" 78.95%" and p-value equal " 0.000" which is less than 0.05, that means (Differentiate between added value activities and non added value activities). 2. In item No. (6) the weight mean equal " 78.42%" and p-value equal " 0.000" which is less than 0.05, that means (managing relations between the organization and both customers and suppliers). 3. In item No. (5) the weight mean equal " 75.26%" and p-value equal " 0.000" which is less than 0.05, that means (Managing relations and linkage between different business units inside the organization). For general the results for all items of the field show that the average mean equal 3.86 and the weight mean equal 77.22% which is greater than " 60%" and the value of t test equal 8.789 which is greater than the critical value which is equal 2.0 and the p- value equal 0.000 which is less than 0.05, that means industrial companies under the study applied the concept of value chain management. That mean the value chain analysis is a way of assessing competitive advantage by determining the strategic advantages and disadvantages of the full range of activities that shape the final offering to the end user.

105 6.3.4 Industrial companies applied the concept of product life cycle at si gnificance level (α=0.05). To test the hypothesis we use a one sample t test and the opinion of the respondent about the concept of product life cycle ranked according to the weight mean as shown in Table No. (25) as follows: 1. In item No. (5) the weight mean equal " 85.79%" and p-value equal " 0.000" which is less than 0.05, that means (Trade-offs and balancing between the standards specified by the customer in terms of the quality and response time and the selling price.). 2. In item No. (3) the weight mean equal " 83.16%" and p-value equal " 0.000" which is less than 0.05, that means (Determine the place and time of achieving each goal for improving revenue and reduce cost for all the stages of the product life cycle.). 3. In item No. (2) the weight mean equal " 78.42%" and p-value equal " 0.000" which is less than 0.05, that means (Determining the costs for each stage in product life cycle.).
