This assignment discusses the strategic alliance between SABIC and ABB to achieve Saudi Vision 2030. The manager of SABIC will have to make decisions on various aspects such as HR, marketing, and finance, considering the experience of individuals involved. The prescriptive decision-making method involves planning, data collection, analysis, and evaluation to reach a particular decision. Other methods used include paired comparison analysis, consultation, voting, and consensus achievement through social network-based approaches. The study concludes that strategic alliances are effective in gaining entry into new markets, reducing risk, and guiding correct decision-making.
