How do you optimize your core activities with value chain analysis?

I want to add my experience in analysing a fast food chain's value chain to value its business. I break the value chain as follows: Core activities [1] Inbound logistics - Procure Veggies (lettuce, tomato and spinach) from suppliers crucial for quality and taste. [2] Operations - Quality of cooks and kitchen staff to maintain taste, hygiene and quality. [3] Outbound logistics - Efficient handling and order delivery (online + offline) [4] Sales and Marketing - Advertising (Zomato, Google and Offline), Promotions (Discounts+Cashback), Attractive menu [5] Service - Customer service, dining experience Support activities [1] Procurement - Selecting vendors [2] HR - Hiring, Training staff [3] IT - POS and Ordering [4] Infra - Physical space

I like to share my experience when doing value chain analysis for Indian smartphone manufacturer: [1] Primary activities - Designing, Assembling and Selling [2] Support activities - managing supply chain, customer service and developing new tech. [3] Map the above activities in a diagram showing how each activity is linked. [4] Then I analysed how the design process contributes to better smartphone and cost involved on each activity. [5] I identified differentiation which for the company was the sleek design [6] Interdependencies were supply chain management [7] Identify opportunities to improve the value chain and threats to watch out like new player entry. I fine-tuned the value chain resulting in cost improvement and better quality.

Having done numerous value chain analyses of multiple businesses, my insights include: [1] Value chain analysis is not an analysis of internal strengths and weaknesses but a lens that captures how these aspects impact external stakeholders. [2] Apple's strategy is not producing iPhones but crafting experiences that resonate with its users, which is the reason behind its vast market share and growth. [3] Toyota leverages value chain analysis for cost efficiency, Starbucks use it for stakeholder alignment (loyalty and brand), and Amazon leverages it for innovation (improvement in the distribution network and customer experience). Value chain analysis gives a 360 view of how your strategy impacts a broader ecosystem to amplify value creation.
