Every business experiences highs and lows. However, there's a lot that can be learnt from setbacks as well. It's about identifying what went wrong, why it happened, and how things can be improved. Whether you are a startup or an established business, unless you know your team's strengths, shortcomings, and potential challenges, creating the right strategy for the future becomes tricky. One tool that helps achieve this goal is post-mortem analysis. Unlike what it sounds like, it's not a failure audit but a tool for growth. It can be used to turn any missteps into momentum. This strategy can help your business thrive in today's fast-paced, innovation-driven economy.

In this article, you will be introduced to why performing a post-mortem analysis is important, the steps to conduct one effectively, and everything related to it to help your startup grow and prosper.

Post-Mortem Analysis Meaning

A post-mortem analysis is a systematic evaluation undertaken after a specific event, project, or campaign is completed and it can also be conducted periodically to drive continuous improvement. Like a normal post-mortem investigation, this analysis from a business's perspective helps identify successes and failures to identify areas for improvement in the future. To do this, data is gathered from the business's team members and stakeholders to identify:

  • Strengths or everything that went well
  • Issues or challenges faced
  • Opportunities for further optimisation and improvement

This data is used to formulate an effective business strategy based on actionable insights to optimise future endeavours. In a way, it is a tool for continuous learning and improvement.

Different Types of Post-Mortem Analysis that Businesses Do

Campaign level

A post-mortem analysis of a campaign helps to understand the effectiveness of a specific marketing campaign. By analysing and evaluating the results and performance, you can identify what worked, what didn't, and what can be improved. For instance, a post-mortem analysis of a social media advertising campaign can help analyse the effectiveness of different channels and creatives in reaching the target audience.

Project level

As the name suggests, this post-mortem analysis helps evaluate the highs and lows of a specific project. To do this, review the project objectives and the actual outcomes. It helps identify any challenges faced during the project and determine what worked well and can be improved. For instance, a post-mortem analysis of a software development project can help compare the projected outcomes against the actual ones to identify areas of improvement in future projects.  

Business level

In this post-mortem analysis, a business's overall performance is evaluated using different metrics such as revenue, customer satisfaction, profitability, and market share. For instance, a useful post-mortem analysis example for a business is to compare its performance in the previous year against the current year. This can help identify the effectiveness of its business strategies and initiatives.

How to Conduct an Effective Post-Mortem Analysis

Make it inclusive

The first step to conducting an effective post-mortem analysis is to make it inclusive. After all, an effective post-mortem considers all the work that contributed to the results achieved. For instance, if a campaign involves plenty of design work or website updates, then everyone involved in it, from the design, engineering, and product teams, must be present along with the marketing team. Similarly, if any external agencies were used, the post-mortem analysis must include all those involved. So, ensure the invite list includes all the stakeholders and everyone relevant in the context to obtain their insights.  

Set goals or KPIs

Performance evaluation becomes challenging if the parameters of target metrics aren't established. Ensure the goals or target key performance indicators (KPIs) are established before the analysis. Having quantifiable metrics makes it easier to dissect the performance and allows the team to reflect on the targets they achieved, the missed ones, and the variables contributing to the overall outcome.

Gather the needed data

The required data must be gathered before a post-mortem analysis can be conducted. Without supporting data, the post-mortem will not be meaningful. For instance, a post-mortem analysis for a general project can include the costs, project schedule, and any other business-centric data. Similarly, questionnaires can also be circulated to stakeholders to obtain honest answers. Examples of some questions that can be included are:

  • What were the key factors that contributed to the project’s success?
  • Were there any early warning signs we missed or overlooked?
  • Which decisions had the most significant impact whether positive or negative and why?
  • Did we allocate time and resources effectively throughout the project?
  • What did we learn that should be documented for future projects?
  • Which tools, processes, or systems helped and which ones held us back?

Define the purpose

The purpose of conducting the post-mortem analysis is conflict resolution and identifying areas for improvement. To ensure the session is productive, establish an agenda and circulate it to the participants before it begins. A clear agenda helps stick to the talking points and promotes a reflective conversation while keeping the negatives at bay. For instance, the agenda for a post-mortem analysis can include an introduction, a general overview of the results, a discussion of everything that went right, and suggestions for improvement. Ensure the meeting concludes positively to keep up the team's morale. A moderator can be assigned if needed to ensure the group stays on track and all the items mentioned in the agenda are addressed.

Document the outcome and assign action items

Documenting the outcome is a simple yet essential aspect of conducting an effective post-mortem analysis. This includes summarising the highlights and major outcomes along with the action items from the meeting. Various AI notetaking tools can be used to record the meeting and produce a transcript. It should also include the meeting's takeaways, recommendations, and action items. If a moderator is used, then they will be responsible for documenting the meeting and creating a final report. Once this document is ready, ensure it is easily accessible to all the participants.

What Are the Common Mistakes that You Should Avoid

Insufficient preparation

For an effective post-mortem analysis, it's important to have the required data. This can include financial analysis, customer feedback, insights from stakeholders, etc. If the data is inadequate, incomplete, irrelevant, or biased, the post-mortem analysis will be ineffective. 

The blame game

Pointing fingers and blaming quickly derail the effectiveness of a post-mortem analysis. Playing the blame game festers a toxic work culture. Instead, an open and productive discussion is needed to identify what went wrong, what worked, and what can be improved upon.

Ineffective communication

Effective communication and collaboration are needed to ensure the post-mortem analysis is a success. Lack of either can limit and hinder the process resulting in limited solution sharing.

No definite outcome

A post-mortem analysis is successful only when clear outcomes can be derived. Whether it is recommendations for better process management and implementation, solutions to challenges faced in the past, or redefined business strategies, the analysis must end with an action plan. Merely identifying the hurdles without remedying them also defeats the process.

Frequency of Post-Mortem Analysis

The ideal frequency for conducting post-mortem analysis essentially depends on the context. A general practice is to conduct annual post-mortem analysis to determine how the year went and reflect on the results before establishing goals for the following year. This helps refine and adapt new business strategies. Similarly, campaign or project-specific post-mortem analysis must be conducted as soon as a campaign or a project ends. It must be conducted while the feedback is still fresh in the team's mind for better results.

Benefits of a Post-Mortem Analysis

Identify successes and failures

A post-mortem analysis helps the business identify what went well and everything that was undertaken to obtain the said results. It helps identify any processes or patterns that can be repeated for future success. For instance, if a project generated better results than initially predicted, look at everything that was undertaken to achieve those results. By reflecting on the highs, it can help fine-tune the operations while building morale.

 Similarly, it must also include everything that didn't go according to the plan, challenges faced, and mistakes made. After all, success isn't defined only by what went right but from what can be learned from mistakes too. Let's assume a rebranding campaign was executed but the customers didn't respond to the rebrand. Instead of viewing this as a failure, conducting more thorough customer research in the future can be a takeaway.

Analyse business outcomes

Analysing the project outcomes helps teams understand what happened and the reasons for the same. This includes everything from reviewing the project data and gathering feedback from stakeholders and teams to conducting a thorough analysis of the project's performance. By doing this and using KPIs and metrics, it becomes easier to evaluate the project outcomes effectively. Another benefit of doing this is it helps obtain insights into what worked and what didn't. This information can be used to develop strategies to improve future project outcomes.

Implement changes and improvements

A post-mortem analysis is effective once the insights obtained from it can be used to implement changes by turning the insights into actionable items. This can be done by developing a plan to assign action items to different team members, addressing the areas for improvement, and establishing a timeline for implementation. By focusing on critical changes and improvements, business outcomes can be improved. However, it's also important to regularly review and update the plan to ensure the team is on the right track.

Overcome challenges and resistance

Through post-mortem analysis, you can help your team address and overcome any obstacles and barriers to change. When potential challenges can be identified well in time and strategies can be developed to overcome them, it improves the team's performance. In turn, this improves their morale. When put together, it helps overcome any resistance and creates a more cohesive team. However, this requires clear and transparent channels of communication along with a flexible plan that can be modified as per any changes needed.

Refine operations and processes

An essential aspect of the post-mortem process is to help teams optimise their efficiency and workflows. This can be done by analysing their current processes and identifying areas for improvement. After this, business strategies can be brainstormed to refine and optimise the results generated. Lean principles and process mapping tools can be used to identify areas for improvement and develop action items to address them.

Create a culture of continuous improvement

A major benefit of effective post-mortem analysis is it helps create a culture of continuous learning and improvement. By fostering a growth mindset, a business culture based on feedback, learning, and improvement can be created. Another benefit is it helps encourage experimentation and learning from failure through continuous feedback and evaluation. However, to achieve all this, post-mortem sessions must be inclusive and collaborative.
