Programmes underestimate/don’t acknowledge time, cost, and external factors and the impact these may have. Often they don’t account for the time it will take for people to understand and become familiar with a new way of doing things or cost in sufficient change management. There is also often significant pressure to provide the shortest possible time frames. In the long run, however, this will lead to significant disappointment as expectations set early are rarely met.
Out of all the Fundamental Challenges, Over-optimism is most likely to be resolved over time as the programme progresses and estimates become more realistic. However, the negative impacts of Over-optimism are extensive. The three main symptoms of Over-optimism are unrealistic scheduling, lack of a long-term plan, and poor business case development and clarity.
Unrealistic scheduling comes from having a vision with insufficient detail for realistic and accurate costing and scheduling, and over-optimism about how quickly people and an organisation can absorb change. Approvals and assurance processes have not been included in the scheduling and long-term plans for the programme.
Lack of a long-term plan means the delivery plan has not been stress-tested thoroughly and feedback on deliverability is not incorporated by the team. The programme does not actively work to avoid creating unrealistic expectations and it does not take into account real-world timescales.
Business case development and clarity indicates that significant time has not been spent on understanding the scope and scale of the programme, costing and funding, scheduling and risk. Often there is too little attention paid to the operational and people elements of the transformation.
Good practice – for example as articulated in the GPDF – requires scope to be set and estimates to be developed to greater accuracy and finalised by FBC approval. It is possible for a project to use the governance process to its benefit and, from its stakeholders, force agreement and / or accept uncertainty. A project should strive not to accept uncertain outcomes with fixed constraints or the opposite.
To overcome Over-optimism:
Look at the Plan and Design Lenses.
Ask yourself the following:
- Are the benefits linked to the vision realistic and have they been tested with wider stakeholders and independently assessed as achievable?
- Has the scope and scale of the final organisation or service been tested and agreed, and is the level of risk around sizing understood?
- Have approvals and assurance processes been included in the scheduling and long term planning for the programme?
- Has the plan been stress tested thoroughly including through benchmarking and independent assessment to ensure it is deliverable?
- Has the programme spent significant time understanding the costing and the funding needed and levels of risk and contingency against key areas?
- Is it clear who owns benefits not just within the programme but in the wider department and government eco-system?
- Is there clarity about the scale of the business and people change elements of delivery, are they properly accounted for in terms of time and cost?
