B5 CARS EIS Eis is basically used by senior management to take take decisions.It requires an environment to operate .The reason why it is expensive to operate because it requires a lot money and updatation.It is used by senior manager and it requires maintainence and related technician to run it. In requires a lot of info which would be difficult to source.Moreover it would be open to hacking so it would require a security normally an antivirus.It is used in basically large organizations. Moreover there would be some sort of restrictions on the info available because the competitor would felt uneasy to give. It requires a lot of info or you can say data to be stored which wont be possible without a proper heavy computer system and that computer would require maintainence too. Part(b) The reason why internally source info use merely would not be good for the organization as that it would result in lack of progress for us and progress wont be possible without external source of info. Competitors could use our info and beat us in product features and sales but we wont be able to do so because we would be lacking that info.It would result in lose market even if at a moment if we felt that we are going as per plan than with the passage of time we would start losing sales eventually losing our future sales and goodwill along with customer loyalty. At anytime we wont be having update of govt and it could cause us heavy damage as we would be working by mistake against govt policies. It can benefit in the form of save of cos5ts as mentioned in part (a). It would save costs for us but it can result in low quality product and at the last it could have liquidity problems for our business.External info can be found by any source outside the organization for eg mainly trade union competitor govt. So overall it wont be good to just rely on internal info because our info systems would require these info to make decisions and if we lose them then it would be disastrous for us. Mistakes Amt of data Online and offline update Disc storage Processing power reqd for large systems Investment in hardware Info requirements change of semior executive over time Maintainence and support costs would change Sources of data Restricted picture of competitor’s Info system like eis cannot be defned as an eis without info system No indicator of performance comparison Lack of decision making Out of line with industry damaging firm Lack of info of competitior deals about a product Out of date info invaluable Customer info lost Lose damaging to firm Survival and growth of business Eis wont be able to good decision making because of lack of info New technological breakthrough and unnecessary research and development Lack of info of trends They couldn’t be able to predict the market Incorrect pricing Marketing info would be forgone So overall it is good but in short term
