How is the scope of an engagement determined?
Depending on the business goals, challenges and size of the organisation, an engagement scope is typically determined during the initial consultation sessions. For complex challenges and enterprise clients, we typically recommend an assessment phase at the beginning of the project. This ensures that we identify and prioritise everything correctly and develop the best solution to meet your goals.
How is a consulting project started and organised?
Although we customise just about everything to your business needs and goals, a typical consulting engagement is started and organised in the following ways:
- Initial consultation meeting(s) to determine your goals and current business challenges.
- If we require deeper information before or during building a proposal, we’ll have you sign a mutual NDA (non-disclosure agreement).
- We’ll develop a proposal that includes a SOW (statement and scope of work), pricing, timelines and any options or recommendations.
- Once the scope of the project is agreed upon, we’ll establish you in our secure systems for effective collaboration (if applicable). This will also include a regular communications plan and milestone reporting.
- We’ll then work our magic and execute.
- Towards the end of the project, we’ll finalise knowledge transfer so the results are sustainable.
- Although we’ll do an official closeout of the project, we’ll always be checking in to ensure that everything is working the way it should and you continue seeing the results you expect.
We want your OTIFYD experience to be one you’ll never forget in a good way. Working with consultants shouldn’t be a hassle. We work with you and your teams to make sure the experience and process are great while working towards your goals.
Do you do fixed price or time and materials contracts?
We do both.
Depending on the scope of the project, we typically develop fixed-price contracts. This allows you to have a defined budget with no surprises. Time and materials contracts are more appropriate for short-term consulting engagements or engagements that are more urgent and there isn’t time to properly scope the core issue(s) during the proposal phase.

I’m concerned about travel costs. How much travelling will be required?
Because our success is dependent on your success, we stay very cost conscious. In fact, we try and eliminate travel as much as possible. It saves both money and time. We have worked hard to build virtual and remote working environments that make this possible. Depending on the goals of the engagement, some travel might be required. We will determine that together as we define the engagement plan and scope.
