CMMI Appraisals – Tester’s Journey as an Appraisal Team Member (ATM)

CMMI Appraisal

Personal Note: It’s a great opportunity for any QA/Tester to be a CMMI Appraisal Team Member (ATM). ATM gets an extensive exposure of a complete CMMI model. If your organization is going for appraisal and if you get an opportunity to be an ATM, grab it. It’s an achievement that you will like to add on to your resume.

To Readers: Appraisal is a complex and time taking process. However, I have tried to describe it as simple as possible. This article will give you a brief idea about CMMI Appraisal. It’s not about CMMI model but it will explain what happens during appraisal! There may be understanding problems initially (If you are not familiar with CMMI terminology) but, until you arrive at an example below, Please keep reading until then.

What You Will Learn:

What is CMMI Appraisal?

An appraisal is an activity that helps us to identify the strengths and weaknesses of our organization’s processes and verify how closely those processes relate to CMMI best practices.

Flash Back: When any org decides to go for a maturity level appraisal (Commonly known as CMMI Appraisal) they contact an authorized organization from Software Engineering Institute (SEI) Partner network to do the appraisal. The Authorized agency will appoint a consultant to help/guide the org to understand CMMI, creating documents and organization policies etc. This is a very long process. It starts 1 year or 6-7 months (Depending upon the maturity level of the organizational process) before the final appraisal. After preparation, LA (Lead Appraiser) will be invited to do the appraisal.

Preparation at organization level:

Before CMMI implementation, the organization has to:

ATM Journey: After Intro to CMMI course you will have Appraisal Team Member (ATM) training. LA provides training of “SCAMPI Appraisal Method Training” to ATM. After training, an exam would be held, which you need to pass. A reference document called Method Definition Document (MDD) will be provided to all the ATMs, this document describes the SCAMPI. (Topics of Intro to CMMI Training course is covered at the end of this article)

Now what is “SCAMPI”, who is “LA” and what ATM does

SCAMPI: Standard CMMI Appraisal Method for Process Improvement.

Lead Appraiser (LA): Software Engineering Institute (SEI) is an Authorized SCAMPI Lead Appraiser. (Commonly known as LA. The LA announces the final findings report and signs the Maturity Level certificate. The word certificate isn’t generally used; SEI discourages the word “certification” and instead it refers to a company as having “achieved CMMI Level 5”).

What ATM does?

ATMs support the Lead Appraisers in collecting and validating evidence for Document Review, Interview of FAR (Functional Area Representative) members and preparation of other important artifacts. (More about ATM responsibilities is mentioned at the end of this article.)

Little more about CMMI: Capability Maturity Model Integration is a process improvement model developed by the Software Engineering Institute (SEI), Carnegie Mellon University.

CMMI is comprised of a set of “Process Areas.” Each Process Area is intended to be adapted to the culture and behaviours of your own company.

There are 22 Process Areas in CMMI.                                                        

[Source: wikipedia]

Within the Process Areas in the CMMI, there are multiple “Specific Goals (SGs)” and Specific Practices (SPs).” These practices define the expected behaviours of projects and organizations.

Image: Process Area components

SG: A specific goal describes the unique characteristics that must be present to satisfy the process area.

GG: Generic goals are called “generic” because the same goal statement applies to multiple process areas.

Every ATM will be responsible for a Process Area allocated by LA to him/her. Suppose there are 22 ATMs, every ATM will have 1 process area of all the projects selected for Appraisal. Generally, LA forms a small group of ATMs. If suppose 20 ATMs are present, then the LA will create 10 groups (each group with two ATMs) and each group will be responsible for a few PA of all the projects.

Example:

Let me give an example to make you understand Specific Goal and Specific Practices and what is ATM’s role in the appraisal process.

Take an example of Process Area, Validation. (keeping in mind most of the readers here are Testers/QA’s)

Validation (VAL) is an Engineering process area at Maturity Level 3.

Purpose of this Process Area: The purpose of Validation is to demonstrate that a product or the product component fulfils, it’s intended use when placed in its intended environment.

There is two SG (Specific Goals) in this Process Area.

  1. SG 1 Prepare for Validation
  2. SG 2 Validate Product or Product Components

Let’s see Specific Practices by Goal. Specific Practices in SG1 mentioned below.

SG 1 Prepare for Validation

It is not possible to elaborate all Specific Practices here; I will consider SP1.1 to give you an idea of the appraisal process.



ATM responsibilities

Verifying Date plays an important role! Any document will be a baseline after review, so baseline date will come after review date. Similarly, the date in a checklist, review date, review point closure date will be compared; date on the respective documents should appear in a correct sequence.

I hope, now you must be having some clarity on ATM responsibility. Cross-checking all documents prepared during Software Development Life Cycle, dependency on each other followed by cross verification covers the core responsibility of an ATM. Other than this, the ATM participates in the interview of FAR members. I shall cover this topic in the future articles.

Now few more examples:

These are the generic examples to give more insight on appraisal process.

Let’s see a scenario: – While going through a weekly status meeting MoM (Minutes of a meeting) of a particular date ATM ensures on verifying two points.

  1. Risk discussed in the team meeting.
  2. One new member of the team and PM ensuring the subsequent training.

1) Risk: Risks are covered in the PA called Risk Management (RSKM).

ATM will check if this risk is mentioned in the Risk Log? If present in the Risk Log, there will be Risk Mitigation Plan or Contingency Plan? If Mitigation/ Contingency Plan are present, there may be some action item against the Plan. Now if Action item is present, would Monitoring be required? Monitoring comes under Project Monitoring and Control (PMC). ATM must have an idea about what to check and where to check.

This example shows how process areas are connected to each other and how many artifacts ATM will go through to make sure all practices are followed properly.

2) Training

All training related activity come under a Process Area called Organizational Training (OT).

Project Manager sends a request to HR department regarding training. HR will find an Internal/External trainer for the resource and conduct training. This is the general scenario, what else happens in OT?

Let’s see how OT works, suppose this financial year organization has allocated XX amount of money for training. Now HR will identify training needs, will collect the data from managers, resources and will prioritize it, along with this, HR will also identify organization’s future needs. For instance, if the organization decides to start working on communication projects along with software, either HR will hire new Resource/Managers/TL or will identify within the organization to work on this new domain.

ATM Verification Areas

For sure this is not the complete list of activity for Organizational Training; other activities are also there, these are just quotes from my memory.

Appraisal Validity: The findings and results from a SCAMPI A Appraisal are valid for a period of not more than three years from delivery of the appraisal findings. That means after every three years, organization have to go for appraisal.

Conclusion

Now see the difference in a Tester’s activity from Pre CMMI to Post CMMI.

About the author: This is a guest post by Kumar Amit Anand. The author is having more than 8 years of software testing experience in Finance and Defense domain. Having SCAMPI appraisal method training certificate, he has also participated in SEI L4 and L5 final appraisals. The author also helps his team members to understand CMMI and documentation.

I hope this was an interesting read and I appreciate if you could spare few minutes and post your valuable comments. This would help me come up with more interesting topics in the future.
