‫تعاریف متفاوت از هوش تجاری‬
‫• هوش تجاری مدیریت درست و موثر اطالعات برای‬
‫ً به ارتباط بین کاربر‬
‫هدفی تجاری است و اساسا‬
‫و سیستمهای فناوری اطالعات مربوط میگردد‬
‫• هوش تجاری عبارت است از شرح نیازهای سازمان‬
‫برای تجزیه و تحلیل به همراه گزارشدهی‬
‫• هوش تجاری رویکردی راهبردی است برای هدفگذاری‬
‫به صورت سیستماتیک‪ ،‬ردیابی‪ ،‬مخابره و نهایتا‬
‫ً‬
‫تبدیل و ترجمه سیگنالها و عالئم ضعیف کسبوکار‬
‫به یکسری اطالعات کاربردی که اساس تصمیمگیری‪-‬‬
‫های راهبردی شوند‬
‫‪2‬‬
‫• هوش تجاری به عنوان تغییرشکلدهندهای آگاه و‬
‫روشمند است که دادههای مختلف را از منابع‬
‫مختلف دریافت و به شکلهای جدید تغییر میدهد‬
‫تا اطالعاتی نتیجهگرا و تجاری را فراهم کند‬
‫• هوش تجاری مبحث بسیار وسیع است که کارکردها‬
‫تعاریف متفاوت از هوش تجاری‬
‫معمول عنصر اصلی آن‬
‫ا‬
‫• هوش تجاری که انبار داده‬
‫محسوب میشود برای انجام تجزیه و تحلیلهای‬
‫پیچیده و بهبود عملکرد در جستجوهای پایگاه‬
‫داده – که شامل هزاران رخداد است‪ -‬ایجاد و‬
‫بهینهسازی شده است‪ .‬هوش تجاری در واقع برای‬
‫ایجاد ارزش در سازمانها بر پایه داده و به‬
‫بیان دقیقتر واقعیات میباشد‪.‬‬

‫• هوش تجاری دسته وسیعی از برنامهها و تکنولوژی‪-‬‬
‫ها را دربر میگیرد که برای جمعآوری‪ ،‬ذخیره‪-‬‬
‫سازی‪ ،‬تجزیه و تحلیل و فراهم کردن دسترسی آسان‬
‫به دادهها به وجود آمده است تا کاربران بنگاه‬
‫را در اتخاذ تصمیمات درست تجاری کمک کند‪.‬‬
‫همچنین شامل مجموعهای از مفاهیم و روشها است‬
‫که تصمیمگیریهای تجاری را با استفاده از سیستم‪-‬‬
‫های کاربردی مبتنی بر حقایق بهبود میبخشد‪.‬‬
‫تعاریف متفاوت از هوش تجاری‬
‫• هوش تجاری ابزاری است که توسط بنگاهها برای‬
‫جمعآوری‪ ،‬مدیریت‪ ،‬تجزیه و تحلیل دادهها و‬
‫اطالعات اساسی و ساختیافته و یا غیر آن‬
‫استفاده میشود و این کار با به کارگیری‬
‫قابلیتهای فناوری اطالعات صورت میپذیرد‪ .‬هوش‬
‫تجاری همچنین از دادههای معتبر جمعآوری شده‬
‫حاصل از فرایندهای عملیاتی روزانه استفاده‬
‫کرده و با تبدیل این دادهها به اطالعات و دانش‬
‫از احتماالت و بیخبریها در بنگاه جلوگیری می‪-‬‬
‫کند‪.‬‬

‫• هوش تجاری با فرایندی سیستماتیک سروکار دارد‬
‫تا با تجزیه و تحلیل و مدیریت دانش و اطالعات‬

Business Case Assessment Activities
28
Deliverable Resulting (Step 1)
1.Business case assessment report
- Strategic business goals of the organization
- Objectives of the proposed BI application
- Statement of the business need (business problem or business
opportunity)
- Explanation of how the BI application will satisfy that need
- Ramifications of not addressing the business need and not committing
to the proposed BI solution
- Cost-benefit analysis results
- Risk assessment
- Recommendations for business process improvements to the
operational systems or to the operational business processes and
procedures
The assessment report should also have a one- or two-page executive
overview that summarizes the details of the report.
