Enterprise web projects often fail for predictable reasons. At Oshyn, we’ve seen hundreds of projects using leading digital experience platforms and identified three core mistakes that lead to budget overruns, launch delays, or mid-project rescues.
Issues usually stem from scoping without understanding the platform, poor decision-making during design, and treating content migration as an afterthought rather than a key architectural decision.
These failure patterns are predictable and appear when agencies run enterprise DXP projects without the right technical foundation. That predictability means the problems are preventable.
In this blog, we’ll explain what each mistake looks like, why it happens, and what the teams that avoid it do differently.
Key Takeaways
-
Platform-agnostic scoping is the most common cause of overrunning budgets or timeline delays in enterprise web development. It occurs when a project is estimated based on design complexity without assessing how those requirements translate to the specific CMS or DXP powering the build.
-
Issues that occur during the design phase are usually due to governance failure rather than creative ones. Without a defined decision-making framework established at the start of a project, there is no mechanism for resolving stakeholder conflicts, and there is not enough budget left for development or testing by the time design closes.
-
Content migration is consistently the most underestimated aspect of enterprise web development and must be treated as a design-phase architectural decision, not a technical task handled after the build is complete.

Oshyn is a digital agency with deep expertise in leading enterprise DXPs, including Adobe, Sitecore, Optimizely, Contentstack, and others. We help agencies and in-house teams avoid these problems by integrating technical review, governance support, and content planning from the start of every project.
Mistake #1: Content Gets Underestimated or Relegated to an Afterthought
Content is now critical to discoverability, with factors such as content structure and semantic clarity determining whether a brand is surfaced by AI search engines. These are architectural decisions that must happen during the design phase, not after launch, because the structure of the content model shapes what can be built, and what gets built shapes whether content can be found.
Additionally, content migration, particularly from a legacy system that doesn’t follow modern principles, is consistently the most underestimated aspect in enterprise web development. It takes longer than planned because organizations don’t actually know how much content they have or what state it’s in.
Unfortunately, what marketing teams might think is a manageable content library is often years of accumulated pages, assets, metadata, taxonomy, and component relationships that don’t map cleanly to a new content model.
Why It Happens
Companies aren’t aware of the full scope of their content until they start auditing it. Content migration is often one of the most complex tasks in the entire project, requiring decisions about content architecture that are directly tied to design and component structure.
What to Do
Content and migration planning must run in parallel with design. Teams need to have content strategists and technical architects in the same room early to define the new content model before the first component is built.
Oshyn offers content migration and structured content planning support that runs alongside the design and development phases rather than replacing them at the end. This keeps migration from becoming the last-minute blocker it is on most enterprise web projects.
Mistake #2: Scoping the Project Without Understanding the Platform
Platform-agnostic scoping most often causes budget overruns or timeline delays in enterprise web development. This happens when an agency estimates based on design complexity without checking how the requirements align with the CMS or DXP being used.
Factors such as page templates, custom functionality, and the scale of a website play a huge role in project success. For example, while a design in Figma might look straightforward, it could require building a custom component in AEM. On the other hand, a feature that the client believes requires extensive customization may be available as a native capability in Optimizely or Sitecore.
Failing to understand these differences makes client conversations harder and signals a lack of technical expertise.
Why It Happens
Some agencies excel at creative and UX, but not platform architecture. They delay technical scoping until after design approval, which creates these issues.
What to Do
Technical reviews should be included during the design phase, not after. Before designs go to the client, the implementation team should have reviewed the proposed component structure. This provides answers to questions such as whether the design is buildable within the quoted budget, whether it can leverage the platform's strengths, and whether it meets accessibility and performance requirements.
Oshyn’s design support service is specifically for these types of scenarios and helps enterprises assess design feasibility and optimize components to best fit the budget.
Mistake #3: Losing Control of the Design Phase
Issues that occur during the design phase are usually due to governance failure rather than creative ones. When there is no defined framework for who can provide input on a deliverable, who can request changes, and who has final sign-off authority, the review cycle is open to renegotiation.
Typically, this occurs when the marketing team wants one thing, IT wants another, leadership wants a third, and legal has just been added to the conversation. Unfortunately, not all of them were part of the original brief but are legitimate stakeholders in the outcome. Without a clear decision-making structure established at the start of the project, there is no mechanism for resolving the conflict.
Why It Happens
Some agencies and internal teams can lack urgency to exit the design phase quickly because they want everything to be perfect. The knock-on effect of this, which severely affects enterprise web projects, is that teams get stuck in the design phase and there is not enough time or budget left for a proper development phase or adequate testing.
However, value needs to be delivered to end customers as quickly as possible, so if you aren’t efficient in design, it can delay those benefits reaching end users and, eventually, the company's bottom line.
What to Do
Managing build phases is a unique skill, and teams that know how to manage the creative process are unlikely to be skilled at handling the changes that occur during the build/test/deploy development phase.
At the start of every project, establish who decides what and when. This allows teams to map which stakeholders have input on each deliverable, who can request changes, and who has final sign-off authority. Once that structure exists, a checkpoint process can validate and approve work at meaningful intervals rather than leaving everything open to revision until the last moment.
Oshyn is an experienced implementation partner who has run multiple enterprise engagements and provides the required structure to ensure projects are under complete control. Through the Oshyn Wave approach and our iterative development, projects are implemented with client and agency buy-in at each iteration.
How to Set Your Next Web Project Up for Success
The mistakes that consistently derail enterprise web projects occur when design and development are treated as sequential disciplines handled by separate teams with no meaningful overlap. So how can you avoid them?
Design and UX Agencies: You don’t need to become a development firm to avoid these problems. But you do need a technical partner who can sit in platform conversations with a client’s IT team without losing credibility.
In-House Enterprise Teams: The earlier you bring a DXP implementation partner into the process, the more options you have. If you’re working with a design agency that lacks deep enterprise DXP experience, consider bringing in a dedicated implementation partner to work alongside them and ensure project success.
Oshyn is a digital agency with extensive experience in leading enterprise DXPs, including Adobe, Sitecore, Optimizely, Contentstack, and others. We review designs for buildability before a line of code is written, run build phases independently, and bring the platform credibility needed to work directly alongside your client's or organization's technical team.
As part of a composable implementation for Point B, Oshyn partnered with XO Agency during the design phase to validate what could be built efficiently in Sitecore. That upstream alignment eliminated a common issue with web projects and led to a 212% increase in time on site within weeks of launch.
Whether you're an agency looking for an implementation partner or an in-house team getting ready for a major digital project, we're happy to take a look at where things stand.
