Business failure is an important issue for companies in the Gaza Strip uncertain environment. This paper aimed to explore the critical factors that have the potential to cause contractor's business failure and to determine their level of severity from contractor's viewpoint. This paper has considered. Critical factors were listed under five groups: financial and political, contractual, managerial, organizational, and economical causes. Contractors have been advised to consider the most critical factors that have the potential to cause business failure. The most critical factors include: cost of materials, lack of resources, delay in collecting dibs from clients, monopoly, changing funding sources, dealing with suppliers and traders and Israeli attacks.

While economic activity and growth stimulators in conventional economies are largely related to internal economic variables and policies, the Palestinian economy operates in an environment rife with different internal and external risks and challenges, which significantly affect and change the economic situation. The most external challenges facing the Palestinian econ- omy include the Israeli occupation and closure (Econom- ic Forecast Report, 2018). Organizations need to be well prepared, organized, and plan appropriate strategies to stay relevant, competent, and active, in the industry ( Abu Bakar et al., 2016). In Gaza Strip, construction has a positively affecting on economic, social, educational and vocational sectors and other sectors. It has a large contribution to the gross do- mestic product directly, in addition to the indirect contri- bution through the related activities such as manufactur- ing, electricity, water and other economic activities. It used to employ an average of 14.4 % of Palestinian labor force volume (PCU, 2017). Present contribution to real GDP by construction at the end of year 2018 was 6% and 6.7% in Gaza Strip and the West Bank respectively. The rate of change of real value added by construction be- tween year 2017 and 2018 recorded a significant contrac- tion by (-22.5%) in the Gaza Strip. During the same pe- riod, a significant expansion was noticed by (+6.0%) in the West Bank (UNSCO Socio-Economic Report, 2019). Among other unique characteristics of life in Palestine, the construction industry stands out from other parts of the economy. Construction is heavily affected by eco- nomic cycles and political environment, which change frequently and dramatically in Palestine in general and in Gaza Strip in particular. The construction industry has a significantly high rate of business failure due to high op- erating risks and uncertain conditions. All over the world, contractors compete fiercely in the marketplace, exposing themselves to risk of failure, as well as the prospect for success. Palestine is not an exception. In the last two years, more than 50 contracting companies exposed to failure as a result of unnatural environment in Gaza Strip. Currently, there are about 70 contractors fac- ing business failure due to their inability to cope with environmental, subjective and competitive conditions. This research will identify the most important and critical factors that lead to the failure of contractors in order to enhance the ability of these companies to survive, com- pete, and overcome the abnormal conditions. 2- Literature Review 2.1 Definition of Failure There are many definitions of business failure. Altman (1968) defined the failure from an economic viewpoint and said that a company is considered to have failed if the realized rate of return on invested capital, with allowanc- es for risk considerations, is significantly and continually lower than prevailing rates on similar investments. Ber- ryman (1893) recognized it as the condition of the firm when it is unable to meet its financial obligations to its creditors in full. It is deemed to be legally bankrupt and is usually forced into insolvency liquidation. Another defi- nition of failure denoted by Watson & Everett (1883) as attributed business failure to four different situations: discontinuance for any reason; ceasing to trade and credi- tor loss; sale to prevent further losses; and failure to make a go of it. Shepherd (2003) show that, the failure occurs when a fall in revenues and/or a rise in expenses are of such a magnitude that the firm becomes insolvent and is unable to attract new debt or equity funding; consequent- ly, it cannot continue to operate under the current owner- ship and management. Ucbasaran et al. (2010) said that the failure as not only the sale or closure of a business due to bankruptcy, liquidation, or receivership but also the sale or closure of a business because it has failed to meet the entrepreneur‟s expectations, which reflects the varying personal thresholds of performance among entre- KHALID AL HALLAQ/ CRITICAL FACTORS CAUSING CONTRACTOR'S BUSINESS FAILURE IN GAZA STRIP 11 preneurs.. David O. Mbat & Eyo (2013) said that the failure could be seen in terms of the inability of a corpo- rate organization to conform itself with its strategic path of growth and development to attain its economic and financial objectives as well as legal obligations. 2.2 Causes of Failure A number of researchers had studied the causes of con- tracting business failure. Dun and Bradstreet Corporation (1986) had identified the major causes of business fail- ures in the construction industry as; economic factors, inexperience, poor sales, expense, customer, fraud and neglect, asset and capital, and disaster. They found the most significant failure cause as economic factors. Within the economic factors category, there were five subcatego- ries that were bad profit, high interest rates, loss of mar- ket, no customer spending and no future. Schleifer (1989) also identified ten causes as the bane of the construction industry. The first five of the identified factors are related to business strategies and the second five are related to accounting considerations. The factors were; increasing project size, expanding into unfamiliar locations, replac- ing key personnel, moving into new construction, not maturing in management as business expands, using poor accounting systems, evaluating project profit incorrectly or not in time, not controlling equipment costs, not billing or collecting effectively and jumping between computer- ized accounting systems. The findings indicated that over 80% of the failures were caused by five factors, namely insufficient profits (27%), industry weakness (23%), heavy operating expenses (18%), insufficient capital (8%) and burdensome institu- tional debt (6%). All these factors, except for industry weakness, are budgetary issues and should therefore be handled by companies that are cognizant of the effects of these factors on their survivability ( Donkor, 2011). Argenti (1976) in his book 'corporate collapse' summa- rized what was written in failure. He concluded six main causes as a result of what written about the subject of company failure follows; top management, accounting information, change, accounting manipulation, rapid ex- pansion, economic cycle. Hartigan (1973) listed seven main causes of failure were as follows: Lack of capital, Under costing, lack of con- trol, lack of advice, the government, trade fluctuations and fraud. Jannadi (1997) had previously presented a study of the factors that contribute to the failure of construction con- tractors in Saudi Arabia and found that the most im- portant factors were: difficulty in acquiring work, bad judgment, lack of experience in the firm‟s line of work, difficulty with cash flow, lack of managerial experience, and low profit margins. Davidson and Maguire (2003), based on their accountan- cy experience, identified ten most common causes for contractor failures as: growing too fast, obtaining work in a new geographic region, dramatic increase in single job size, obtaining new types of work, high employee turno- ver, inadequate capitalization, poor estimating and job costing, poor accounting system, poor cash flow, and buying useless stuff. Enshassi, et al. (2006) identified the main factors that cause business failure based on contractors‟ view point in Palestine. The research identified delay in collecting debt from clients (donors), border closure, heavy dependence on bank loans and payment of high interest on these loans, lack of capital, absence of industry regulations, low profit margin due to high competition, awarding con- tracts by client to the lowest bidder, and lack of experi- ence in contract management. Kivrak and Arslan (2008) examined the critical factors causing the failure of construction companies through a survey conducted among 40 small to medium-sized Turk- ish construction companies. A lack of business experience and the country‟s economic conditions were found to be the most influential factors in company failure. Mahamid (2011) ranked the factors as highly influential with huge potential to cause contractor‟s business failure based on contractors‟ view point in Palestine: fluctuation in construction material costs; delay in collecting dibs from clients; lack of experience in contracts; low margin of profit due to competition; and closure and limitation of movement between West Bank areas. Mbat and Eyo (2013) concludes that there are a lot of factors, internal and external, to the firm could be respon- sible for corporate failure. The corporate should consider the relative influence of management, board of directors, employees, external auditors, regulatory bodies, and gov- ernment to avert failure. Holt (2013) aimed to synthesize published knowledge in construction business failure to explore the failure agents. He concluded that the broad practical propositions to help negate the potential nega- tive effects are the managerial, financial, company char- acteristics, and macroeconomic environment. Wang and Wu (2017) adopted modified two-stage learn- ing algorithm to predict business failure. The modified learning model can utilize geometric feature of the data to discover the low-dimensional manifold embedding in the high-dimensional space by coordinate representations. It is more suitable to select feature values for financial data. The first stage, the stepwise forward selection approach is easy to understand and implement, and can enhance the performance of the selective ensemble model efficiency. In the second stage, different selective ensemble models are integrated according to normal or failed firms, which can exert the respective advantage of ensemble models to process the suitable firms. Doumpos et al. (2017) exam- ined the development of corporate failure prediction models for European firms in the energy sector, using a KHALID AL HALLAQ/ CRITICAL FACTORS CAUSING CONTRACTOR'S BUSINESS FAILURE IN GAZA STRIP 12 large dataset from 18 countries. The construction of mod- els is based on multiple criteria decision aid approach taking into consideration both ordinal criteria and nomi- nal country-sector effects. The results confirmed the im- portance of incorporating energy-related data to the anal- ysis of the distress risk for firms in the energy sector. It was found that data related to the quality and reliability of energy networks, energy sustainability factors, as well as the size and openness of a country's internal energy mar- ket, can provide valuable additional information com- pared to firm-specific attributes and economic/business environment. Venugopal (2018) explained the persistence discourse of failure in development as a point of departure to under- stand what is signifies, how it is structured, and what consequences it bears. He framed failure as a socially constructed category. He also concluded that changing sets of beneficiaries, definitions, goals, and indicators of success, and outcomes that are multi-layered, evolve over time, hard to measure, and generate unpredictable exter- nalities, every successful project can also be reinterpreted as a failure. Cui et al. (2018) concluded that: the compa- ny's business capacity cannot adapt to the company's de- velopment is the most primary factor in the green busi- ness failure. While the "short-term investor mind-set and less investment" had the strongest effect on green busi- ness failure. 3- Methodology A total of 73 factors that might affect contractors‟ busi- ness failure were defined through a detailed literature review of relevant research studies (Hartigan, 1973; Ross & Rami, 1973; Cohen, 1973; Argenti, 1976; Dun and Bradsteet, 1986; Kangari, 1988; Schleifer, 1989; Abidali and Harris, 1995; Osama, 1997; Assaf, S., 2004; Peter- son, 2005; Enshassi et al., 2006; Strischek and Mclntyre, 2008; Donkor, S., 2011). The factors were tabulated in a questionnaire form and the questionnaire was reviewed by three groups of experts to test its content validity. The target population in this study is all contractors of the first, second and third categories for building works that have valid registration by the Palestinian Contractors Union with a total of 203 contractors. The following statis- tical equation was used to determine the sample size: )1( 2   ZX ))1(( 2 XEN NX n   Where: Z: (1.96 for 95% C.I) P: (0.50) n: Sample size N: Popu- lation size =186 E: Maximum Error of estimation (0.07) 133 ))9604.0)05.0)(1202(( 9604.0203 ))1(( 9604.0)5.01(5.096.1 2 2 2        XEN NX n X Therefore, the calculated sample size is 133 contractors based on a 95% confidence level. The questionnaire was sent out to a total of 133 contractors asking their contri- bution in ranking the identified 73 factors in terms of severity using an ordinal scale. The ordinal scale that was used are 1 = very low influence, 2 = low influence, 3 = moderate influence, 4 = high influence, and 5 = very high influence. Only a total of 101 completed questionnaires were returned representing a good response rate of 75.93%. Factor analysis was employed to reduce a large number of variables (factors of business failure) to a smaller set of underlying factors that summarize the essential infor- mation contained in these variables. Using SPSS v.22, Principle Component Analysis with Varimax rotation were performed to set up which items could capture the aspects of same dimension of the proposed determinants causes of business failure and examine the underlying structure or structure of interrelationships among these causes. In order to perform the factor analysis for pro- posed items, all appropriate checks, requirements and procedures were fulfilled, as mentioned in Table (1). Three main three phases were proceeded to accomplish factor analysis, as follows: preliminary analysis, factors extraction, and factors naming and interpretation. Table (1): Factor analysis process requirements and criteria Factor analysis phase Requirement Acceptation cri- teria References Preliminary analysis (First phase) Type of the study data (variables) Subjective varia- bles (Yong and Pearce, 2013) Distribution of the data Normal distribu- tion (Sample size of the study larger than 30) (Hair et al., 2010) (Field, 2009) Sample size More than 50 (Winter et al., 2009) (Sapnas and Zeller, 2002) Data reliability test (Internal consisten- cy) Cronbach coeffi- cient alpha > 0.7 (Pallant, 2005) Factorability of the correlation matrix (Visual inspection of the correlation matrix) Each item (variable) correlated with several other varia- bles with correlation coefficients greater than 0.30 and none of the correlation coefficients has a (Field, 2009) (Tabachnick and Fidell, 2007) KHALID AL HALLAQ/ CRITICAL FACTORS CAUSING CONTRACTOR'S BUSINESS FAILURE IN GAZA STRIP 13 Factor analysis phase Requirement Acceptation cri- teria References value greater than 0.9.

(Mane and Nagesha, 2014) (Hair et al., 2010) Factors ex- traction (Second phase) Communality val- ues Each item com- munality value more than 0.5 (Field, 2009) Cumulative per- centage of variance explained by the extracted factor solution The cumulative variance ex- plained by the extracted factors should be greater than 50% of total variance ex- plained. (Meyers et al., 2006) (Mane and Nagesha, 2014) Loaded items and extracted factors properties Each item should has at least one factor loading value equal or more than (0.5). (Pallant, 2005) (Mane and Nagesha, 2014) Each one of the extracted factors should include at least three items to be acceptable. (Costello and Os- borne, 2005) Any item loaded on more than one factors with factor loading greater than 0.5 should be removed “no cross-loading items”. (Henson and Rob- erts, 2006) (Hair et al., 2010) Reliability measure of the extracted factors The variables formed each fac- tor explains the measure within this factor based on Cronbach‟s Alpha (Cα) value, which should be more than 0.7 (Pallant, 2005) Factors nam- ing and in- terpretation (Second phase) Arrangement of extracted factors Extracted factors should be ar- ranged and num- bered in a de- scending order on the basis of the amount of vari- ance explained by each one.

KHALID AL HALLAQ/ CRITICAL FACTORS CAUSING CONTRACTOR'S BUSINESS FAILURE IN GAZA STRIP 14 4- Result and Discussion Factor analysis was used to examine the pattern of inter- correlations between the 73 items/ variables of success factors for the application of EMS in an attempt to reduce the number of them. It also used to group items/ variables with similar characteristics together. In other words, it identified subsets of items/ variables that correlate highly with each other, which called factors or components. Fac- tor analysis was conducted for this study using the Prin- cipal Component Analysis (PCA). Appropriateness of factor analysis The data was first assessed for its suitability to the factor analysis application. There were many stages of that as- sessment: 1. Distribution of the data: With the base of Central Limit Theorem, the data collected can be considered normally distributed because sample size for this study was 101 and it was larger than 30 as proposed by Hair et al. (2010). Therefore, the normal distribu- tion requirement for factor analysis application for this part of study has been satisfied as stipulated by Field (2009). 2. Validity of sample size: the reliability of factor analysis is dependent on sample size. Factor analy- sis/ PCA can be conducted on a sample that has few- er than 100 respondents, but more than 50 respond- ents. The sample size for this study was 101. 3. Data reliability test: The first stage of the quantita- tive analysis was related to the reliability test where the reliability of the questionnaire was tested accord- ing to the Cronbach‟s alpha measurement. Through the analysis that has been done, the alpha reliability of the scale of 73 items (factors) in this study was 0.94 for the items indicating that 94% of the variance of the total scores of all factors can be attributed to systematic variance. Since the result was achieved above 0.7, it showed that all items have indicated in- ternal consistency and achieved high reliability as proposed by Pallant (2005). 4. Kaiser-Meyer-Olkin (KMO) and Bartlett's test: the Kaiser-Meyer-Olkin (KMO) sampling adequacy test and Bartlett's test of Sphericity were carried out. The results of these tests are reported in Table (1). The value of the KMO measure of sampling adequa- cy was 0.792 (close to 1) and was considered ac- ceptable and marvelous because it exceeds the mini- mum requirement of 0.50 and it is above 0.90 („su- perb„ according to Kaiser, 1974; Field, 2009; Zaiontz, 2014). Moreover, the Bartlett test of sphe- ricity was another indication of the strength of the re- lationship among items/ variables. The Bartlett test of sphericity was 1417.778, and the associated sig- nificance level was 0.000. The probability value (Sig.) associated with the Bartlett test is less than 0.05, which satisfies the PCA requirement. This re- sult indicated that the correlation matrix was not an identity matrix and all of the items/ variables are cor- related (Field, 2009; Zaiontz, 2014). Table (1): KMO and Bartlett's test for business failure factors KMO and Bartlett's test Kaiser-Meyer-Olkin Measure of Sampling Adequacy. 0.792 Bartlett's Test of Sphericity Approx. Chi- Square 1417.778 DF 378 P-value 0.000 Cronbach's Alpha (Cα) 0.90 After all the appropriate checks were performed and indi- cated that all the 73 variables should be retained in an initial capture of factors, using the principal component analysis approach with exploratory factor analysis through SPSS v.22. Several criteria should be achieved in order to accept the extracted solution obtained in any phase and to consider this solution as a suitable final so- lution for the involved variables. The following sections explains these criteria and process of investigation for the final solution (after sixteenth run). 1. Communalities (common variance) Communality is the first criteria to be checked in the ex- tracted solution. It reveals the percentage of variance in a particular variable that is explained by the factor (Wil- liams et al. 2010). Larose (2006) has also claimed that communalities less than 0.5 were considered too low, since this would meant that the variable shares less than half of its variability with other variables. Higher com- munality value means higher importance of the variable. After (sixteenth run) of factor analysis, we get (28) fac- tors that communality values confirms with this assump- tion as their values larger than 0.5.

Total Variance Explained By using the output from iteration 1, there were five ei- genvalues greater than 1 (Figure 1). The eigenvalue crite- rion stated that each component explained at least one item's/ variable's worth of the variability, and therefore only components with eigenvalues greater than one should be retained (Larose, 2006; Field, 2009). The latent root criterion for some factors to be derived would indi- cate that there were five components (factors) to be ex- tracted for these items/ variables. Results were tabulated in Table (3). The five components solution explained a sum of the variance with component 1 contributing 28.894%, component 2 contributing 11.105%, component 3 contributing 8.597%, component 4 contributing 7.010%, and component 5 contributing 5.306%. All the remaining factors are not significant. The five components were then rotated via varimax (or- thogonal) rotation approach. This approach does not change the underlying solution or the relationships among the items/ variables. Rather, it presents the pattern of loadings in a manner that is easier to interpret factors (components) (Reinard, 2006; Field, 2009; Zaiontz, 2014). The rotated solution revealed that the five compo- nents solution explained a sum of the variance with com- ponent 1 contributing 14.405%, component 2 contrib- uting 14.047%, component 3 contributing 11.436%, component 4 contributing 11.325%, and component 5 contributing 9.522%. These five components (factors) explained 60.734% of total variance for the varimax rota- tion.

Scree Plot The scree plot below in Figure (1) is a graph of the ei- genvalues against all the factors. This graph can also be used to decide on some factors that can be derived. The point of interest is where the curve starts to flatten. It can be seen that the curve begins to flatten between factors 1 and 5. Note also that factor 6 has an eigenvalue of less than 1, so only five factors have been retained to be ex- tracted.

Rotated Component (Factor) Matrix Table (4) shows the factor loadings after rotation of 28 items/ variables on the five factors extracted and rotated. The pattern of factor loadings should be examined to identify items/ variables that have complex structures (Complex structure occurs when one item/ variable has high loadings or correlations (0.50 or greater) onto more than one factor/ component). If an item/ a variable has a complex structure, it should be removed from the analy- sis (Reinard, 2006; Field, 2009; Zaiontz, 2014). It was loading onto five components. On the basis of such restriction, seven items loaded on the first factor, six items loaded on the second factor, five items loaded on the third factor, five items loaded on the fourth factor, five items loaded on the fifth factor “Table (5)”. It is worth noting here, that rotated component ma- trix table should be checked only after satisfying all re- quirements mentioned above such as MSA values, com- munalities, KMO, p-value for Bartlett‟s test of sphericity and etc.,. However, three conditions should be satisfied in this table to consider the solution acceptable.

Rotation Method: Varimax with Kaiser Normalization. Once factors have been extracted and rotated, it was nec- essary to cross checking if the items/ variables in each factor formed collectively explain the same measure within target dimensions (Doloi, 2009). If items/ varia- bles indeed form the identified factor (component), it is understood that they should reasonably correlate with one Khalid Al Hallaq/ Critical Factors Causing Contractor's Business Failure in Gaza Strip 17 another, but not the perfect correlation though. Cronbach's alpha (Cα) test was conducted for each com- ponent (factor). The higher value of Cα denotes the greater internal con- sistency and vice versa. An alpha of 0.60 or higher is the minimum acceptable level. Preferably, alpha will be 0.70 or higher (Field, 2009; Weiers, 2011; Garson, 2013). Ac- cording to the results which were tabulated in Table (4), Cα for each factor higher than 0.7, they are considered to be excellent. Financial and political factors It is clear that the seven items that loaded on this group are related to financial and political factors that can cause business failure according to the view point of local contractors. This group accounts for 14.41% of the total variance explained and the reliability score (Cronbach‟s α) of 0.87. According to factor analysis theo- ry, the first factor accounts for the largest part of total variance of the data. Hence, it implies that high cost of materials considered as the most important factors cause business failure in Gaza Strip. It is closely followed by lack of resources, delay in collecting dibs from clients, monopoly, changing funding sources and dealing with suppliers and traders. Most of these factors are financial factors but associate with political conditions. According to the statistical analysis, there is no weighted difference between the financial and political factors ex- cept the lowest ranking factor, which was Israeli attacks. It may be interpreted as most of companies in Gaza strip are not exposed to Israeli attacks directly, and if exposed to attacks, they compensate by local authorities. Contractual factors It can been seen from Table (6) that there are six items\variables that loaded on this group. The total variance was 14.04% and the reliability score (Cronbach‟s α) of 0.82. Table (6) illustrates that the own- er absence from the company, low margin of profit due to competition, owner involvement in construction phase, estimating practices are the top ranked four factors. These are closely followed by award contracts to lowest price and monopoly of some important material for construc- tion. The owner absence from the company is the most factor affecting to the failure of company because the loss of experience in the stuff and not good following the work result the failure, the second factor more competitive lead to less profit in the contract from the contractor side, the monopoly is important factor in failure in Gaza because the closure of ports. Managerial factors There are five factors listed under this group as shown in Table (6). The highest three business failure causes are the use of project management techniques, bad decisions in regulating company policy, and company organization. It is closely followed by two factors which were labor productivity and improvement and procurement practices. It is quite interesting to note that the use of the project management techniques is heavily affecting in failure because the very good techniques lead to good manage- ment at the project less the failure, the bad decision at company affect more on the work and make problem at the sites that is a failure, company organization to the employee in the company is good less failure and choice bad engineer or any employee do the failure, good productivity for the employee is important factor to less the failure, less factor affecting on the failure in this group procurement practices. Organization factors Table (6) illustrates the ranking of five factors under this group. The top-ranked factors are increase number of projects, increase size of projects and increase number of employees. That more affecting three factor because more skilled employees are needed to sequence the project without problem, increase successful project less failure. According to the contractors, there is significance differ- ence between the three top factors and the two lowest factors which were contractor's difficulties in achieving bank facilities and problem rising due to temporary items in the contract, this factor lead to failure because no bank facilities is stopping the project that may lead to financial failure, the lowest factor in the items of the contract lead to more problem between the owner stuff and contractor stuff may lead to failure. Economic factors It is obvious that the five factors that loaded on this group are related to economic factors that can cause business failure according to the viewpoint of local contractors. The first factor accounts for the largest part of total variance of the data. Hence, it implies that banks poli- cy considered as the most important in the economic factors in Gaza Strip and it is heavily affecting factor. The other factors respectively are change work from private to public or vice versa, general government restriction, in- flation, bill and collecting effectively. The change of the type of work that need to skilled employee and more ex- perience project manager to do best in the project new type without failure, inflation is a worldly reason from financial viewpoint and contractor. Conclusion Business failure has become an increasingly important issue in the Gaza Strip construction industry due to ongo- ing closure that cause business instability. The failure of a company may cause considerable losses to all parties in the construction industry. In particular, it may affect vari- ous stakeholders, such as clients, contractors, subcontrac- tor, suppliers, consultants, investors, or employees. There are many factors that could be responsible for the contractors failure which impact negatively the local eco- nomic environment. The main objective of this paper is to identify the critical factors that have the potential to cause contractor's business failure in the Gaza Strip and to de- termine their level of severity from contractor's view- point. Seventy-three factors were considered in this re- search paper, and then reduced to twenty-eight factors using factor analysis. They were listed under the follow- ing five groups: (1) financial and political, (2) contractu- Khalid Al Hallaq/ Critical Factors Causing Contractor's Business Failure in Gaza Strip 18 al, (3) managerial, (4) organization, and (5) economical. The most critical factors that highly affect contractor's business failure are: (1) high cost of materials, (2) Lack of resources, (3) Delay in collecting dibs from clients, (4) Monopoly, (5) Changing funding sources, (6) Dealing with suppliers and traders, (7) Israeli attacks. It is recommended that contracting companies should consider the influence of the previous factors to avert failure. They should also focus on the remedies of failure by using a blend of managerial and organizational actions to overcome the impacts of financial and political impli- cations of failure.
