What is an Engagement Model?

In mobile app development, the engagement model definition is that it is a framework or agreement. It helps to outline the collaboration and interaction between the client and the mobile app development company.

This model defines the terms, conditions, and specifics of the partnership, establishing a structured approach to project execution. The engagement model typically covers various aspects of the development process, including roles, responsibilities, pricing, project management, communication, and other relevant factors.

Why Is There a Need For An Engagement Model?

An engagement model is a framework that defines the way groups interact and collaborate.

When outsourcing your mobile app development project to a service provider or agency, it’s crucial to establish a set of guidelines, essentially forming an engagement model. This agreement clearly defines roles, responsibilities, levels of control, hourly commitments, pricing structures, and other critical factors. Choosing the right engagement model can expedite the realization of your app idea.

The necessity for a well-defined engagement model arises due to the dynamic nature of mobile app development. Every feature, functionality, or project modification incurs costs.

Statistics indicate that 16% of outsourced projects fail due to poor communication and engagement issues. 

With a predefined contract, challenges may arise in project management, budget planning, app development costs, project timelines, and overall application quality, potentially leading to satisfaction with the final product. Therefore, an engagement model becomes essential to mitigate these challenges.

Key Components of an Engagement Model

1. Roles and Responsibilities

Clearly defining the roles and responsibilities of both the client and the development team. This includes specifying who is responsible for what tasks and deliverables.

2. Project Management

Outlining the project management approach, including methodologies, tools, and communication channels to be used throughout the development lifecycle.

3. Scope of Work

Defining the scope of the mobile app development project., including features, functionalities, and deliverables. This helps manage expectations and avoid scope creep.

4. Pricing and Cost Structure

Specifying the price model, whether it’s based on hourly rates, fixed pricing, or another arrangement. This section outlines the cost structure and payment terms.

5. Timeline and Milestones

Establishing a timeline for the project, including key milestones and deadlines. This helps in tracking progress and ensuring timely delivery.

6. Communication Plan

Defining the communication channels, frequency of updates, and reporting mechanisms to ensure effective and transparent communication between the client and the development team.

7. Exit Strategy

Defining the terms and conditions for concluding the engagement, including the handover process, documentation, and ongoing support or maintenance agreements.

Types of Engagement Models

Fixed Price Model

This model is often known as a fixed bid or lump sum contract. It is pretty straightforward. 

Imagine you’re ordering a customized cake as you agree on the design, size, and delivery date beforehand, and also the exact cost. Just by its name, you can understand that this model revolves around locking in the costs of your projects well before the development phase begins.

It involves meticulously documenting all the project requirements, outlining a detailed project scope, and establishing a strict timetable with clearly defined milestones. Above all, it emphasizes predictability.

A thorough business analysis should be conducted with extensive interviews to gather every intricate detail about the project. To identify the use cases, create user stories, and develop wireframes to aid in visualizing the user experience and interface.

The outcome of this model is a comprehensive technical specification, cost estimation, development schedule, and prototype.

Advantages of the Fixed Price Model

1. Predictability and Transparency: you receive a clear budget and deadlines well in advance of the development commencement. By ensuring predictability and transparency throughout the project.
2. Reduced Client Management and Supervision: unlike other models, the fixed price model requires less client involvement in management and supervision since the development team is equipped with specifications, scope of work, and a predefined budget.
3. Precise Project Outcome: Right from the start, you have a solid understanding of the final product’s appearance, and you can anticipate it being delivered exactly as envisioned.
4. Ideal for Building Trust: Particularly suitable for establishing trust with a new partner, the fixed price model provides a structured and transparent framework that fosters confidence in project outcomes.

Drawbacks of the Fixed Price Model

1. Higher Costs: The fixed price model is relatively more expensive as the development company assumes full risk management responsibility, incorporating all potential risks into the upfront cost. This makes fixed-price contracts the costliest among various engagement models, with hourly rates potentially being 1.5 to 2 times higher than other contract types.
2. Time-Consuming Requirements Gathering: The process of gathering and analyzing requirements can be time-consuming. For smaller projects, it may take a couple of weeks, while massive undertakings might require several months. Although this investment in time and resources might seem extensive, the fixed price model must function effectively. Without a clear definition of requirements, the model’s benefits are compromised.
3. Limited Flexibility: there is minimal flexibility, especially when adding or modifying features. Shortcomings in the initial phase can have negative repercussions in later stages and on the final product. Overlooking a small feature at the project’s outset or deciding later to expand certain functionalities necessitates renegotiating the entire agreement. This flexibility can lead to a challenging dynamic between the client and the development team bound by struct timelines and budget constraints.

When to Opt for the Fixed Price Model

1. Well-Defined and Stable Requirements: choose this model when your project requirements are clear and unlikely to undergo significant changes during development.
2. Short-to-Medium-Term Projects: Opt for the fixed price model for projects with a duration ranging from short to medium-term. Typically lasting up to several months.
3. Compatible with Waterfall or Modified Agile Approach: The fixed price model aligns well with the waterfall development methodology, where development stages occur sequentially. It can also be adapted to Agile by breaking the project into smaller phases with billing based on achieved milestones.
4. Initial Cooperation or Minimum Viable Product (MVP) Development: Consider using the fixed price model at the outset of a partnership or when developing an MVP to establish a clear framework and build trust.

Time and Material Model

In practical terms, time and material contracts (often called T&M) offer significantly more adaptability than fixed-price engagement model alternatives. A situation where the product vision could be clearer, the market dynamics are evolving rapidly, or the technology landscape is changing swiftly, predicting the full and final project scope becomes challenging.

In such scenarios, there are two approaches:

• Breaking the project into smaller, more manageable parts and proceeding with the fixed price model.
• The technology landscape is changing swiftly, and predicting the full and final project scope becomes challenging.

The time and material engagement model demands increased client involvement. But it simultaneously provides greater control over the project. It allows adjustments to the team size and composition on the fly, depending on emerging requirements and current priorities.

Advantages of Time and Material Model

1. Exceptional Flexibility in Budget and Scope: The Time & Material model offers unparalleled flexibility concerning project budget and scope. It excels in accommodating requests for additions or changes during the development process.
2. Optimal Utilization of Agile Methodology: This engagement model fully leverages the Agile development methodology to drive robust projects efficiently. It ensures adaptability by breaking down the project into smaller tasks and allowing clients to prioritize based on current business needs.
3. Great Control for the Client: Clients enjoy a significantly higher degree of control over the project. It ensures adaptability by allowing clients to prioritize based on current business needs.
4. Low Risk for Both Clients and Developers: The time and material engagement model carries lower risk for both clients and developers, providing a more adaptable and collaborative approach to project development.
5. Accelerated Development Start: The model facilitates a quicker development start by expediting the requirements-gathering stage, enabling the project to commence swiftly.
6. Cost Effective for Clients: Clients benefit from cost-effectiveness, as developers do not have to overcharge for potential risks. This results in a more economical solution for clients.

Drawback of Time and Material Model

1. Increased Client Oversight Required: The Time and material model necessitates more active involvement and oversight on the part of the client throughout the project.
2. Lack of Definitive Time Commitment: There are no guarantees that the project will be completed within a specific timeframe, introducing uncertainty regarding project timelines.
3. Potential Discrepancy in Projected Vs. Actual Costs: There may be a variance between the initially projected estimate and the actual costs incurred during the project, leading to potential discrepancies.

When to Opt for the Time and Material Model

1. Uncertain or Evolving Requirements: Choosing the time and material engagement model when the project requirements lack precision or when investing substantial time and resources to define them is not feasible.
2. Anticipation of Changing Requirements: Opt for a time and material engagement model when there’s a high likelihood that project requirements will change the development process.
3. Longer-term and Larger Projects: Time & Material is suitable for larger projects spanning several months to a few years.
4. Subsequent Iterations of an MVP: Consider this model for later iterations of a Minimum Viable Product (MVP) that was initially completed under a fixed price model.
5. Projects in Rapidly Shifting Markets: Choose the time and material model for projects targeting rapidly evolving markets or incorporating cutting-edge technologies.

Cost Plus Model

The cost-plus engagement model is commonly utilized for outstaffing or personnel leasing. Where one company lends its specialists to another company for a specified duration. In this setup, the client can essentially “borrow” a team, who work until the project is completed or until their services are no longer needed.

Under this engagement model, the client pays the developers’ salaries along with all related expenses, plus a contractor’s fee. The contractor provides a detailed breakdown of evidence-backed expenses related to the project at the end of each month. This high level of transparency has led to the model being labeled the Open Nook Model.

Subtypes of Cost Plus Model

1. Cost Plus Fixed Fee: In this subtype, the contractor’s fee is predetermined, similar to a fixed-price contract.
2. Cost Plus Percentage Fee: In this subtype, the contractor’s fee is proportional to the total expenses incurred on the project. However, it’s advisable to be cautious with this model as it may incentivize the contractor to spend more to increase profits.
3. Cost Plus Incentive Fee: In this subtype, the contractor’s profit is determined by the ratio of the target cost to the actual cost. Essentially, the developer receives more compensation for sending less or working more efficiently. 

Overall, with its variations, the cost-plus engagement model is particularly suitable for scenarios where personnel leasing is involved, providing transparency and flexibility in managing project costs.

Advantages and Drawbacks of the Cost Plus Model

The advantages and drawbacks of the cost-plus model closely resemble those of the time and material model. It is typically more cost-effective, and faster, and entails lower risk compared to the fixed price bid. However, it demands increased client oversight. A notable benefit is its exceptional cost transparency.

A distinctive drawback is that in many cost-plus contracts, developers may stipulate that clients must provide a 2-3 months’ advance notice for service cancellation.

Conclusion

As a concluding note, this is to emphasize the significance of caution and transparency in outsourcing app development.

Selecting the right engagement model for your mobile app project is a critical decision that can significantly impact its success. The engagement model serves as a framework that defines the collaboration between the business owner and the mobile app development company. By outlining roles, responsibilities, pricing structures, project management approaches, and more.

There are many engagement model examples. Ultimately, the choice of engagement model depends on the nature of your project, the level of flexibility required, and your relationship with the development partner.

Careful consideration of the project’s specific needs and alignment with the chosen engagement model will contribute to a successful and satisfying mobile app development journey.
