Always Better Control, as this analysis helps to have sufficient stock as per the demand and thus helps companies to earn profit with a systematic and calculative way. Now let’s see how it is calculated? Multiply the annual sales of specific item by its cost, this will give the status of products which needs are high on demand and needs to be stocked; also will help to analyze the products which yield less profit. Accordingly company can take a call on having structured approach. Number of items sold in a yr. X Cost per item = Annual value of sold product After identifying the value of each product with the help of Pareto Analysis i.e with 80/20 rule, it will be easy to conclude the ranks and can accordingly place them under the classes made which is “A”, “B”, “C” Let’s identify Strengths v/s Shortcoming with the help of an example; Categorize the inventory (products) according to the value and importance. Company: Dettol High valued items in class “A” – Disinfection products >> Sprays, Handwash, Soaps, Floor cleaners etc Average valued products in class “B” – Antiseptic products >> Original Dettol liquid, Least valued material in class “C” – Band aid / Handplast, Skin care products, Bandage
