QFD – House Of Quality:

Analysis:

Material and process both are standard.

Voice of customer is to reduce the cost.

For cost reduction there is a need of

redesigning the business strategy.

TOWS Matrix:

 

Strength: Weakness:

* Quality Product* Lack of promotional activities

* British and Denmark Standard Certification

* Focus on domestic Markets

* ISO Certified* Exports are considered optional

* Leading Pipe manufacturer  

   

Opportunities:

Due to boom in construction the demand of pipe is increased so DADEX must focus on suitable

strategy to grab the opportunity.

Focus on exports and promotional activities to grab

the opportunity.

* Boom in construction

 

Threats:

Maintain the strength by producing qualitative products.

1) Reduce the cost by doing backward integration.

2) Focus on promotional activities.

3) Focus on exports.

* Inflation

* Exchange Rate

* Profit margins are squeezing

* Other competitors

1. Backward Integration (Raw Material)

2. Focus on promotional activities.

3. Focus on exports.
