SCAMPI Phase Structure Phase IPlan and Prepare For Appraisal Phase IIConduct Appraisal Phase IIIReport Appraisal Results

Key Preparation Questions Should we have an appraisal? Should we do it now or later? Should SE and SW be appraised together with separate results, or should their appraisals be integrated? Which appraisal class should be used? What should be included in each appraisal?

Preparation Considerations Organization scope Model Scope Size Disciplines Improvement Status

Successful appraisal teams require: a plan, including objectives, constraints, scope, outputs, tailoring, resources, cost, schedule, logistics, risks, and commitment clearly defined goals clearly defined roles established rules of engagement well-defined decision procedures understanding of the group process clear communications proper team behavior balanced participation training

Decision Making - Consensus Decision making on appraisal teams is done by consensus, not unanimous vote nor majority vote Consensus is finding a proposal acceptable enough that all team members can support it or live with it, and no team member opposes it The consensus process can require several cycles through the decision cycle as the team continues to gather and analyze factual information bearing on a decision If consensus cannot be obtained, a decision should not be forced, e.g., through majority vote - the item under consideration must be left not rated

Determination of Practice Implementation The basic approach to determination of practice implementation is to: –characterize the degree to which the practice is implemented, and –note any factors which should be considered in addition as the instantiation data is aggregated (strengths, weaknesses, etc.).

Characterizing Practice Implementation -1 Assign characterization values reflecting the extent of practice implementation for each instance Aggregate practice characterizations to organizational unit level using defined method aggregation rules Iterate and focus revisions to data collection plan Generate findings based on aggregation of weaknesses and strengths

Rating Goals Goal ratings are a function of the extent to which the corresponding practices are present in the planned and implemented processes of the organization. Team judgment is used to rate goals where the objective evidence doesn’t render the outcome plainly obvious. –If all practices are FI, then the goal must be satisfied. –If all practices are NI, the goal can’t be satisfied. –The conditions between the two extremes require professional judgment.

Data Collection and Rating Concepts Corroboration –Must have direct artifacts, combined with either indirect artifact or affirmation Coverage –Must have sufficient objective evidence for implementation of each practice, for each instance –Must have face-to-face (F2F) affirmations (avoid “paper-only appraisals”): At least one instance for each practice (“one column”) At least one practice for each instance (“one row”) Or 50% of practices for each PA goal, for each project, have at least one F2F affirmation data point

Completion of Pre – Assessment Questionnaires - 1 Site Information Questionnaire –The Site Information Questionnaire helps the assessment team to rapidly understand the culture and language of the site's software practitioners and the context within which they operate Change Readiness Questionnaire –The Change Readiness Questionnaire assists an organization in determining its readiness for change

Completion of Pre – Assessment Questionnaires - 2 Organizational Structure Questionnaire –What is the real structure that gets things done? What is the communication structure? What is the relationship with the clients? How are the requirements gathered? Are there multiple customers? Are the customers internal or external? Are there end users involved? The Project Questionnaire –The Project Questionnaire is intended to help collect information for use in selecting projects or other work efforts. It helps the assessment team organize contextual background information.

Completion of Pre – Assessment Questionnaires - 3 Documented Process Questionnaire –The Documented Process Questionnaire looks at all of the documented policies, procedures, standards, guidelines, and templates as well as the artifacts that exist from the use of those defined processes and maps them to the requirements of the CMMI

Reviewing - 1 Schedule 1-2 days to review documentation – entire assessment team is present Request that “process owners” or at least process lead developers present or “walk through” the specific process area processes

Reviewing - 2 Assessment team members may ask the following questions during the presentation: –Would you please clarify or expand on a point? –Would you please jump to the referenced procedure, guideline, template, or checklist? –Would you please show project examples that have followed that procedure or used that template? –Why was this information placed in this document and not another one that is more closely aligned to the CMMI way of organization? –Would you please print a hard copy of that section of the procedure or please print out the entire procedure?

Reviewing - 3 Assessment team members can ask “interview- like” questions to gain more insight as to how these processes are actually being used on the projects Having “experts” describe their documented processes and other site assessment team members witnessing the answers eliminates or reduces the risk of long debates over the value of the documented processes in the later phases of the assessment

Consolidating - 1 Each assessment team member reviews his/her own notes and makes observations These observations may make use of the sticky note format or may simply be placed on a sheet of paper with appropriate notations that will later be shared with the rest of the assessment team After each assessment team member has had a chance to develop individual observations, the Assessment Team Leader leads or facilitates the team in a brainstorming process to get the observation candidates out in front of the team A category is picked. The facilitator asks one person to offer a strength or weakness for that category

Consolidating - 2 An observation is offered and the facilitator writes it on a flip chart or white board The facilitator asks the next person for an input: –This next person looks at what has already been placed on the flip chart or white board and what observations they have written down for themselves –If an observation already written on the flip chart or white board is close enough, they either pass to the next person or offer an observation for that category that they feel is different enough to be considered by their teammates The facilitator continues in a “Round Robin” fashion. (each person gets a turn to offer one input for a category and this process continues until everyone has run out of new ideas)

Consolidating - 3 The assessment team then “takes a step back” and reviews all of the observations again that are in front of them Like observations may be further consolidated with the consensus of the assessment team
