•Project Title: Modification of QA Procedure for issue of Inspection note for FRP Shelter
•Background & Reasons for selecting the
Project: SQAE(E) Mumbai is responsible to carry out Quality Assurance of FRP Shelters at various stages as mentioned
below : a) Vetting of S/O b) Study of Drawings & Specification c) Testing of raw material d) Association in pilot sample QA check with user e) Bulk supply QA check f) Issue of I-Note
D M A I C
These Operational Task orders are generally placed by HQ 15 Corps and HQ 14 Corps, C/o 56 APO under their power for operational work by Engineer Regiments. Since the requirements are of operational nature, hence S/Os are placed with a very short delivery schedule. (as per data available for the S/Os placed during 2006, 2007 & 2008 so far).
As per DGQA standing order all QA Call letters of manufacturer needs to be cleared within 28 days where testing is involved. Due to short delivery schedule, the time duration has been cut down by eliminating various steps of QA checks and application of concurrent engineering to achieve Quality products.
D M A I C
D M A I C
Currently the average total time for issue of I-note on completion of QA of FRP shelters from date of offer / receipt of QA call letter by SQAE (E) Mumbai is 34 days which has been obtained from data held.
The order placing authority i.e. HQ 15 Corps / HQ 14 Corps and Engineer Regiments used to express their urgency due to their programme and climatic condition prevailing and insisted to shorten the QA check and clear the lot at the earliest, so the stores can reach them before the road gets blocked at high altitudes due to winter snow fall. Moreover, they further require some time for erection of these shelters before winter sets in.
D M A I C
The procedure of manufacturing of FRP shelters are is as follows :
•Preparation of moulds as per drawing.
The 4-6 men shelter requires 69 moulds and 8-10 men shelters requires 75 moulds.
•Mobilisation of Raw material like Resin, Gel Coat, Chop strand Mat (CSM), Woven Roving (WR), etc. •Procurement of accessories like - a) Flower picket duly heat treated at show end b) Hardware / Fasteners duly galvanized c) Repair kit d) Electrical installations
D M A I C
e) Bath room / Toilet Chamber accessories and fittings
f) Various tools
Hand Laying of Male/Female moulds of panels as per S/o requirements.
• Curing time on mould.• PUF filling on panels.• Resin filling by RTM process.• QA check by manufacturer of panel.• Repair of delaminated and split panels. • Erection of shelter.• Marking of panels.
D M A I CQA OF BULK SUPPLY : The procedure of QA check for Bulk supply,
carried out before issue of I-note, as under : Quantity Check : Total qty of panels as per shelter as offered are required to be checked. Visual Inspection : Completeness , workmanship, proper fitment after sealing are checked. Dimensional Check : Dimensional check as per drawing. Checking of panels in erected condition for de-lamination, and splits. Weighment check Repair of panels where there are rejection due to de- lamination and splits. Recheck of repaired panels.Checking of spares , accessories & tools. Release and despatch of shelters and Quality Assurance records.
D M A I C
If the checks are found to conform as per governing drawings and specification, the panels are required to be stamped by concerned QA staff. Thereafter , preparation of QA report and finally issue of acceptance Inspection Note.

Potential savings from the project :
Characteristics : Total clearance time (TCT)
Measures : Time in days for TCT ( LC = 1 day ) Defect Definition : Any clearance letter / issue of I-note
taking more than 10 days is considered as a defect.

BRAIN STORMING
A detailed brain storming was done with the following present
Firm Management Rep and Manager QC
SQAO
QAO
QA Staff ( 12 Nos )
D M A I CBRAIN STORMING
The following points immerged from this :
•Tasking of QA team to be done keeping In mind any other task assigned to them•QA call letter if received in office after Mon meeting , gets delayed.•Forward of samples to lab gets delayed for two days , if QA undertaken on Friday•Stamping of bulk ( requires 4-6 hrs ) was done after / during 2nd tier QA•Delay in undertaking of QA due to heavy commitment of QA team•Shortage of QA staff.•Insufficient of manpower available with the firm for drawl of samples.•Clearance time of bulk remains same , irrespective of lot size.•Delay in receipt of lab results•Delay from rework and repair
D M A I CTAKE AWAY FROM BRAIN STORMINGProcess needs to be changed to as follows:The firm should preferably offer bulk supply by Fri ( A/N) / Mon ( F/N) for detailment of QA team during Monday meeting.In case of heavy commitment , QA of bulk offered by the firm be undertaken on Sat/Sun.Second tier QA of bulk be carried out along with QA of first tier.Stamping to be done prior to drawl of samples but after verification of offered quantity.Firm should arrange sufficient man power depending on Lot size for drawl of samples.Stamping done prior to drawl of samples is for identification purpose only and if test results found conforming to specification same to be treated as acceptance mark.QA team from different sections of the office be detailed in case of heavy commitments.
D M A I CTAKE AWAY FROM BRAIN STORMINGWith receipt of letter of intent by the firm, firm be asked to offer raw material at their risk and cost, so that by the time the S/O is recd firm can be almost be ready to offer the bulk for insp.Increase in no. of moulds into serviceIncrease of expertise in mould laying through trgApplication of high quality releasing agentMonitoring of laying and curing time
D M A I CSUMMARY OF ANALYSIS PHASEThrough brain storming session , VA/NVA activities have to be identified.Identification of measure causes for increased total clearance time has been identified ( time for QA check and testing of samples ) Through process analysis , approach to solving of problem needs to be identified.From brain storming exercise , summary of various improvements have to be obtained.With receipt of letter of intent by the firm, firm be asked to offer raw material at their risk and cost, so that by the time the S/O is recd firm can be almost be ready to offer the bulk for insp.Increase in no. of moulds into serviceIncrease of expertise in mould laying through trgApplication of high quality releasing agentMonitoring of laying and curing time

• Process Inspection of Bulk Store• Product of the process I-Note• Metric No. of days taken for issue of
I-Note• Standard Max 10 days• No. of I-Note issued 25• No. of I-Note issued within 10 days 14• No. of potential action leading 10
to/create defect• The Yield for process 14/25 =0.56• Defect Rate 1-0.56 = 0.44
• Defect per opportunity 0.44/10 = 0.044• Defect per million opportunity 0.044 x (10 power 6 )= 4400• Sigma level = 3.25 To 3.20
