Process Concepts
• Process Fidelity
• Process Elements
• Models, Guides, Templates, Checklists

Process Fidelity
• When is a Process Defined?– It is documented– Training is provided– Practiced on a day to day basis
• In other words:Practice = Documentation = Training
![Page 6: 1 OVERVIEW Set Context Process Concepts Conducting an Interview Interview & Initial Analysis Exercise Initial Analysis Interview Preparation for CADB Interview](https://reader036.vdocuments.net/reader036/viewer/2022062309/56649f115503460f94c240ad/html5/thumbnails/6.jpg)

Process Fidelity,Continued
• Concepts– What is written down (documented)
is the same as what is practiced
Example: Practice is “true to” the documentation
– Add a consistent training program and you have a defined process
Practice = Documentation = Training

Process Elements (Building Blocks)
• Work Products– Scientific products– Climate databases
• Activities– Steps taken to create a product– Steps taken to create a database
• Agents– Scientist who creates and
maintains the scientific product– Person who creates and maintains
the climate database

Applying Building Blocks, Continued
• Activity Entry Criteria– When can this activity begin?
Example:• Management approval
• Process Definition Plan completed
• Activity Exit Criteria– when is this activity complete?
Example:• Process guide ready for review
• Scientist satisfied with process guide

Applying Building Blocks, Continued
• Activity Input– What products (data) are used by
this activity?
Example:• GTS data, Satellite data, etc…
• Activity Output– What products are produced by
this activity?
Example:• Daily Climate data

Model, Guides, Templates, Checklists
• Process Representation
Need to:– Standard way to express process
definitions– Present process definitions in a format
that facilitates communication
• Benefit– A well-defined and formally represented
process can be used to:• Communicate steps to be taken to achieve
product development
• Capture software process knowledge for reuse

Models, Guides, Templates, Checklists
Examples
• Graphical Process Model– A detailed description of a process– A graphical representation for
modeling and analyzing elements and their relationship, e.g. data flow, work flow, dependencies, etc.

• Assigning roles
• Creating a meeting agenda
• Ground rules (confidentiality)
• 80/20 rule

• Interviewing Process (key concepts)– “Active Listening”– Ask “Open Ended” questions– Manage time– Validate / Restate what was said
(Clarify information)– Summary “Yes/No Questions”– Thank the interviewee
