DMAIC Project CharterText

ABC Soft is facing many angry customers for the past 6 months. More than 40% of their projects are delayed.

to reduce the schedule variance from 40% to less than 10%.

This will save the company an estimated USD 500,000 every year.

In scope:All the projects received from US in the Pune office.

Out scope: everything other than the above.

Mr A, B, C and DResources: Internet ,

Tip: First start with Outputs and Customers. Next set process boundaries and do the process map steps and then list inputs and suppliers

Moments of Truth (MOT):Any time a customer draws a critical judgement, positive or negative, about the service, based upon a service experience (or lack of it).Value-Added (VA):• Is the customer willing to pay for it?• Is it done right the first time?• Essential work that moves one step closer to the

final product.Value-Add Enabler: step that is required to do VA

Non-Value Add (NVA):Steps considered non-essential to produce and deliver the product or service to meet the customer’s requirements. The customer is NOT willing to pay for the step.

ROOT CAUSE ANALYSIS Estimation method not used. No training provided for Estimations.

QUANTIFYING THE GAP/OPPORTUNITY The opportunity that the problem is going to happen (92) because of Estimation method is not used. The opportunity that the problem is going to happen (74) because there is No training provided for Estimations.

Criteria are the requirements that you want your solution to meet. Some criteria are “must” criteria. Any solution that does not meet even one of the “must” criteria must be eliminated

Where weight and scores on following scale : High = 9, Medium = 3 and Low = 1.

• Solution A = Estimation methods should be tested and calibrated to our organization using our own past projects and determining the methods’ accuracy level. • Solution B = Provide training as well as Motivate and educate our estimators about how important is the training for estimations.• Solution C = Accuracy is correlated with training and the ability to see results, not development experience.

The methods are primarily based on data from past projects. Researchers studied project data and determined equations and formulas that best matched the existing data points. Some of the formulas are extremely simple, others are complex. None are totally accurate with all of the past projects, nor should you expect them to be with their predictions for future projects. Instead, they predict, based on their formulas (which are primarily based upon their data set), Estimators estimate the same project using the different estimation methods and models. Their results vary widely, depending on their definition of the project, their assumptions, and the models used. Finally we should use three things :-• Expert opinion with analogy .• Algorithmic models .• expert opinions by experts with different project experiences and responsibilities .

Improving your estimation skills, processes, and how you communicate your estimations will help you avoid the difficulties inherent in estimation; however, your ability to estimate well will always be limited by the extent of your projects‘ uncertainty.
