Question?
Bijoy Kumar Roy – Malda West Bengal India
Introduction The design document is the key of a project.
Important to check repeatedly in the process.
To get IFC stamp approval on the drawing typically, reviewed many times
Appoint other reviewers. Unfortunately, we often don’t find our own errors.
Different stakeholders with different viewpoints are used in the review process.

Review Process Review / verification level process should be mentioned in the approved Project
Management Plan.
A review process is : “a process or meeting during which a work product or set of work
products is presented to project stockholder, personnel, managers, users, customers, or
other interested parties for comment or approval.” (IEEE)
Essential to detect / correct errors in these earlier work products because the cost of errors
downstream is very expensive!!

Review Process (2)
Review Choices:
- Formal Design Reviews (FDR)
- Peer reviews (inspections and walkthroughs)
Used especially in design and coding phase
Bijoy Kumar Roy – Malda West Bengal India
A. Direct objectives – Deal with the current project
Detect analysis and design errors as well as subjects where corrections, changes and completions are required
Identify new risks likely to affect the project.
Find deviations from templates, style procedures and conventions.
Approve analysis or design product. Approval allows the team (Together, Everyone, Achieves, More) to continue on to the next improvement phase.
Review complete within the stipulated 05 working days duration
B. Indirect objectives – are more general in nature.To provide an informal meeting place for exchange of professional knowledge about methods, tools and techniques.
To record analysis and design errors that will serve as a basis for future corrective actions. (very important)
Review Objectives
Bijoy Kumar Roy – Malda West Bengal India
B. Indirect objectives – are more general in nature. Many different kinds of reviews that apply to different objectives.
Reviews are not randomly thrown together.
Well-planned and orchestrated.
Objectives, roles, actions, participation, …. Very involved tasks.
Participants are expected to contribute in their area of expertise.
Idea behind reviews is to discover problems NOT to fix them/
Typically fixed after review and ‘offline’ so to speak.
Very common to review design documents.
Thus they are usually well-prepared initially prior to review.
Review Objectives (2)
Bijoy Kumar Roy – Malda West Bengal India
Software Requirement Specification Review(SRSR) Detailed Design Review (DDR) Data Base Design Review (DDR) Test Plan Review (TPR) Software Test Procedure Review (STPR) Version Description Review (VDR) Operator Manual Review (OMR) Support Manual Review (SMR) Test Readiness Review (TRR) Product Release Review (PRR) Installation Plan Review (IPR) Development Plan Review (DPR) Preliminary Design Review (PDR)
Important to note that a design review can take place any time an analysis or design document is produced, regardless whether that document is a requirement specification or an installation document.
Formal Design Reviews Involved

Formal Design ReviewsPersonal experience in:
Operators’ Manual Users’ Manual
Program Maintenance Manual Staff Users Manual
Installation / Conversion Plan Test Plan(s)
Depend on size of project!

Preparations for the Design Review Participants in the review include the
– Review leader, – Review team, and – Development team.
Review Leader: – appoint team members; – establishes schedule, – distribute design documents, and more
Review Team preparation: – review document; list comments PRIOR to review session. – For large design docs, leader may assign parts to individuals; – Complete a checklist
Development Team preparations: – Prepare a short presentation of the document. – Focus on main issues rather than describing the process. – This assumes review team has read document and is familiar with project’s outlines.

Drawing Initiation & PreparationDrawing Initiation and Preparation
Designer (Drawing Originator)
Draughter (person producing the drawing and well known of the CAD
Standards and Manuals)
If appropriate produce a approved Project CAD Plan Table
Use Drawing Issue Register or similar
Follow designer’s instructions and refer standards , regulations or
similar legislation as require.
Self check against a Drawing Checklist or similar and discuss with
Designer during preparation before handover to others.

Participation in the ReviewDrawing / Report Checking (Use Drawing/Report Checklist) levels based on Drawing / Report
complexity
– Carry out and record checking with Management/Verification Plan
– Verified relevant calculations, standards, risks & equivalent legislation information
– Review Committee Decided Final Approver
Checking Level 1 – Design
– If satisfied add initials Checker and Approved by Approver (Designer)
Checking Level 2 – Drawing Review
If satisfied add initials of Checker and Checked,
Arrange for any amendments to the Drawing by Designer
If satisfied the amendment add initials by Checker
Pass it to the approver
Bijoy Kumar Roy – Malda West Bengal India
Participants in the Review (2) Checking Level 3- Detailed Check
If satisfied add initials Checked,
Arrange for any amendments to the Drawing by Designer
If satisfied the amendment add initials by Checker
Pass it to the approver
Checking Level 4 - External Check
If satisfied add initials Checked,
Arrange for any amendments to the Drawing by Designer
If satisfied the amendment add initials by Checker
Pass it to the approver for internal organization
When complete send to the external Checker. Consider discuss and resolve queries. If
revision is necessary.

Participants in the Review (3)
Checking Level 5 – As defined in the Management Plan
Carry out the required verification process if define extra checking
Approval
- Final review is complete when satisfied of each drawing.
Note: Record and check prints and/or CAD record versions in project records.
Remove obsolete drawings from use and clearly mark "SUPERSEDED", or
otherwise
Bijoy Kumar Roy – Malda West Bengal India
Participants in the Review (4) Review Leader – Design Engineering Consultant
Needs to be external to the project team.
Must have knowledge and experience in development of the
review type
Seniority at least as high as the project leader.
Good relationship with project leader and team
Generally, this person really needs to know the project’s material
and should NOT be the project leader –Would impact objectivity!
Would miss things entirely!
Bijoy Kumar Roy – Malda West Bengal India
Participants in the Review (5)Review Team
Needs to be from senior members of the team with other senior
members from other departments (Architectural, Civil,
Electrical, Mechanical, IT Security etc.).
Why?
Escalation?
Team size should be 3-5 members.
Too large, and we have too much coordination.
This is a time for serious business – not lollygagging!
Bijoy Kumar Roy – Malda West Bengal India
The Design Review Session Review Leader is key person for sure!
Start with short presentation (development team)
Comments by members (review team)
Comments discussed to determine required actions team must perform(review and development teams)
Decisions regarding design product – tells project’s progress. Full approval Code “A” - Continue on to next phase (may have minor corrections)
Partial approval Code “B”- Revised and Resubmit)
• Continue to next phase for some parts of project; major action items needed for remainder of project.
• Continuation of these parts granted only after satisfactory completion of action items
– Granted by review team member assigned to review completed actions or by the full review team or special
review team or by some other forum
Rejection of Approval Code “C” – demands a repeat of Design Review
• Project has major defects, critical defects
Rejection Code “D”
Bijoy Kumar Roy – Malda West Bengal India
The Design Review Report Review Leader’s primary responsibility following the review.
Important to perform corrections early and minimize delays to
project schedule.
Report contains:
Summary of review discussions
Decision about project continuation
Full list of action items – corrections, changes, additions the project team
must perform. For each item, anticipated completion date and responsible
person is listed.
Name of review team member assigned for follow up.
Bijoy Kumar Roy – Malda West Bengal India
Follow up Process
The ‘follow-up person’ may be the review team leader him/herself
Required to verify each action item fixed as condition for allowing project to continue to next phase.
Follow up must be fully documented to enable clarification of the corrections in the future, if any.
Bijoy Kumar Roy – Malda West Bengal India
Oftentimes ProblemsSometimes entire parts of DR are often worthless due to – Inadequately prepared review team, or – Intentional evasion of a thorough review.
Tipoff:– Very short report – limited to documented approval of the
design and listing few, if any, defects
– Short report approving continuation to next project phase in full - listing several minor defects but no action items.
– A report listing several action items of varied severity but no indication of follow-up (no correction schedule, no documented activities, …)

1. Design Review Infrastructure Develop checklists for common types of design documents.
Train senior professionals to serve as a reservoir for Design Review Teams (Together, Everyone, Achieves, More).
Periodically analyze past Design Review effectiveness.
Schedule the Design Reviews as part of the project plan.
Guidelines for Design review
2. The Design Review TeamReview teams size should be limited, with 3–5 members being the optimum.
Bijoy Kumar Roy – Malda West Bengal India
3. The Design Review Session
Discuss professional issues in a constructive way refraining from personalizing
the issues. Keep to the review agenda. Focus on detection of defects by verifying and validating the participants'
comments. Refrain from discussing possible solutions.
If disagreement about an error - end the debate by noting the issue and shifting
its discussion to another forum. Properly document discussed comments, and the results of their verification
and validation. Review session should not exceed two hours.
Guidelines for Design review (2)
Bijoy Kumar Roy – Malda West Bengal India
4. Post-Review ActivitiesSome example Prepare the review report, including the action items Establish follow-up to ensure the satisfactory performance of all
the list of action items Test font size and font are different in the same drawing Drawing dimensions are not very clear Etc.
