During decline, demand for a good begins to taper off, and the firm may opt to discontinue the manufacture of the product. This is so, if revenue for the product comes from efficiency savings in production, over actual sales of a good/service. However, if a product services a niche market, or is complementary to another product, it may continue the manufacture of the product, despite a low level of sales/revenue being accrued. 
Using Dr Dave Chaffey's approach, the digital marketing planning (DMP) has three main stages: Opportunity, Strategy and Action. He suggests that any business looking to implement a successful digital marketing strategy must structure their plan by looking at opportunity, strategy and action. This generic strategic approach often has phases of situation review, goal setting, strategy formulation, resource allocation and monitoring.
The category/brand development index is a method used to assess the sales potential for a region or market and identify market segments that can be developed (i.e. high CDI and high BDI). In addition, it may be used to identify markets where the category or brand is under-performing and may signal underlying marketing problems such as poor distribution (i.e. high CDI and low BDI).
Market nicher: The market nicher occupies a small niche in the market in order to avoid head to head competition. Their objective is to build strong ties with the customer base and develop strong loyalty with existing customers. Their market posture is generally neutral. Their strategy is to develop and build the segment and protect it from erosion. Tactically, nichers are likely to improve the product or service offering, leverage cross-selling opportunities, offer value for money and build relationships through superior after sales service, service quality and other related value adding activities.
After setting the goals marketing strategy or marketing plan should be developed. The marketing strategy plan provides an outline of the specific actions to be taken over time to achieve the objectives. Plans can be extended to cover many years, with sub-plans for each year. Plans usually involve monitoring, to assess progress, and prepare for contingencies if problems arise. Simultaneous such as customer lifetime value models can be used to help marketers conduct "what-if" analyses to forecast what potential scenarios arising from possible actions, and to gauge how specific actions might affect such variables as the revenue-per-customer and the churn rate.
Define your marketing methods. Once you understand your customers, market, and resources, choose the marketing mix that will most effectively promote your business and share your USP. How can you show customers the value of your products or services and persuade them to make a purchase? Will direct mail, online advertising, SEO, TV ads, or trade shows be an effective way to reach customers? What strategies are your competitors using? Will any of those work for you, or do you need different marketing tools?
Gap analysis is a type of higher order analysis that seeks to identify the difference between the organisation's current strategy and its desired strategy. This difference is sometimes known as the strategic gap. Mintzberg identifies two types of strategy namely deliberate strategy and inadvertent strategy. The deliberate strategy represents the firm's strategic intent or its desired path while the inadvertent strategy represents the path that the firm may have followed as it adjusted to environmental, competitive and market changes. Other scholars use the terms realized strategy versus intended strategy to refer to the same concepts. This type of analysis indicates whether an organisation has strayed from its desired path during the planning period. The presence of a large gap may indicate the organisation has become stuck in the middle; a recipe for strategic mediocrity and potential failure.
