Choosing an Implementation Model for IT and ERP Systems
Wondering whether a fixed-price model, Time & Material, or an agile methodology is the better fit? In this article, we go through the various implementation models in detail, weigh their pros and cons, and compare two popular approaches - fixed-price and flexible. Find out which one best fits your business and gives your project the best chance of success.
In a world of fast-changing technology and rising business expectations, choosing the right model for implementing IT and ERP systems is critical to a project's success. As implementation specialists who've been through it all, we want to share what we've learned about the different project delivery models, and compare two popular approaches: the fixed-price model and Time & Material.
Models for implementing IT solutions and ERP systems
There are many ways to run an IT project, differing in how they approach planning, management, and billing. Below are the most popular ones:
1. Fixed Price approach
How it works: A fixed price is set for the whole project, with the scope and requirements precisely defined during the implementation analysis phase.
Characteristics: Rigid planning, low flexibility, most of the risk sits with both sides of the project.
2. Time & Material
How it works: The client pays for the team's actual hours worked and materials used, and the project scope can change during delivery.
Characteristics: High flexibility, an iterative approach, cost risk sits with the client, better odds of a satisfying outcome for both sides.
3. Agile methodology
How it works: Groups together methodologies focused on iterative, incremental product delivery, such as Scrum or Kanban.
Characteristics: Flexibility, close collaboration with stakeholders, frequent delivery of working product versions.
4. Hybrid model
How it works: Combines elements of the fixed-price and agile approaches.
Characteristics: Strategic planning combined with flexible delivery, a balance between structure and adaptability.
5. Dedicated Team model
How it works: The provider gives the client a team of specialists working exclusively on their project.
Characteristics: Client-side control, team scalability, long-term collaboration.
6. Risk-Reward Sharing model
How it works: The provider and the client share both the risk and the rewards of the project.
Characteristics: Shared goals, motivates the provider to achieve the best outcomes, a flexible approach.
7. Outcome-Based model
How it works: The provider's payment depends on achieving specific business or technology outcomes.
Characteristics: A focus on effectiveness, minimized risk for the client, high-quality delivered solutions.
8. Cost-Plus model
How it works: The client covers the actual project costs plus an agreed margin for the provider.
Characteristics: Cost transparency, lower risk for the provider, room to introduce changes.
9. Staff Augmentation
How it works: The provider supplies specialists who join the client's existing team.
Characteristics: Quick access to talent, project control stays with the client, flexible staffing.
10. Managed Services
How it works: The provider takes full responsibility for specific IT functions or processes on the client's behalf.
Characteristics: Responsibility is transferred, fixed costs, the client can focus on strategic aspects of the business.
11. Prototyping model
How it works: Quickly building prototypes to gather feedback before full implementation.
Characteristics: Reduced risk, better understanding of requirements, faster iterations.

Comparing the fixed-price model and Time & Material
Let's take a closer look at two popular approaches: the fixed-price model and Time & Material.
Project scope
Fixed-price model: The scope is precisely defined at the start. Any changes require renegotiating the contract or analysis document.
Time & Material: The scope is flexible and can be adjusted as the project progresses.
Planning
Fixed-price model: Detailed planning before work begins. The schedule is rigid.
Time & Material: An iterative approach to planning. Uses agile methodologies.
Costs
Fixed-price model: A fixed price is set. The client knows the project cost upfront.
Time & Material: Costs depend on the actual amount of work involved. Harder to predict.
Risk
Fixed-price model: Most of the risk falls on the provider, who has to deliver within the agreed budget and timeline.
Time & Material: Greater risk falls on the client, due to the unpredictability of costs.
Flexibility
Fixed-price model: Low flexibility. Changes are difficult to introduce.
Time & Material: High flexibility. The project can be adjusted on an ongoing basis.
Summary
Choosing the right implementation model depends on the specifics of the project, business needs, and how much uncertainty there is around the final shape of the solution. If a project has a clearly defined scope and the requirements won't change, the fixed-price model may be a good fit. In a dynamic business environment, though, where flexibility and quick adaptation matter most, Time & Material or agile methodologies tend to be more effective.
When working with clients, we typically use agile methodologies, because they let us respond quickly to our clients' changing needs, deliver value in short iterations, and maintain close collaboration at every stage of the project.
